A label dispenses before the tamp pad completely retracts, causing the label to stick to the tamp pad.
The home position sensor on the tamp-cylinder is not sensing the return of the tamp cylinder. Adjust the position of the Home sensor. To find this put the tamp pad all the way back to the home position and loosen the screw on the sensor and move the sensor up or down cylinder until it lights up and tighten the screw back up to keep it there.

I sent a batch of labels to the printer and nothing happens, what could be the cause of this problem?
1) The system is in Pause mode. Clear all errors and press the right arrow button (Play button) on the ECM. 2) The print engine is not receiving a Start-Print signal from the ECM. a) Make sure that the umbilical applicator cable (6150-335) is properly connected between A4A1A3J3 on the ECM and A3A2A1J11 on the chassis interface module (CIM). b) Make sure that the tamp applicator cable (6150-444) is properly connected between CIM A3A2A1J1 and the Applicator Assembly A2A1J1. The incorrect signal type may have been chosen for the Start-Print signal. Review the print engine manual, identify the Start-Print 3) Signal and set to compatible signal for current application. 4) Demand mode has been enabled. If it was enabled as a test or by mistake, disable it. 5) Demand mode is required, but the system may not be receiving a signal from Photosensor 2. a) Check the cable connection between the photosensor and connection A3A2A1J10 on the CIM. b) Clean the photosensor lens with a soft-tipped swab and isopropyl alcohol. c) Adjust and direct the Photosensor 2 at the product. d) Adjust the sensing distance of the photosensor with the potentiometer at the rear of the photosensor. *This is additional info for a previous FAQ. 6) The label-present sensor is dirty or blocked. Clean the sensor with a soft-tipped swab and isopropyl alcohol.?

The LA 1000 does not detect each product that goes by. This problem is very intermittent, and it does not happen with each product. How can I fix this problem?
Try increasing the sensitivity of the photocell. To do this, turn the small slotted screw on the back of the photocell clockwise to increase the sensitivity. (Section 4.5, Operator’s Manual) Also, verify that the light on the photocell lights up each time the product goes by, if it does not, the gain is too low, or the photocell needs to be replaced. Verify that the placement is the same for each product on the conveyor.

The label labelPrinterliner breaks when the unit feed out a label. How can I fix this problem?
Verify that the label roll is wound around the rewind assembly evenly. Also, if using Perforated label stock, replace the roll with continuous label stock.

The labels are only partially printed.
The label offset is set incorrectly. Adjust the Pitch Offset in your print engine’s user’s manual.

The labels do not track contently pass the printhead resulted in skewed print on the label.
Make sure the label material is loaded properly. Check the rewind hub and make sure that the label labelPrinterliner is rewinding onto the rewind hub properly. If the label labelPrinterliner is not rewinding properly, then the label material cannot track properly through the media path. Check the platen drive roller for wear. Platen drive roller , which will be a smooth area where the label runs. This is the rubber roller under the printhead and it should have a rough surface to it. If roller is okay then make sure media is loaded correctly and the labelPrinterliner is rewound onto the rewind hub straight. (if it isn't loaded on the rewind straight then the labelPrinterliner will rewind in a spiral pattern and the labelPrinterliner will get pulled through the system crooked).

The labels get fed onto the tamp pad crooked.
The labels are not feeding through the system straight, try reloading the labels. The Peel Blade, which is the metal bar that separates the labels from the labelPrinterliner is bent or crooked causing the labels to peel off the labelPrinterliner in an angled manner, or the air assist tube which blows the labels onto the tamp pad is bent causing the labels to be blown onto the pad crooked.

The PA/4000 prints a label, then dispenses several blank labels, and the printer displays a label error.
Remove any label debris from the label sensor and clean the sensor with a soft swab and Isopropyl Alcohol. If problem persists, then perform the Label Edge Sensor Adjustment. See Label Edge Sensor Adjustment (2.4.3) page 2-46 of the Technician's Guide.

The print on my label is inconsistent across the label and fades on the outer edge of the label.
The printhead pressure is out of adjustment, or the printhead is not Aligned properly. Perform the Printhead pressure adjustment and align the printhead(2.4 of the Technician's Guide)

The tamp pad does not tamp on every product. How do I fix this problem?
1) System is in pause-mode. Clear all errors and press >. 2) The tamp dwell time is too small. a. The tamp dwell time must be set greater than 30 ms to extend the cylinder. If the dwell time is less than 30 ms, increase the value no more than 10 ms at a time. b. Verify the operation of the cylinder with Diagnostics (Section 5.5). c. Adjust the tamp dwell-time using the procedure described in Section 5.10. 3) Incorrectly positioned end-of-stroke sensor. a. Verify the operation of the end-of-stroke sensor with Diagnostics b. Adjust the end-of-stroke sensor position. 4) Cylinder air pressure set too low. The default pressure is 25 to 30 psi. 5) The optional encoder is enabled, but the line speed report is zero ft/min. a. Check the cable connection between the encoder and connection A3A2A1J6 on the Chassis Interface Module. b. Check that the encoder is mounted so that it can report the true speed of the conveyor. c. Verify the operation of the encoder with Diagnostics. d. Verify that the line speed shown in the Information Menu corresponds to the actual line speed. 6) The label present sensor is not detecting a label on the tamp pad. a. Verify the operation of the label present sensor through Diagnostics. b. Make sure that the sensor is slightly up and not flush with the bottom of the tamp pad. 7) Certain cables may not be connected properly. a. Make sure that the Pneumatic Control Cable (6150-331) is properly connected between connection A3A2A1J4 on the Chassis Interface Module and A3A1J1 on the Pneumatic Control Module. b. Make sure that the Umbilical Applicator Cable (6150-335) is properly connected between A4A1A3J3 on the Electronic Control Module and A3A2A1J11 on the Chassis Interface Module. c. Perform the vacuum valve diagnostics. Verify the operation of the air assist valve. If the valve diagnostic fails, contact Diagraph Service for repair. 8) Cylinder rods are bent. Contact Diagraph Service for repair. 9) Cylinder airflow control is set incorrectly. You may need to increase the airflow by turning the control counterclockwise and decrease by turning it clockwise.
