19Positioning The Air JetsWhen a printed label is being fed from the SLPA onto the applicator pad, it must be held against the pad so that it can be properly positioned. The air jets located on the air jet tube direct air at the label while it is being fed, so that it does not bend or fall from the pad. Once proper positioning is achieved, the vacuum of the applicator pad initiates and holds the label into place until application.For the air jets to work correctly, they must be directed at an angle specific to the size of the label in use. Angle the air jets to a point which is approximately 1/3 the length of the current label length, as measured from the peel bar. Wider or longer labels may approximate the air jet angle to a point beyond 1/3 the label length, where shorter or narrower labels may target inside the 1/3 length zone. Repeated adjustment may prove necessary for optimum operation.Figure 12. Positioning the Air JetsThe air jet will typically be adjusted for proper operation prior to being shipped, but if further adjustments are necessary, proceed as follows:1. Loosen the socket head screw holding the air tube into place.2. Ensure that the proper holes in the air jet are open. The standard tube comes with #2-56NC threaded holes and some of the holes may be plugged with a small set screw. Add or remove set screws as necessary.3. Turn the air tube adjustment so that the air jets are directed at approximately 1/3 the length of the current label length as measured from the peel bar.4. Tighten the socket head screw into place to hold this adjustment.Socket Head ScrewAir Jet TubeAir JetLabelLabel BackingPeel Bar
20Chapter 1 Calibrating The PrinterCalibrating The PrinterFor printers not using smart labels, an Auto Calibrate should be sufficient to properly calibrate the printer (see next section).To calibrate printers that are using smart labels:1. Run an Auto Calibrate to set up initial values (page 21).2. Make a Media Profile printout.3. Make any necessary adjustments to Threshold Range in the CALIBRATE CTRL menu.4. Run an Auto Calibrate again (page 21).5. Make a Media Profile printout again to verify the Threshold Range you selected in step 3 is correct.6. Save the configuration, and then set the saved configuration as the Power-Up configuration (page 37).Avoid RoundedDie Cut LabelCornerPosition the lowermedia sensor in thegrey shaded area.Avoid Pre-PrintingFEED
Running Auto Calibrate21Running Auto CalibrateIMPORTANTSince manufacturing differences in media and ribbon can decrease the printer’s TOF (top-of-form) sensing reliability, you must run an Auto Calibrate to provide optimum sensor threshold values for the installed media and ribbon.1. Set the printer power switch to | (On).2. Press the key to enter the QUICK SETUP menu.NOTE: For a complete description of the QUICK SETUP menu, see page 30.3. Press ↓ and ↵ together until ENTER SWITCH / UNLOCKED displays.4. Press ↑ or ↓ until Label Length / 6 inch* displays (default).5. Press + or – until the value that matches the physical length of the installed media displays.NOTE: Selecting the correct Label Length forces Auto Calibrate to increase media advancement for long labels (to detect actual gaps, notches, or marks) and decrease media advancement for short labels.6. Press ↑ or ↓ until Gap/Mark Sensor / Disable* displays.7. Press + or – until Gap displays.NOTE: If you are using smart labels, see “Gap Sensing for Smart Labels” on page 36.8. Press ↵. An asterisk (*) displays next to the selected item.9. Press ↓ until Auto Calibrate / Run Calibrate displays.10. Press ↵. Media advances until it can accurately detect the label length indicators and then stops at the top-of-form position. The Sensed Distance value then displays for one second.11. Auto Calibrate is successful when the Sensed Distance value correctly matches that of the installed media. For Gap sensing, the Sensed Distance value is the physical length of one label plus the length of one gap.12. If GAP NOT DETECTED or PAPER OUT displays:a. Check the horizontal position of the media sensors.b. Make a Media Profile printout to verify that the sensors are performing properly.c. Press PAUSE and run Auto Calibrate again.13. Press the PAUSE key to take the printer offline.14. Press the FEED key several times. Each time you press FEED, the media should advance one label length and stop.15. Once the Sensed Distance value and performance is confirmed, save it to the desired configuration menu as described on page 37 before powering off the printer....

