imagerunner 2800 wavy

[copicatt]

I'm attaching a test print. Said it's been doing this about 2 weeks. Not the scanner because it does it on prints and reports. Only does it about half the time though. I've never had a laser problem on one of these and I have several out in the field. Maybe do a clear and reinput? THIS IS COMING OUT LTR-R!

Laser scanner motor control ?? imageRUNNER 2200 / 2220i / 2220N / 2800 / 3300 / 3300i / 3320i / 3320N The image made from the glass and test prints are wavy from the lead edge to the trail edge. click on pic------------------- replacing the Scanner Assembly correct the wavy issue.

Thanks for the info. That example looks almost identical...

Argh! Replaced laser 3 days ago, customer says it is still doing this off and on. Thought it was resolved. Any ideas? Is the BC PCB included in the laser unit? Can't tell by the parts catalog..........Thanks in advance. I'm stumped!

99% is laser assy.Maybe two bad laser units?.Can be a grounding issue but never see on this model.Try with D CON-CLEAR.

Yeah, my thinking too. Just can't see two bad lasers doing the exact same thing. No codes or anything. May do it 3 out of 5 prints. spotty. started running from tray 2 and no problem after 30 pages. I told them to use tray two till morning and I will check back. I know, there's no explanation to that, lol. Got to thinking............ maybe I put the bad laser back in?

Re: imagerunner 2800 wavy

Nope, just confirmed I didn't put the old laser in. I have the old one in the box.

u need to check your wall voltage & voltage supply to Laser > must be constant>no fluctuations-

u could have a grounding issue inside frame/

do a wall check first > especially NET>GD= should be 0v > 0.5v nothing higher

will check that. that crossed my mind and should have done it on site, but got to thinking too deeply........Might install a conditioner that i have to see if that helps too.....

Since voltage checks seem ok.........I'm leaning like tekcat towards it being a grounding issue inside the unit also. Not common on this model but---- for example----the 3570/4570 copiers have somewhat similar issues if the reg. roller ground spring deforms. I could be wrong and I don't think this will fix your problem but I think I dimly remember that one time for us -----replacing the drum unit fixed this issue once on a IR3300. Good luck & please let us know what fixes it.
