Transfer roll service check

FRU	Action
Transfer assembly roll	Check the springs in the left and right transfer roll bearings. The bearing assemblies should support the transfer roll, applying even pressure to the PC drum. The roll should rotate evenly and smoothly. Replace the transfer roll assembly if the springs or bearings indicate damage or lack of proper function. Inspect the transfer roll for signs of wear, damage, or contamination. Replace the assembly as necessary. Note: Do not vacuum the roll. Note: Always check the bottom margin following a transfer roll replacement. See “REGISTRATION”

Paper picks and advances approximately four inches

FRU	Action
Reference feed assembly Backup roller assembly Paper feed gear Drive assembly	Turn printer off and remove the print cartridge and left side cover. With a left finger, rotate the main motor counterclockwise while using a right finger to resist gear movement in the reference feed assembly (located in the paper path below the cartridge). If the gear motion cannot be stopped, look for obstructions in the paper path, such as debris or damage. If the gear motion can be stopped while continuing to rotate the drive motor, one of the following units has to be replaced. Check or replace the FRUs in the following order: Backup roller assemblies Reference feed assembly Drive assembly When the reference feed assembly is replaced, it has to be adjusted. See “Adjusting paper feed alignment (skew)” for more information.

Paper jam error indication during POST

FRU	Action
Stack control flags Photo sensor	If the exit sensor flag is not resting within the paper exit sensor during POST, the printer indicates Remove Paper/Standard Bin. Make sure the flag is operating freely and correctly. Replace the photo sensor and/or the stack control flag as necessary.
Photo sensors (paper path)	Make sure the sensors are working properly. A stuck or incorrectly installed sensor causes this error. The operator panel indicates 200 Paper Jam, 201 Paper Jam, 202 Paper Jam, or 23x Paper Jam. For a 200 or 201 message, look under the cartridge. A 201 is posted if the paper stops between the input sensor under the cartridge and the exit sensor at the fuser. A 202 indicates a jam in the rear door. Errors 231, 235, 237, and 238 indicate jams in the duplex. If the printer functions correctly in the simplex, but posts these errors in duplex, check the sensor cable for continuity and replace the cable or sensor(s) as necessary.
