Ricoh 3245c colour calibration

[qwandy]

I have colours out of snc on 3245c and have tried auto calibration and colour registration but it does not help, is there a trick i am missing that will sort it.

Never serviced this machine but usually it has to do with dirty ID Sensors.
Try cleaning them and then do the adjustments.

Thanks, but tried this already and no joy

Here's what you're looking at:

Make sure the PCUs and Developer units are in good shape: if they're near yield replace them. Check the condition of the transfer belt, especially looking for toner and debris on the roller at the tall side of the transfer belt: the ID sensors use the reflection off that roller as part of their reference reading. If the belt is worn, replace. If the roller is dirty then remove the belt (remembering the location of all the screws and putting them back in their original location) and clean it with alcohol, or some kind of chrome cleaner. Clean the ID sensors with some compressed air and see if that also gives you a better result.

Colour issues were fairly common on this family of machines and the preceding 22xxc series.

Check the transfer belt cleaning unit they can cause drag on the transfer belt

remove it and try a copy then try calibration

And if all of the above doesn't work, you can always try this...

Many thanks, any idea what is the latest firmware, and where I can get it from?

Nearly every time I had this issue(and the copy quality was okay, i.e. no lines/spots) was one of two different causes:
1) The transfer belt was trashed, so the sensor couldn't do a proper reading.
2) The transfer belt rides on a shiny roller on the far left upper side. If this roller gets dirty, the machine will fail to reflect the sensor signal properly, and will fail calibration.

The roller is very dirty, I have taken the belt off to get to the roller but it is pitted with rock hard toner, can you suggest the best way to clean this or has it had its day?
