Machine was working great then suddenly started printing completely magenta across all color output. Replaced transfer belt as the old one has a small hole and same result. Is this a bad magenta imaging unit?

Re: C203 magenta completely across prints
You can borrow mine its loaded with the latest firmware.
Strong signal from the ribbon cable....WhateverComment

Re: C203 magenta completely across prints
Fixed similar issues on this model and the C252's.
Remove the controller at the back to uncover the ribbon cables.
Cut a small strip of the front with a sharp scissor to get past the old impression left on it to put fresh copper back into the connector.
Normally caused by bad HV or laser contacts.WhateverComment

Re: C203 magenta completely across prints
I've had full-color background caused by failing printheads on the cXX3 series. If cleaning up the ribbon cables doesn't work, try swapping color lasers to see if the problem moves.Comment

Re: C203 magenta completely across prints
is there a corona cleaner stuck halfway?
swap drums around yet?We know a thing or two because we've seen a thing or two.
The medication helps though...Comment

Re: C203 magenta completely across prints
There are some little clips that can be annoying, but I'd rate it as one of the easier KM machines for PH swaps. Just take your time when seating the printheads, making sure they are snugged up nicely.Comment

Re: C203 magenta completely across prints
It's a big job to swap or replace the print heads. Don't look into this too much. Replace the magenta Image unit and be done with it!
Yes image units can go all of a sudden. Bad laser would be more of blank page, no image problem, not color on page.Comment

Re: C203 magenta completely across prints
Replaced iu, same result. Full magenta page. Maybe bad ground in back?Comment

Re: C203 magenta completely across prints
Ok, if you tried another IU then you have to look at high voltage problem, bias for background, etc.
Could be a contact but I've never had to clean any on that model and I was servicing a lot of them at one time.
I could be wrong about the print head but again I was servicing a lot of them at one time and only time I replaced PH's was for laser error codes, never for full color background. Especially the older serial #'s with old style PH's, cold really affected the motors not quality. There was a bulletin to change setting to make them spin longer in cold weather or something like that.Comment

Re: C203 magenta completely across prints
Ouch! At least they changed design and made easier to open rear cage on newer machines. Actually the main thing and PIA is getting the rear cage out of the way. I disconnect only the connectors needed and let cage hang to right. Of course you have to remove fax, hdd, some covers and a lot of screws first. Once you have cage out of the way HV pwb is right there.
Let me know if you need anything. Have several working machines.Comment
