Has anyone had a C368 that intermittently produced copies and prints that are faded and enlarged?
There are only about 32000 pages on this machine, so all consumables are well within expected yield.
It does it with both colour and grey scale. To me it could be either printhead or MFP.
Any insights are appreciated.
Thanks

My choice will be as your. I will start with PH unit.
Posting a sample would be nice for future references, though.

How much enlarged? From which paper source? Using the DF?
Have you given any thought to doing image adjustments? =^..^=

It shows the symptoms printing and copying, so not isolated to DF. It is intermittent.

I posted this for a colleague and he just sent me some samples. It appears that it stretches the image off the trail edge and doesn't enlarge the entire image. Paper feed is LEF.44017440184401944020The amount of stretch doesn't seem to be consistent either

Posting on behalf of colleague leaves you short handed without proper description.
Better wait for a while then do it right.

You can see by the images I posted what is happening. Any thoughts?

try and stop the copy cycle and see what the image looks on the t-belt, if faded on there it rules out above the belt or start swapping units with another machine to rule out a consumable causing the faded copies or prints.the stretch looks more like a registration problem

Were I to take a WAG, I'd guess that the transfer belt was slowing down. Why?:

Maybe because the primary transfer belt is difficult to turn.
Maybe because the drive coupler is jumping.
Maybe because the the clutch that drives the primary transfer belt is slipping.
Maybe because the motor is slowing.
Maybe some combination of all four.

Good point. I hadn't thought of it as two problems. Thanks for the push.

Add some color to those prints.
That would give more info.
If the registration stays ok its secondary or primary.
If its black only it could be drum?

Stretched print is something running to fast.
Compressed prints would be stuff going to slow like the paper being slow.
Except if things are running slower in relationship with something already moving that would stretch too?
All confused now.

Fuser garbing it with some vigor?

Are the print light on all colors?

Forgot to update this thread.
It turned out to be the printhead that was at fault.
Thanks for all the suggestions.