28Chapter 2 Pneumatic Control Valves And GaugesPneumatic Control Valves And GaugesAir Cylinder RegulatorNOTE: You may also adjust the cylinder delay time through the Applicator Delay menu. See “Applicator Delay Menu” on page 29.The air cylinder regulator (CYLINDER valve) is used to regulate the air to the applicator cylinder. The regulator setting affects how quickly the applicator pad will extend (apply stroke) and return (return stroke) during the apply cycle. This adjustment determines the force with which the applicator pad will contact the product. If set too high, the applicator pad could contact the product with enough force to cause damage. If set too low, the applicator pad may not contact the product. The air pressure delivered for the apply stroke and the return stroke is equal.Monitor the setting of the air cylinder regulator using the PRESSURE gauge.Air Jet AdjustmentThe air jet adjustment (AIR JET) controls the air supply to the air jet tube. Air is forced out the air jet tube allowing the labels to properly transfer over the peel bar then to the applicator pad. If the adjustment is too low, the labels will not properly transfer from the printer to the applicator pad. If set too high, the label edge will be incorrectly positioned. The air jet is factory preset. Adjust the air jet pressure by turning the AIR JET control clockwise to increase the flow, counterclockwise to decrease the flow. See “Positioning The Air Jets” on page 19.Vacuum AdjustmentNOTE: You may also adjust the vacuum delay time through the Applicator Delay Menu. See “Applicator Delay Menu” on page 29.The vacuum adjustment (VACUUM) controls the amount of air flow through the vacuum generator, thus determining the amount of vacuum holding the label onto the applicator pad. A weak vacuum will cause labels to fall off of the applicator pad prematurely. A vacuum that is too strong, however, can cause difficulty when transferring the label onto the applicator pad and the product. Vacuum is increased by rotating the valve clockwise and decreased by rotating the valve counterclockwise.NOTE: To get a vacuum on every label, every hole on the applicator pad must be covered by the label surface.Monitor the setting of the vacuum adjustment using the VACUUM gauge.

Select when using media with notches or holes that interrupt a black vertical line on the underside of the media. The top-of-form position is the leading edge of the die cut label (trailing edge of the gap, notch, or hole).The default is Disable.Gap Sensing for Smart LabelsIf your smart labels have a horizontal black bar located within each liner gap, set Gap/Mark Sensor to Gap. When you examine a Media Profile printout, you will see that the black bar provides a much higher amplitude pulse than that of any antenna, which will provide excellent top-of-form reliability.If your smart labels have no horizontal black bar located within each liner gap, you must choose between Gap and Advanced Gap sensing. Run an Auto Calibrate (page 21), then make a Media Profile printout. Choose the sensing type that provides the highest liner gap amplitude compared to the amplitude of the antenna line. If you select Gap sensing, and then see that the Media Profile printout shows very little amplitude difference for the liner gap compared to the amplitude of the antenna line, select Advanced Gap sensing instead.Advanced Gap sensing (often called transmissive) uses an LED array for the upper sensor and a receiver in the lower sensor to detect infrared light through the liner gap. This sensing has the advantage of detecting the liner gap as a positive amplitude pulse and the antenna line as a smaller, negative pulse.Save Config.Allows you to save up to eight unique configurations to meet different print job requirements. This eliminates the need to change the parameter settings for each new job. The configurations are stored in memory and will not be lost if you turn off the printer.The default is 1.Power-Up Config.You can specify the Factory configuration or any one of the eight possible saved configurations as the power-up configuration.The default is Factory.

393Printing And Applying LabelsPrinting And Applying LabelsWARNINGPrintronix has provided the necessary guards and warnings within the confines of the SLPA, but cannot anticipate each customer’s individual installation and operational environments. It is the customer’s responsibility to provide in-house safety guards to provide adequate worker safety for their respective production settings. WARNINGAn input signal from the product sensor will activate the SLPA when the SLPA is online unless it is taken offline.This section provides a brief overview of the print and apply process as well as suggested steps preliminary to printing.During power-up, the SLPA performs a self-diagnostic test and indicates if the system has any existing fault or warning conditions.Once the SLPA is online and configured (if necessary) for the desired application, take the SLPA offline before downloading labels from the host into the buffer. This will prevent any chance of having the system cycle before you are prepared to begin print operations.For information on the proper setup of the SLPA, see “Setup Procedures” on page 7.Label Application (Positioning) AdjustmentsTo apply the labels at the desired location on the product:1. Mount the product sensor on the side of the conveyor, determining if the sensor should be mounted upstream from the applicator pad (product passes sensor before pad) or downstream from the applicator pad (product passes pad before sensor), depending on the application.IMPORTANTMount the product sensor as close as possible to the applicator pad. If the spacing between the two is too wide, it may be to difficult to set the product sensor delay to position the label properly.It is easier to position the label onto the product using the sensor delay when the sensor is mounted upstream from the applicator pad.
