Paper feed related failure Troubleshooting procedure
The printer does not feed continuous forms from the
Front or Rear.
1. Check and replace the LF MOTOR (p.161).
2. Check and replace the ROM BOARD (p.137).
The Paper Path does not switch properly. 1. Check and replace the HCPP SENSOR UNIT (p.205).
2. Check and replace the HCPP MOTOR (p.168).
3. Check and replace the PR MECHA ASY (p.149).
4. ROM BOARD failure. Replace the ROM BOARD (p.137).
The paper feed position is incorrect. 1. Something may be wrong with the paper. Verify that the paper meets the Paper
specifications (p.13) in Chapter 1.
2. Check the SelecType settings for Page length for the front and rear tractors. See
Table 1-35. Setting values available in Selectype (p.48).
NOTE: Page length settings in application software generally override
SelecType settings, so check the application software settings if applicable.
3. Use the Panel Buttons to adjust the automatic loading position. See Top of Form
(p.45).
4. Perform the TOF sensor sensitivity adjustment (p.235). If the TOF sensor is
defective, replace the CARD GUIDE ASY (p.153).
5. If the paper feed position problem occurs with paper feed from the front, check
the FTRPE (Front Tractor Paper Empty) Sensor. If the sensor has failed, replace
the Front-Left tractor. See TRACTOR FL UNIT/TRACTOR FR UNIT (p.170).
6. If the paper feed position problem occurs with paper feed from the rear, check
the RTRPE (Rear Tractor Paper Empty) Sensor. If the sensor has failed, replace
the Rear-Left tractor. See TRACTOR RL UNIT/TRACTOR RR UNIT (p.172).
Front-feed continuous forms will not feed backward. Check the FTRPE (Front Tractor Paper Empty) Sensor and front tractor units. If
necessary, replace the TRACTOR FL UNIT/TRACTOR FR UNIT (p.170).
Rear-feed continuous forms will not feed backward. Check the RTRPE (Rear Tractor Paper Empty) Sensor and rear tractor units. If
necessary, replace the TRACTOR FL UNIT/TRACTOR FR UNIT (p.170)
