MP C305 Light Copies

[slimslob]

Here is a scan of what I'm getting.

Looks under toned, possibly crap paper and crap after market supplies.

LOL WTF is a drum power supply? I know the HV board and never had any probs with that so far so I'd say this was a bullshit answere. Trust me, run force toner suppy for all colors a couple of times again and check the result and check the converage of a full bleed pattern on the drum surface after interrupting the print.

I have had them fail. When they do you get the opposite of light copies. You get full page coverage.

Couldn't agree more, got it working ran a forced toner supply then initialized the toner dens sensors.

[slimslob]

Yes cleaned the ITB density sensors.

What did you use to clean with?

[Maged_elagamy]

Did you perform Forced toner supply as advised ?
if you did so and still same problem
try to put some toner manually in any development unit and print a test page
if it get any better then i had a bad news for u

I have ran into that problem as well on both a 305 and 306 and it turned out to be the paper that was the cause, but there is a workaround as well that at least works on those two machines and that is under maintenance in settings there is an option of how it should treat normal paper or something like that and there are two modes, switch to the other.

I have a MP C305 that is producing light copies, when running a test page the issue shows up in all 4 colors and they appear to be blotchy as well. This issue is common to all 4 drums so it has to be something involving the ITB or transfer roller, I have replaced both. Perhaps a voltage issue? Thanks!

Common issue on this old model.

Make sure ALL the firmware is the latest.

Also does it improve if doing a duplex print?