40Chapter 3 Printing And Applying LabelsFigure 14. Return Speed Control Valve2. Use the flow control valve (located on the air cylinder) to adjust the speed of the return stroke. (Figure 14.) Increase the speed by rotating the valve counterclockwise and decrease the speed by rotating the valve clockwise.3. Set the Cycle Delay time for the product sensor using the Applicator Delay menu. (See “Applicator Delay Menu” on page 95.)NOTE: The Cycle Delay setting determines the amount of delay from the time that the product sensor detects the product to the time that the applicator pad is online. Since the label prints first, be sure to account for printing time. The longer the time entered, the farther back (closer to the trailing edge) the label will be placed onto the product. Conversely, if this value is set to zero, for example, the applicator pad will launch as soon as the label is printed.Begin by setting the Cylinder Extend time to 100 msec to begin this adjustment procedure. (See “Applicator Delay Menu” on page 95.)AAFlow ControlValveAir Shut OffValve
Adjusting The Cylinder Extend Time414. Place the product sample on the conveyor and allow it move past the SLPA. The label that is applied will be used as a reference point for positioning the rest of the labels.5. To move the label toward the leading edge of the product, decrease the Cycle Delay time. Begin by decreasing the time in intervals of 10 msec, then fine tune in intervals 1 msec. Repeat this procedure until the label is positioned where desired.6. To move the label toward the trailing edge of the product, increase the Cycle Delay time. Begin by increasing the time in intervals of 10 msec, then fine tune in intervals 1 msec. Repeat this procedure until the label is positioned where desired.If the label still cannot be positioned properly, remount the product sensor as follows:1. To position the label toward the leading edge of the product, move the product sensor upstream.2. To position the label toward the trailing edge of the product, move the product sensor downstream.3. Once the label is positioned in the desired location on the product, secure the product sensor onto the conveyor.If the SLPA cycles when a product is not in position, a background object may be activating the sensor. To correct this problem, reposition the product sensor or adjust the product sensor. See “Product Sensor” on page 197 for more information on product sensor adjustments.WARNINGInterrupting the signal on the product sensor will activate the SLPA.Make certain that the path of the applicator path is clear.Adjusting The Cylinder Extend TimeNOTE: Remember that the supply air pressure to the SLPA should be80 to 100 psi (550 to 690 kPa).1. Set the Cylinder Extend time using the Applicator Delay menu. (“Applicator Delay Menu” on page 29.)NOTE: The amount of time the applicator pad is energized through the cylinder extend time, determines how far the pad travels during application of the label. The longer the time entered, the farther the distance the applicator pad travels. If this value is set to zero, for example, the applicator pad will not launch.Set the Cylinder Extend time to 110 msec to begin this adjustment procedure.•If the applicator pad does not contact the product (if the stroke time is not long enough):Increase the Cylinder Extend time using the Applicator Delay menu. Begin by increasing the time in intervals of 6 msec, then fine tune in increments of 1 msec. A higher setting allows the applicator pad more time to extend toward the product, therefore, increasing the stroke length.
42Chapter 3 Printing And Applying Labels•If the applicator pad remains on the product for too long (if the stroke time is too long):Decrease the Cylinder Extend time using the Applicator Delay menu. Begin by increasing the time in intervals of 6 msec, then fine tune in increments of 1 msec. A lower setting decreases the amount of time that the applicator pad is extended (in contact with the product).The Print And Apply ProcessBefore labels can be printed and applied:1. Ensure that the protective guards are properly secured and that materials are clear of the applicator pad and printhead assembly.2. Ensure that you have input time values for Cycle Delay, Cylinder Extend, and Vacuum Delay (if applicable). (See “Applicator Delay Menu” on page 95.)NOTE: The applicator will not move unless a value is entered for Cylinder Extend.3. Press the Pause key on the control panel to enable the product sensor, or to allow remote signals received through the interface package option to activate the SLPA.NOTE: You may wish to cycle several labels onto product samples, to ensure proper operation of the SLPA.
