Intervention messages

Intervention messages display in a separate message window. This section provides detailed troubleshooting suggestions and additional information about the following intervention messages:

0133 Skew error

Symptom: The forms are not feeding straight through the fuser. This error most often occurs when the form skews toward the front or rear of the printer as it enters the fuser. This error was detected by the skew sensor (Figure 91), which is located at the top of the preheat platen. To be correctly aligned, the form must be positioned so that the edge of the form is at the center of the lens of the skew sensor.

Possible causes and suggested recovery actions:

  1. The skew sensor may be dirty. Check it for paper dust or toner buildup and clean it if necessary (see Cleaning the forms input area).
  2. Ensure that the form is aligned correctly with the red line at the entry point to the preheat platen.
  3. Ensure that the tension arm is aligned correctly. The blue mark on the tension arm should be visible in the guide notch in the transfer station. If necessary, check the tension arm (see Checking the tension arm).
  4. Check the paper path and ensure that the forms are aligned correctly at the transfer station:
  5. Ensure that the forms are aligned correctly with any preprocessing devices and ensure that nothing interferes with the paper path.
  6. If a Buffer/Flipper Unit is installed (duplex mode), check that the buffer flipper is positioned so that the forms are correctly aligned between Printer 1 and the flipper and between the flipper and Printer 2.
  7. Forms jams can also cause this skew error. Ensure that the forms are loaded correctly:
  8. Some forms have a tendency to skew. Set the preheat temperature to a lower value (Printer Definition -> Print Quality) and try printing again.

0119 Upper tractor forms jam

Symptom: The upper tractor jam sensor has not sensed the passing of the pin feed holes for more than 2 inches. This error most often occurs when paper dust blocks the sensor. This error was detected by the upper tractor jam sensor (Figure 93), which is located at the upper front tractor assembly.

Possible causes and suggested recovery actions:

  1. The upper tractor jam sensor may be dirty. Check it for paper dust or toner buildup and clean it if necessary (see Cleaning the transfer station area).
  2. While doing an auto load procedure, the form may not have loaded correctly from the lower tractors to the upper tractors.
  3. Ensure that the upper tractor jam sensor and the black area on the underside of the upper tractor cover are free of scratches, dust, chads, and adhesive.
  4. If stray room light is falling on the sensor, close the top printer cover. Printing or dark colors between the pin feed holes on the back of the form can appear to the sensor to be a torn form.
  5. The forms or tractor holes may be torn. This can be caused by a clinging chad that is caught in the urge unit. Check the preprocessor to ensure that it is not causing too much resistance or drag on the forms. Also check the urge unit and buffer/flipper unit.
  6. The forms may have lifted off the tractor pins. Ensure that the tractor holes are aligned correctly on the tractor pins. Turn the Tractor Control knob as necessary to ensure that the forms are tight between the tractors.
  7. The forms are not flat and tight over the sensor. Ensure that the forms are positioned correctly in the forms input area. The forms must not twist or tear when they travel around the input guide, splicing table, and transfer station.
  8. If the jam occurs only with one kind of form, especially one that has not been used before on the printers, the problem may be form-related. Forms that are unusually heavy or light and forms that have holes or cuts are all likely to cause jams.
  9. If the forms are in a box, ensure that the box does not interfere with form movement.

079A, 0131, 0132 Tension errors

Symptom: The position of the tension arm is incorrect. The tension arm is in the down or upper position. This error most often occurs when the tension arm is not positioned correctly or you are running heavy forms. This error was detected by the upper tractor jam sensor (Figure 93), which is located at the upper front tractor assembly.

Possible causes and suggested recovery actions:

  1. The tension arm may be misaligned. The blue mark on the tension arm should be visible in the guide notch in the transfer station. If necessary, check the tension arm (see Checking the tension arm).
  2. The forms may be slipping at the hot roll. This can be caused by forms that have absorbed moisture or forms that are smooth or coated.
  3. If you are running with high preheat temperatures, or running unusually heavy forms or narrow forms, the upper or lower tension arm may need adjustment.
  4. The forms are not installed correctly or the forms are broken. A double-sheet feed can also cause this error.
  5. If the tension arm drifts up when the vacuum is turned off, there will not be enough vacuum to hold the form correctly on the preheat platen. If this is the case, call for service.
  6. If the problem occurs after an NPRO, the upper tractor jam sensor may be dirty. Check it for paper dust or toner buildup and clean it if necessary (see Cleaning the transfer station area).
  7. If a postprocessing device is being used, it may be prematurely pulling the paper out of the fusing area. Check the postprocessor to ensure that it is not causing too much resistance or drag on the forms.
  8. When running tractorless paper, the lower pressure roller may not be engaged.

