Question about OKIPAGE 12i Led Printer

1 Answer

Prints blotches and marks down the left edge

I have an OKI 12i that constantly prints blotches and marks down the left edge. I run cleaning pages that come out dirty over the whole page front and back but the blotches keep coming back along the left edge. In addition, it is necessary to warm the printer up for several minutes prior to printing the first page otherwise it will jam. I have replaced the drum assembly several times and continue to have the same issues. Any suggestions on how to fix.

That sounds like classic wear and tear issues. All those rollers and gears have very close tolerances and any variation out of the rang and the paper grabing and jamming starts. And that could be cause of the toner leaking. You must have a lot of miles on that ol girl and you got your moneys worth out of her. They dont make them like that anymore and I dont think you could find the parts even though that was back when they supplied parts. I asked an engineer once "couldn't they make that one gear out of metal like the rest of them?" He replied "well sure, but there wouldn't be any money in that..." You beat the system on that one. Time to start your research on a replacement I'm afraid.

This sounds like a problem in the computer program that is sending the prints to the printers....especially since it is happening in several of them.

Oki b410d printer has a new toner cartridge however it is still printing inconsistently on the page?

Open the lid. Mounted under the lid you should see a horizontal bar which is actually the laser [LED]. Once your toner cart has emitted, enough loose toner has accumulated on the laser that it can no longer draw on the page correctly. Using something soft and barely dampened with water [use a soft cotton cloth, NO PAPER PRODUCTS, no dirty rags, etc] and wipe gently from L to R to remove the loose toner. Turn to a clean section of the cloth and do it once more. GENTLY! No pressure, do not scrub it, or you can damage the laser. Close the lid and print something. You should be back to good now.

When the paper prints, the color is missing in areas. It looks like a streak mark down the page. The black ink is full color, they yellow and cyan have a white, non-printed streak down the center, and...

Inspect the rollers for dirty or damaged surfaces. Clean up any loose toner or other debris in the machine. Note: avoid touching any roller with bare skin; especially in the fuser section or the photosensitive drum in the toner section. Skin oil can cause poor print quality or premature degradation of the roller surface.

Toner blotched on printed material When printing

If the line has a 1/8" white margin on either side, clean your glass and mirrors.

If the line is all the way across your page, consult your users manual for cleaning the sawtooth electrode (open the front door and take out your waste tank, there is a green rod on each drum cartridge you can pull and hear a zipping noise) and cleaning the laser lens (there should be a cleaning wand under your waste tank, turn pad side down and insert in the gap underneath your drum cartridge)
