13DD is an eeprom error. Make sure the prcb is connected properly and that the eeprom is installed. If problem persists you may need to replace the prcb.

Description

The leading edge of paper is not turned ON (unblocked) the paper exit sensor (PS3) since the paper feeding is started.

Causes

• Transport motor (M1) • Fusing motor (M3) • Registration clutch (CL4) • Registration sensor (PS1) • Paper exit sensor (PS3) • Front side board (FRB) • MFP board (MFPB)

The registration roller is not causing the print sync issues. It is the sync clutch on the right side of the transfer assembly that is located in the right door that folds down. It is easily replaced and can be found in numerous places online.