434Preventive Maintenance And CleaningWARNINGPrior to any maintenance procedures, be sure to power off the SLPA and disconnect the power cord and air supply hoses unless otherwise indicated.WARNINGMaintenance operation should only be performed by a trained and qualified technician.CleaningGeneral CleaningDuring normal operation, media debris may accumulate around the printer mechanism. Clean the printhead area with the Printronix cleaning kit. Use a soft bristle brush or vacuum cleaner to dust the interior.CAUTIONNever use metallic tools to clean the interior of the SLPA.Dust the exterior of the SLPA regularly. It is preferable to use a Printronix cleaning kit to clean the exterior of the SLPA, or a soft cloth dampened with isopropyl alcohol.CAUTIONDo not use abrasive cleaners or solvents to clean either the exterior or interior of the SLPA.

Cleaning The Printhead, Platen Roller And Media Sensors45Cleaning The Printhead, Platen Roller And Media SensorsPrinthead CleaningAs you use your SLPA, the printhead may become dirty which can result in poor print quality. Clean the printhead each time you install new ribbon (thermal transfer print mode) or install new media (direct thermal print mode). Clean the printhead with the cleaning pen supplied with the SLPA or with a cotton swab moistened with alcohol.By keeping your printhead clean, you will help maintain its life.Platen Rollers CleaningMedia dust and adhesive residue on the platen roller can degrade print quality and cause voids in your label image. Clean the platen rollers at the same time as the printhead. See Figure 15 on page 44.Use a small amount of isopropyl alcohol on a cloth to clean the platen roller. With the pivoting deck up the platen roller can be rotated forward by hand to access and clean its entire surface area.Media Sensor CleaningThe Upper and Lower Media Sensors should be cleaned to ensure reliable TOF and paper out sensing. Clean the media sensors at the same time as the printhead.The Upper Media Sensor (located in the horizontal slot of the printhead cover) can be wiped clean using a soft cloth. The Lower Media Sensor, easily seen by its visible red light, is located in the horizontal slot of the media guard. Remove media dust by vacuuming or blowing air across the lens cover.Cleaning Procedure1. Set the power switch to O (Off) and let the SLPA cool for 5 minutes.2. Rotate the deck lock lever clockwise to open the pivoting deck and remove any media and ribbon (if loaded) to gain access to the printhead assembly heating element area.3. Gently rub the felt tip of the cleaning pen or a cotton swab moistened with isopropyl alcohol across the printhead heating elements (light brown area).4. Allow the printhead to dry for one minute before reloading the media and ribbon.5. Clean the platen roller.6. Clean the upper and lower media sensors.CAUTIONDo not use sharp objects on the print surface of the printhead. Be aware that the edges of the printhead may be sharp. Keep fingers away from the edges.
46Chapter 4 CleaningCleaning The Applicator PadFigure 16. The Applicator Pad AssemblyThe applicator pad must be clean to ensure that labels will properly dispense. Use isopropyl alcohol and a clean soft cloth. No other cleaning agent should be used to clean the applicator pad.Perform a maintenance check of the applicator pad vacuum chamber approximately every three months, at minimum, using the following procedures:1. Remove the four (or six) hex screws found at the top of the applicator pad, allowing the bottom pad to drop downward.2. Check the holes of the applicator pad to make certain that there are no large particles of dirt or dust clogging any of the holes.3. Reassemble, making certain that the gasket (foam tape) is seated properly before replacing the bottom pad.4. Check for leaks by covering all the holes in the applicator pad with a piece of paper. If there is a leak, the vacuum will not retain the paper on underside of the applicator. Sealing compound may be used to isolate leaks, but must dry thoroughly before the applicator may be used.Hex Screw (4 or 6)Top PadGasketBottom Pad
