E077-0001 caused by incomplete locking of the registration feed
assembly
[Symptom]
E077-0001 may occur during the initial rotation operation by closing the front cover after jam removal of the main station.
E077-0001: Secondary Transfer Roller engagement/disengagement error
[Cause]
If the arrow [a] of the lever is located on the right side of the key mark [b] after jam removal etc. by pulling out the registration
feed assembly from the main station and putting it in, the registration feed assembly is not completely locked.
If closing the front cover with the registration feed assembly incompletely locked, the initial rotation operation starts, which causes
unsuccessful completion of engagement/disengagement operation of the secondary transfer roller, resulting in the above-
mentioned symptom.
[Service work]
Check the position of the lever of the registration feed assembly. If it is locked incompletely, turn the lever until the arrow of the
lever comes onto the left side of the key mark and lock it completely.
Check that error does not occur by the initial rotation operation after closing the front cover.
