Depending on the age of the model, it could be a couple of things. ***Never touch the drum or expose it to bright light*** The drum unit is bad. It's the shiny brightly-colored large roller in the center of the machine. On most recent smaller machines like this on it's integrated into the toner cartridge. Check it out. If it has toner build up on the ends, it's bad. or The corona wires need cleaning. Some machines have a small slide that moves from one side of the printer to the other which cleans the hidden corona wires. It's usually brightly colored .

Oki data c9500 belt always dirty


You will find the waste toner auger (Coiled wire in the plastic tube) is either snapped or blocked with hard toner. Its simple to remove as it just unscrews. If I remember correctly it sits under the transfer belt and runs down the back and right side of the base. Anyway clean and inspect it as that is what removes the waste toner.

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.

Hi, we have an oki C5650 and use sublimation paper through the printer. We have had no troubles up until recently when we purchased a generic magenta cartridge. The red on pictures was bleeding off and...


I cannot understand why you are using sublimation paper on an LED printer which uses toner. I always thought that sublimation printing is used with dye and not toner. Why it worked in the first place is odd. Anyway I reckon you have worn out the fuser and or the fuser is not reaching temperature which is why its not fusing correctly.

We're seeing heavy pixelation on all of our prints.


I would try going to the color menu on the printer and performing the density and registration calibration that should cure your problem hope this helps.

Prints streaks of lines with fussy & unclear colur


Yes cleaning the LED heads do make a difference. If they are even the slightest bit dirty your output will be affected. However the quality of the prints on these printers are not very good. I have 3 of them and all of the product subpar quality (right out of the box) especially with lighter solid background colors.

On card stock (especially coated card stock) you'll notice shading on the entire page. Again this happened out of the box on all three of my printers. I researched this and read that it was an effect of the LED technology.

Also if you look closely at your prints you'll notice that there are bars in your print. These bars look like there could be something wrong with the LED matrix...

I just installed a magicolor 7450 II and man what a difference. No shading, perfect picture quality, and larger banner printing (12" x 47") Of course the price tag is a lot more ($3k)

Assuming that you are using the same paper and have not changed any of the consumables you should do the following:

1. Clean LED head with lens cleaner or soft tissue.
  1. Remove the toner cartridge and give it a few shakes then reinstall it.
  2. The Toner Could be low so Change toner cartridge.
4. Make sure that the paper is not damp as this will cause fading and poor quality printing and images.
  1. The image drum may have been light contaminated so remove it from the printer and store it in a totally dark place for several hours then reinstall it.
  2. If the image drum is dirty then wipe it very gently with soft tissues, being careful not to scratch it.
  3. Open the top cover and check to be sure that each toner cartridge is fully seated and that each toner cartridge lock lever is pushed all the way back.
  4. Press the top cover release latch and open, then close, the cover.
  5. Check MEDIA MENUTRAY1 MEDIA TYPE and set as required. Do the same for TRAY2 and MPT.
  6. Check MEDIA MENUTRAY1 MEDIA WEIGHT and set as required. Do the same for TRAY2 and MPT.
  7. Possibly set the value of media weight in the menu to the next heaviest one.
  8. Check PRINT MENURESOLUTION setting and set to 600 x 1200DPI
  9. Check PRINT MENUTONER SAVE MODE and make sure this is OFF
  10. Check PRINT MENU – MONO PRINT SPEED and make sure this is set to MIXED SPEED
  11. Check the COLOUR MENU – DENSITY CONTROL and set this to AUTO
  12. Check the COLOUR MENU – AUTO DENSITY and set this to EXECUTE
  13. Check the COLOUR MENUCMY 100% DENSITY is set to ENABLE if you want a glossier black finish.