Cleaning/Replacing The Vacuum Generator47Cleaning/Replacing The Vacuum GeneratorAir flow through the vacuum generator creates the vacuum for the applicator pad, allowing the label to be held in place. If the label is not retained on the pad and the pad has already been inspected for leaks, then the vacuum generator should be cleaned as follows.1. Locate the vacuum generator inside the electrical enclosure, on the applicator side of the SLPA (see Figure 17). The vacuum generator housing will mark the pressure connection with a P and the vacuum connection with a V. Label the respective tubes before disconnecting them, to ensure proper reassembly.Figure 17. Vacuum Generator2. Remove the two air lines attached to the vacuum generator by pushing in on the tube fitting (red collar) to release tension on the flexible tubing. Hold the tube fitting down while pulling the tube free.3. Carefully wipe inside the tube fittings, using a small cotton swab moistened with alcohol.4. Using a low pressure air nozzle (90 psi. max. pressure) blow air through the V port, then the P port using three - 2 second bursts. 5. Reconnect the vacuum generator and test the applicator pad’s vacuum as outlined in “Cleaning The Applicator Pad” on page 46.Vacuum GeneratorAir Line (2)Tube Fitting (2)V PortP Port
48Chapter 4 Cleaning6. Check the inline vaccum filter located between the Tamp and SLPA. Replace if necessary.7. If the vacuum has not improved and all pneumatic assemblies and tubing are secure, replace the vacuum generator being careful to connect the air lines to the proper fitting.Cleaning ScheduleWARNINGAll cleaning of printer/applicator parts should be done with isopropyl alcohol and a non-metallic tool. Using any metallic tools can damage machine parts, particularly the printhead and surrounding parts.What follows is a guide for general day-to-day cleaning of the SLPA parts. To keep the machine running smoothly, adhere to the following guidelines:Table 2. General Cleaning ScheduleItems To Be Serviced Frequency How To CleanPlaten Rollers 8 Hours or end of shiftWipe with soft, lint-free cloth moistened with isopropyl alcohol.Applicator Pad Surface8 Hours or end of shiftWipe with soft, lint-free cloth moistened with isopropyl alcohol.Dynamic Brake 8 Hours or end of shiftWipe with soft, lint-free cloth moistened with isopropyl alcohol.Air Jets Daily Blow tube clear with filtering air if needed.

Calibrating The Media Sensors57Calibrating The Media SensorsDue to manufacturing differences in media and ribbon, the media sensors may have difficulty differentiating between the label and the liner or the label and the black mark. When this occurs, the SLPA may intermittently skip a label or display a fault message such as GAP NOT DETECTED / See Manual or PAPER OUT / Load Paper.Media sensor sensitivity and reliability can be improved by changing theGap/Mark Threshold and/or Paper Out Threshold values. You can change these values automatically by performing the Auto Calibrate or Manual Calibrate procedure in the CALIBRATE CTRL menu or change them manually by entering your own Gap/Mark Threshold or Paper Out Threshold values. (The changes take effect immediately within the current configuration menu.)Auto or Manual Calibrate is completed successfully when the displayed Sensed Distance value correctly matches that of the installed media. When Gap is selected, the Sensed Distance value should match the length from the trailing edge of one gap to the trailing edge of the next gap (or one label + one gap). When Mark is selected, the Sensed Distance value should match the length from the leading edge of one black mark to the leading edge of the next black mark.When you have completed Auto or Manual Calibrate, you can verify that the new values are correct by pressing the Feed key several times. Each time you press Feed, media advances one label and stops at the correct Top-of-Form position of the next label.Once you confirm the correct values, save them to the desired configuration menu before powering off the SLPA. See “Saving A Configuration” on page 67.Running Auto CalibrateYou can initialize Auto Calibrate via the Apply key (described in detail below) or via the CALIBRATE CTRL or DIAGNOSTIC menus in Menu mode.NOTE: Verify that the Gap/Mark Sensor option (Disable, Mark, Gap, Advanced Gap, or Advanced Notch) matches the installed media. See “Sensing Different Media Types” on page 52.Check that the media sensors are horizontally positioned to permit sensing of the label length indicators. See “Positioning The Media Sensors” on page 50.If you try to do an Auto Calibrate when Peel-Off Media Handling is enabled, the LCD will display CANNOT CALIBRATE / Disable Peel-Off. Before you can do an Auto Calibrate, you must select another media handling mode.1. Press the Pause key until OFFLINE displays on the LCD.2. Press ↓ and ↵ together until ENTER SWITCH UNLOCKED displays.3. Press the Apply key until Printer Tests / Auto Calibrate displays.4. Press ↵. Media advances until it can accurately detect the label length indicators and then stops at the Top-of-Form position. The Sensed Distance value will then display for one second.