D720 Verification mark position incorrect

Symptom: The printer could not read the verification marks at the expected location. Side verify marks are small toner marks printed on the leading edge of the form; the marks are used for front-to-back data synchronization. This error most often occurs when dust blocks the sensor. This error was detected by the Toner Mark/Side Verify sensor (Figure 89), which is located at the back side of the splicing table in the forms input area.

Possible causes and suggested recovery actions:

  1. The forms may be misaligned. Check the forms alignment on both printers. The perforation must be aligned correctly. See Checking forms alignment.
  2. The toner mark/side verify sensor may be dirty. Check it for paper dust or toner buildup and clean it if necessary (see Cleaning the forms input area).
  3. The rear paper-edge guide may not be adjusted correctly for the size form you are using. See Adjusting the rear paper-edge guide and Dual Toner Mark/Side Verify Sensor.
  4. Examine your forms. Preprinted marks within the carrier strip as well as some colored forms can cause this error. If you are using any of these forms, disable verification checking. See Verifying synchronzied duplex printing for tractored forms.
  5. Verify the print quality of the verification marks. Check for light or smeared print.

0134 Fuser wrap

Symptom: The forms are wrapped around the backup roll or there is a forms jam in the hot roll area on Printer 2.

Possible causes and suggested recovery actions:

  1. If there is also a stacker jam, the forms may have been pushed back into the sensors. Correct the stacker jam, and ensure that the folding direction of the forms is set correctly in the stacker and with the Forms Set switch. If you need to clear the stacker jam, see Clearing a forms jam in the Stacker for instructions.
  2. If this error occurs while doing an auto-load procedure, ensure that the first sheet is folded over the second sheet. If the leading edge of the form is curled, this would prevent it from feeding into the scuff rolls.
  3. If the forms are wrapping around the hot roll, the fuser oil feed rate may be set too low. If they are consistently wrapping around the hot roll, you may need to set the oil feed rate higher.
  4. Light-weight forms with heavy print density or large areas of solid area fill may stick to the hot roll if the oil feed rate is too low or if the oiling system has failed.
  5. Light-weight or slightly damp forms can cause wraps.

0093 Input loop paper jam

Symptom: The printer is not maintaining the correct paper length on the input loop. This error was detected by the feed loop sensors (Figure 92), which are located in the forms input area below the transfer station.

Possible causes and suggested recovery actions:

  1. The input feed loop sensors and LEDs may be dirty. Check them for paper dust and clean them if necessary (see Cleaning the forms input area).
  2. Check for paper jams in these areas:
  3. Check that both pinch rollers are properly contacting the drive roller on the urge unit.
  4. Ensure that the forms are aligned correctly with any preprocessing devices and ensure that nothing interferes with the paper path.
  5. If a buffer/flipper unit is installed (duplex mode), check that the buffer flipper is positioned so that the forms are correctly aligned between Printer 1 and the flipper and between the flipper and Printer 2.

0161 Stacker jams

Symptom: This error can be caused by a forms jam in the stacker. The error was detected by the stacker jam sensors Figure 94, which are located in the stacker area above the stacker table.

Possible causes and suggested recovery actions:

  1. The forms are not folding correctly. The forms stack should lie flat without bowing between forms.
  2. The Forms Set key on the printer operator panel is set incorrectly. It should be set to match the fold direction of the fold perforation that is on the lower transfer station tractors. About the printer control panel describes how to set the Forms Set key.
  3. The Forms Width lever or Forms Length lever on the stacker control panel is set incorrectly. About the forms exit area describes how to set the levers.
  4. The stacker table is not lowering correctly. Check the stacker area and remove any obstructions.
  5. The stacker jam sensors and mirrors may be dirty. Clean the six stacker jam sensors and the two mirrors with a soft dry cloth (see Cleaning the stacker area).
  6. The forms are out of specification.
