SOURCE: Oki c5100n printing colors offset

posted by Halfwalkeer on Nov 13, 2007 Report abuse

Just replaced the color toner cartridges in the c5100N, two OKI (cyan and yellow) and one non-OKI (magenta). Now it appears that registration is completely off.

When printing an image, there is a band of yellow at the top about 6mm high, and a band of purple (not cyan) at the bottom about 6mm high. It seems that the yellow printing LED array is printing offset. I've verified this with a typical test page that shows yellow blipped up by several mm.

What the hell happened ? How can I fix it ?

Thanks -

Dean.
Comment by Halfwalkeer, posted on Jan 02, 2008 Drums are all at 34%. Please don't tell me that the drums only have a 50% lifetime on them, because that would just suck royally. When you say the problem is most likely drums, in what way ? What could have gone wrong ?

I was able to more or less fix the problem ... It took several iterations of ColorMenu->Adjust Registration followed by Maintenence Menu->Menu Reset, but it was finally able to pull the registration back into line.

I got worried at one point - after it was "fixed" the printer was powered off. Upon powerup again, registration was off by several centimeters ! Another round of the above finally "fixed" it again, but I haven't powered it down again.

It was a cheap printer. Maybe this is why ...

Comment by Soulvisitor, posted on Jan 02, 2008 I was thinking about the band of yellow being caused by cleaning blade wearing on drum, drums are garenteed by oki if over 50 %, under that one is on their own ie purchase new if having problems with them

If you can fix problem doing colour calibration then faulty drum is not likely the issue.

Cant stress how many problems are caused by non gen consumables in machines, highly dont recommend their use.

My oki c3400n continual paper jam's at the fuser. Paper comes out of the printer about 2 inches then jam's. I clear it and it happens again. Don't see any contamination on the fuser roller.


There are paper path cleaner sheets that you can get at supply stores or on line. They are sticky on both sides. They pick up paper dust from the rollers as it passes through the printer.

OKI 3530 MFP Service call: 150


Your error 150 is the toner sensor board not making contact with a drum and therefore not blowing its fuse. Remove the Main board and you will find the toner sensor board behind it. It has a lot of metal contact springs and you will most probably find one is out of position and just requires removing and refitting. If still not working the part number for the board is: 43614901 OR-Board-PRS

Good luck.

LED reads color registration error


The black along the side of the paper is usually the black photoconductor , it also could be the fuser. If the color reg says can't be preformed it probly needs a new transfer belt. If the color reg completes and the colors still don't line up it might be the laser. It also could be dirty reg sensors.

NOTE: Upon installation, the groove on the bottom of the Encoder Cover should
straddle the top of the left end of the Tractor Frame.
