Canon IRC3180 Very faint

[Kings]

Hi All,
Has anybody had a transfer roller break down. The copy im getting is very faint, just like the transfer is not present. The image on the drum and tx belt is great but is just not being transfered to the paper.
Have checked the connections within the bearing housing and the door connections but to no avail.
Has anybody had this sort of problem or can shed some light on it.....Thanks

The contact for the secondary transfer roller was not touching the transfer roller shaft. The contact should be touching the bottom side of the shaft of the secondary transfer roller.
Remove the screw and then remove the black plastic contact holder shown below

2. Verify that the contact is touching the bottom side of the shaft of the secondary transfer roller as shown in the photo below. If it is not reform the contact so that it is touching the shaft.

Also Check the Bias Tabs on the ITB Belt assembly and the Secondary Transfer Roller. They may be bent or broken and not making contact. Repair or replace the contact that is broken.

Following on from tekcat's excellent advice, make sure there's some conductive grease on either ends of the transfer roller.

Thanks a lot tekcat for the advice, but the only problem is that the pics you are showing are not from an IRC3180 but from an irc2550.The transfer roller contacts are completly different.

Ensure that the ITB ground wire is firmly attached at HVT2 and the grounding screw at the ITB frame.

The photos teckat presented are indeed from a 3080,3380.
Here's a shot of some photos.
Is this the machine you have?

Can it be possible that you are talking about 3170.

The machine I am talking about is a IRC3180. From the outside it looks exactly like the IRC3170. The earlier model to this is the IRC3100

Check the condition of the Static Roller Charge Plates. If they are deformed they may cause light copies and prints.
