Description
Since the error code "E020-0200" occurred, J1175 connector of the process unit was disconnected and then re-connected for solution.
- E020-020x error code can be displayed when the patch level of each color is lower than the lower limit at the time of ATR initialization. (0200: yellow,
0201: magenta, 0202: cyan, and 0203: black)
Cause
J1175 connector of the process unit had poor contact, the information of the patch detection sensor was not sent to the DC driver PCB, causing E020-0200
error.
Field Remedy
1. Re-fit J221 connector of the DC driver PCB.
2. Re-fit J1175 and J1235 connectors of the process unit.
3. Re-fit J1155 connector of the patch detection sensor.
4. If the symptom still occurs, replace the patch detection sensor (UN18) with a new one.

Description
Since the error code "E025-0003" was displayed, the toner rotation volume sensor (PS6) was cleaned for solution.
- E025-0003 can be displayed when an error of Bk developing assembly toner supply occurs.
Cause
Since the toner cartridge installation was performed repeatedly, cyan toner fell from the gear in the front side and accumulated on the toner rotation volume
sensor (PS6).
Field Remedy
1. Check if the toner rotation volume sensor (PS6) is soiled with toner; if so, clean the sensor.
2. If the symptom still occurs, re-fit J2005 and J2007 connectors of the DC controller PCB.
3. If the symptom still occurs, replace the DC controller PCB with a new one.

[ Inspected by Canon Inc. ]
Description
Since the error code "E025" was displayed, all the connectors of the process kit reply PCB were disconnected and then re-connected for solution.
- E025 can be displayed when the toner motor error occurs.
Cause
Since J552 connector of the process kit reply PCB had poor contact, the toner motor malfunctioned, causing E025 error.
Field Remedy
1. Re-fit all the connectors of the process kit reply PCB.
2. Re-fit J2005, J2008, J2010, and J2012 connectors of the DC controller PCB.
15.3.7.12 E045 is displayed during startup after power-on: OHT sensor unit is faulty

[ Case in the field ]
Description
Since this machine indicated the error code "E045" during startup (i.e., when the progress bar reached the point of two-thirds of its whole way) after power-
on, the OHT sensor unit was replaced with a new one for solution.
- E045 can be displayed when an OHT sensor error occurs.
Field Remedy
1. Re-fit the connectors at J212 and J221 on the DC Driver PCB.
2. If the symptom still occurs, check if the OHT sensor unit is mounted correctly.
3. If the sensor unit is mounted correctly, replace the OHT sensor unit with a new one.

Description
Since the error code "E067-0102" was indicated, all the connectors of the DC Controller PCB were re-fit for solution.
- E067-0102 can be displayed when the two detected currents of primary transfer ATVC are both the threshold or less.
Field Remedy
1. Check to see if the primary transfer roller spring is deformed or detached.
2. Clean the point of contact of the primary transfer roller.
3. Make the following selections in sequence [Service mode > COPIER > Display > MISC > DRM-LIFE] to check the setting value; if the value is around
'100', suspect that the drum almost reaches the end of life, and replace the drum unit with a new one.
4. If the symptom still occurs, re-fit all the connectors of the DC Controller PCB.
5. If Step 4 does not work on the symptom, output P-Print printouts, and then replace the DC Controller PCB with a new one.
