1.7 E061-0181

 Description
There are some reported instances from the field that E061-0181 was solved by replacing the
P-kit drawer assembly (FM2-2079) with a new one, not by replacing the primary corona
assembly. In this field case, service mode COPIER > Display > V00 showed 905V and VFF
showed 802V.
Reference:
The difference in voltage between V00 and VFF normally falls in the range between 400V and
500V.
- E061-0181 is a low laser power error, and can be displayed when the difference in voltage
between VD and VL at the maximum potential control laser power output is 200V or lower.
The meaning of the second digit of detail code is as follows: 1= yellow, 2=magenta, 3= cyan,
and 4= black.
 Cause
Since the spring terminal of the H.V. cable to which grid bias is applied was deformed,
unexpected amount of electrical charge was carried, causing the error code.
 Field Remedy
Perform the following Steps 1 though 5, which the service manual describes, if the symptom still
recurs, perform Step 6.
1. Clean the dust-proof glass.
2. Re-fit the drum unit.
Note:
Be sure to connect the connectors of the potential sensor and the pre-exposure lamp.
5. In service mode > COPIER > Display > DPOT, check the values of V00-Y (M/C/K)
through VFF-Y (M/C/K). If those values are nearly same, the laser does not go on. In
this case, check the connection of the video cable.
6. Re-fit the primary corona assembly.
7. Replace the following parts.
Potential sensor

Laser scanner unit

Primary corona assembly

8. Check the spring terminal of the H.V. cable of a trouble P-kit for deformation or
disconnection; if there is a problem, replace the drawer connector with a new one.
FM2-2079 P-Kit Drawer Assembly
FM3-4189 Primary Corona Assembly
FM2-9295 Potential Measuring Assembly
FM2-4887 Scanner Assembly

1.8 E062-0300

There are some reported instances from the field where E062-0300 occurred because of a not
securely fitted connector of the Process Unit Driver PCB.
