Canon IRC3220 Error E000751-0304

[wagsmd]

Working on a Canon IRC3220 that developed an error code e000751-0304. Cannot find it listed in the service manual. Sticks in my head it is a drum unit error, but cannot remember for sure. Anyone know what the code is for sure. Thanks.

e751-0304> BLACK DRUM
[Y=1, M=2, C=3, K=4]

E751 The connection of the drum unit /toner container is faulty.

The mark x indicates color [Y=1, M=2, C=3, K=4].

000x The connection of the drum unit (at the printer side) is faulty.
100x The connection of the toner container (at the printer side) is faulty.
010x Built-in memory writing error in the drum unit.
110x Built-in memory writing error in the toner container.
020x Built-in memory data error in the drum unit.
120x Built-in memory data error in the toner container.
030x Built-in memory writing error in the drum unit (When the number of retry exceeds the
specified value)
130x Built-in memory writing error in the toner container (When the number of retry exceeds
the specified value).

This error code indicates that an error has occurred during data writing to the internal memory of the drum unit.
It can be displayed during a Fax reception and during auto-gradation adjustment. The code will not disappear even after the cyan drum unit is replaced.

Suspect a faulty Memory PCB (FG3-2345-000):pThe Memory PCB is not part of the drum unit.

The Memory PCB is found on Page 107-1 item # 3 in the Parts Catalog.

Thanks for the info teckat. It gives me a starting point. Will start by putting in a new black drum unit as that is the fastest of the two, if that doesn't solve it, will replace the pcb. Your help is greatly appreciated. Thanks again.

I would try the toner container first.
