Question about OKI C5100n Laser Printer

1 Answer

Non-printing gap/line down page

On my OKI C5250 color laser printer, a 3mm thick 'white line' (i.e. non-printing gap), from top to bottom of the page, appears one inch in from the right hand side of the printed page. However, if there is an embedded graphic, the 'white line' does not appear (suggesting a software rather than hardware problem). Can any of you geniuses help me? Thanks

Re: Non-printing gap/line down page

Hey Danzo, This error is usually caused by dirt (usually toner) on the laser lens. There should be a cleaner pad somewhere on your machine (though I am not totally familiar with Oki) that will wipe across the lens. If there is no pad, you may have to find access to the lens and wipe it manually with a tissue or similar

When I print on my Oki Data printer I am getting a line down the middle of my page that is white I suppose because its taking my color away. I just changed the Fuser - how can I fix this - I have projects...

i would try and clean all the l.e.ds which are located as you lift the cover they are conected to the underneath run your finger along them and see if that helps.

Cyan drum life

Below is from the Oki web-site, here:

Cyan Image Drum with an expected life of around 17,000 pages. This is based on printing A4 sheets in a typical office environment. The image drum is attached to the bottom of the toner cartridge, and is one of the easiest consumables to replace.

Huge Margin with Kyocera FS 1000+

If the FS-1000 prints too far down the page or leave too much top margin or leaves a gap at the top of the page etc (<- for google searches). This is a problem with the felt pads on the three solenoids/clutch electro magnets that are under the right panel (2 under the engine/button board, 1 under the inner plastic cover, sometimes 4 in total on other kyocera printers). They get compressed over time meaning the metal leavers come into contact with the solenoid meaning they are released too slowly. Simply replace the felt pads with .5mm cardboard or another non-sticky non-metallic material. Too thick and it prints too far up the page.

Try cleaning the print head as described in the user guide. There could be old ink clinging to the head. If this doesn't take care of the problem, you could have a burnt element, which is non-fixable problem.

My informed guess without seeing print sample is that your oki needs fuser unit replaced. Look at orange rollers should br smooth no wrinkles.

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 -

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.