58Chapter 4 System Adjustments5. Auto Calibrate is successful when the Sensed Distance value correctly matches that of the installed media:•Gap/Mark Sensor = Gap, Advanced Gap, or Advanced Notch: The Sensed Distance value is the physical length of one label plus the length of one gap, notch, or hole.•Gap/Mark Sensor = Mark: The Sensed Distance value is the physical distance from the leading edge of one black mark to the leading edge of the next.•Gap/Mark Sensor = Disable: Not applicable. If Gap/Mark Sensor is set to Disable, the Sensed Distance value will not be updated.If GAP NOT DETECTED displays, run Auto Calibrate again.If Auto Calibrate continues to end with an incorrect Sensed Distance value displayed or a fault message displayed, run Manual Calibrate as described on page 58.NOTE: The amount of media sampled during Auto Calibrate is based on the length of a label and transitions detected, without error, between a label and its label length indicators.6. Press the Pause key until OFFLINE displays.7. Press the Feed key several times. Each time you press Feed, the media advances one label length and stops.NOTE: After a form feed, the position of the leading edge of the next label depends on the type of Media Handling mode selected under the QUICK SETUP menu. Tear-Off and Tear-Off Strip Media Handling will position the label edge at the peel bar, while Continuous will position the label edge under the printhead.8. Press the Pause key until ONLINE displays.9. Once the Sensed Distance value is confirmed, save it to the desired configuration (page 67) before powering off the SLPA.Running Manual CalibrateManual Calibrate should be performed only when the values derived from Auto Calibrate fail to improve the media sensors’ ability to sense label length indicators on the installed media. You must first enable Admin User in the PRINTER CONTROL menu before accessing or initializing Manual Calibrate in the CALIBRATE CTRL menu.NOTE: Verify the Gap/Mark Sensor option (Gap, Mark, Advanced Gap, Advanced Notch, or Disable) matches the installed media. See “Sensing Different Media Types” on page 52.Ensure the media sensors are horizontally positioned to permit sensing of the label length indicators. See “Positioning The Media Sensors” on page 50.Ensure the Print Mode option selected in the QUICK SETUP menu matches the media installed. Select Direct for heat sensitive media (no ribbon required) or Transfer for thermal transfer media (ribbon required).
Calibrating The Media Sensors59If you try to do a Manual Calibrate when Peel-Off Media Handling is enabled, the LCD will display, CANNOT CALIBRATE / Disable Peel-Off. Before you can do a Manual Calibrate, you must select another media handling mode.1. Press the Menu key to take the SLPA offline and into Menu mode.2. Press the ↓ and ↵ keys together until ENTER SWITCH UNLOCKED displays.3. Press the Menu key until PRINTER CONTROL displays.4. Press ↑ until Admin User displays.5. Press + until Enable displays.6. Press ↵ to select Enable. An asterisk (*) appears next to Enable.7. Press the Menu key until CALIBRATE CTRL displays.8. Press ↓ until Manual Calibrate / Run Calibrate displays, then press ↵.9. Follow the instructions displayed on the LCD. Example: REMOVE RBN&MEDIA / Press Enter indicates that you must open the pivoting deck and remove the ribbon and media from under the printhead, close and lock the pivoting deck, and press the ↵ key.During the last step of Manual Calibrate, the SLPA will advance the media and attempt to detect the label length indicators and stop at the Top-of-Form position. The Sensed Distance value will then display for one second. The calibrate is successful when the Sensed Distance value correctly matches that of the installed media.If CALIBRATION FAIL / See Manual displays, run Manual Calibrate again.NOTE: The amount of media sampled during Manual Calibrate is based on the length of a label and the transitions detected without error, between a label and its label length indicators.10. Press the Pause key until OFFLINE displays.11. Press the Feed key several times. Each time you press Feed, the media advances one label length and stops.NOTE: After a form feed, the position of the leading edge of the next label depends on the type of Media Handling mode selected under the QUICK SETUP menu. Tear-Off and Tear-Off Strip Media Handling positions the label edge at the peel bar, while Continuous positions the label edge under the printhead.12. Once the correct values are confirmed, save them to the desired configuration (page 37) before powering off the SLPA.
