Hello everyone,
Canon IRC3170 sevice call error E000020-0081,
When I remove the drum unit that clean
drum patch sensor I found that drum surface is damaged (see attachment).
What is reason for this damage?iRC3170 damaged drum pic1.pdfiRC3170 damaged drum pic 2.pdfiRC3170 damaged drum pic 3.pdf
upgrade system to v 14.01 or above
When an E020-0081 error code is displayed on the control panel (when the value of [P-SENS-P] hasdetected as being less than 255) while the background of the image on the drum is being checked uponpower-up or recovery from sleep mode, the machine stops operation with the bias voltage applied tothe charging roller. This leaves the charging roller mark [B] on the drum surface (Fig 1), causing blacklines in the main scanning direction.Figure 1[B] Charging roller markInstallation/Service NotesIf the symptom occurs please update the DC-Controller firmware to the following versionsimageRUNNER C3100 series: v45.01 / imageRUNNER C3170 v14.01)
Affected MachinesimageRUNNER C3100 KNF00001 to KNF11873Parts /
I concur with vigour.
Upgrade the system software before you put in a new drum, or you will lose it again.
it may pay you to strip out the machine too.remove the dev assy's and itb assy and give the machine a good vac.Also non oem toner can cause overtone so your patch sensor will keep getting dirty.

Re: Canon IRC3170 damaged drum
Check your rotary unit for any damage especiallywhere the developer is located.
If necessary replaced the rotary unit
Firmware issue needs to be addressed first/ drum line is a known problem without the update
see posted pdf above
