=================================
how are glass copies ??



internal color > on PG10 is ok / a little over saturated , black poor,

a little offset in main scan (front to rear )

Perform a REG-CLR in Service Mode, and then running a Auto Correct Color Mismatch & Full Auto Gradation > in that posted order


lean to laser-----------------------------



run diagnostics

glass copies with my color chart are not that bad but not perfect.

Re: canon c2030 bad copy quality

sounds like you checked all the usual suspects, Is there OEM toner installed ?

That PG10 is interesting. At the top of the sheet you can see the registration is a little odd, also not sure if it's just my monitor here but it looks like the black has a small overlap onto the magenta.

I have a C2230 doing something similar that just underwent a total PM. All of a sudden the registration on all 4 colours is totally out of whack. In our case I think we replaced most of the common parts including laser and the board that drives the laser with no change.

Does the machine work okay black and white only?

...if it fails or just seems to get worse: don't forget to clean the patch sensors...

Try doing a pg6 and see if colours are lining up correctly.
If not, do an auto correct colour mismatch from the adjustment and maintenance settings. I take it you have preformed am auto gradation on the device?

Re: canon c2030 bad copy quality

The colours are completly misaligned in main scan direction, also faded. Regarding the faded print, i think you sorted something like moist paper out, am i right? Do you have a second Machine in reach? If so, I would interchange the Laser and the HVT Unit, just to be sure, while my 2 cents go in direction of the Laser Unit or its control.
