I have a canon ir c9075 replaced the drum and developer after now I have no yellow. Any ideas?
Did you do a full initialization of the developing unit? Toner stirs and all that jazz??
Yes we did.
Check to make sure that the DV and drum are hooked together properly. The latch on both sides must be secured properly. If not, the drum will not make proper contact with the DV unit.
Also, make sure that the DV unit is connected properly. if the harness is disconnected, this can also lead to improper color transfer.
Was the ITB serviced? Make sure that the ITB is making proper contact with the secondary outer transfer roller.
Check the transfer belt charge roller for that color. There are some plastic thingys that bend or break and the charge roller is away from the belt on one side. I forget which color but one of them is a real pain because of some plastic wheels that go through a sensor you have to take off to get to it. It seems like it was yellow but I don't remember. The other tech had the problem and they brought the machine in because they could not figure it out. I think it was a different model but has the same transfer belt. We keep that small part in stock now. Sorry I don't remember the part number but if you look closely you can tell. We have a lot of 7065's but I think the parts are the same.Originally Posted by printerjohn62
Yellow developer drive belt still attatched? They can pop off................
Make copy of something yellow. Stop the copy and see if there is yellow toner on drum. If yes, ITB issue.
Anything can be made to work if you fiddle with it long enough- San Diego Copier Repair.com
Are you sure there is a developer drive belt in this model ?
Yep. Been working on Canon's since the early 90's my friend. There are several. One belt for each color. Developer drive assy in the factory parts manual Figure 270 if you want to see a illustration of them. I think there's even a tech pub on them popping off if you have access to the Canon knowlagebase online.But, that being said......my guess would be it's probably an ITB issue/belt charge roller issue for that color.. Yellow not being transferred to belt from the drum.

Those are what I was talking about. As always, Teckat is the master at providing great pics and diagrams. He used to post a lot more humorous pics in the old days though. Thanks Kat.
