1.10 E077-0001
 Description
There are some reported instances from the field where, during initial rotation after clearing a
jam at the main station and closing the front cover, the error code ‘E077-0001’ was displayed.
- E077-0001 displays when engagement/disengagement of the secondary transfer external
roller cannot be completed within 5 sec.
 Cause
Since the lever (B-E1) on the Registration Paper feeder assembly (at the main station) is not
securely locked, engagement/disengagement of the secondary transfer external roller cannot
be completed normally.
 Field Remedy
1. If the same error code appears when the front cover is closed after work, check to see if the
lever (B-E1) is shifted to the locking position; if not, shift it again. If the lever is in the locking
position, go to Step2.
Note:
If the lever is locked at the wrong position, the lower portion of the cover may not be fitted
completely although the upper portion does so. After the front cover is closed, be sure to
make sure that both upper and lower portions fit completely to the main body.
13. Refit the connector of the secondary transfer pressure release motor (M184).
14. If the symptom still occurs, replace the secondary transfer pressure release motor with
a new one.

 Description
There are some reported instances from the field where E078-0001 was displayed because the
ITB cleaner motor did not rotate. When the same symptom occurs, perform the following field
remedy.
- E078-0001 can be displayed when the phase lock signal is not detected for 500msec
(100msec x 5 times) continuously even if 2 sec or more have passed since the start of the ITB
cleaner motor.
 Field Remedy
1. Re-fit the connector at J5229S or J5229P on the ITB cleaner motor.
15. Re-fit the connectors at J1340 and J1337 on the I.T.B. Driver PCB Assembly (L).
16. If the symptom still occurs, replace the ITB cleaner motor with a new one.
Reference:
The connector at J1046 on the DC Controller PCB 1-1 is also related to the aforementioned
error code.
