[ Case in the field ]
Description
Since the yellow toner supply screw HP sensor (PS68) had poor contact, the error code "E025-0102" was displayed.
- E025-0102 can be displayed when the supply motor timeout error occurs. (The first 2 digits of detail code means as follows: 01 is yellow; 02 is magenta;
03 is cyan; and 04 is black.)
Field Remedy
The instruction in the service manual requires replacement of the toner supply screw of trouble color. However, before doing so, perform the following
procedure.
1. Check to know the hopper that caused a trouble from the detail code.
2. Refit the connector of cartridge motor of the trouble color with reference to the following.
- Y: M39/J301D
- M: M40/J303D
- C: M41/J305D
- K: M42/J307D
3. If the symptom still occurs, refit the connector of corresponding sensor with reference to the following:
- Y: PS68/J331
- M: PS69/J332
- C: PS70/J333
- K: PS71/J334
14.3.7.10 E061-0001/E061-0015/E061-0009: Potential Sensor PCB is faulty

[ Case in the field ]
Description
Since E061-0001/E061-0015/E061-0009 was recorded as an error history, the Potential Sensor PCB was replaced by a new one for solution.
- E061-0001 can be displayed when the potential is 20V or less during initial rotation at image formation.
- E061-0009 can be displayed when at potential control, VL potential indicates the specified value or more.
- E061-0015 can be displayed when the laser power adjustment is not completed.
Field Remedy
1. Check the connection of the Potential Sensor PCB.
2. If the symptom still occurs, replace the Potential Sensor PCB with a new one.

14.3.7.11 E061: How to perform '0' level adjustment after replacing potential sensor PCB

[ Manual-related ]
Description
After replacement of the potential sensor PCB, using the electrode for checking potential (FY9-3057), perform the '0' level adjustment of the potential sensor,
and then mount the sensor. If the sensor is mounted without performing this adjustment, the error code "E061" may be displayed although the image density
may not vary widely.
- E061 can be displayed when the specified level of potential is missing or the limiter goes on at time of potential control.
Reference: The electrode for checking potential is used to check '0' level of the surface potential sensor.

14.3.7.12 E077-0001/E077-0101/E077-1001: Gear in Sec. Transfer Cam Drive Assembly is broken
0018-4874
imagePRESS C1 P / imagePRESS C1 / Color Image Reader-H1 / imagePRESS C1 (CUSTOM) / imagePRESS C1+ (Printer) / imagePRESS C1+
[ Case in the field ]
Description
Since the 25T/45T gear of the secondary transfer cam drive assembly was broken, the error code "E077-0001/E077-0101/E077-1001" was displayed.
F-14-52
- E077-0001 can be displayed when the HP sensor cannot detect the home position of the secondary transfer roller within 5 sec after start of detection.
- E077-0101 can be displayed when the detachment/attachment sensor cannot detect the position of the secondary transfer roller at completion of the transfer
operation.
- E077-1001 can be displayed when the theory of the sensor has changed between the HoldOn signal and the MtrOn signal (50msec).
Field Remedy
1. Check to see if the 25T/54T gear in the secondary transfer cam drive assembly is broken.
2. If the gear has been broken, replace it or the secondary transfer cam drive assembly by a new one. At the same time, check to see if the 23T/50T gear in
the secondary transfer mount assembly that engages with the 25T/54T gear has been damaged.
3. If the 23T/50T gear has also been damaged, replace it or the secondary transfer mount assembly by a new one.
