Oki C5300 toner "leaking" on to surface

OKI C5300 print out has "toner" blotches which appear to be from toner that has leaked out of one of the cartriges on to the belt that carries the paper through the printer (same location on the paper as the belt).  Once we clean the belt off, the first few prints are clean - after that, more toner blotches - please advise

1 - take out all consumables
2 - use canned air to clean interior (do it outdoors)
3 - spray toner cartridges to remove stray toner (keep them connected to the drums, do not separate)
4 - make sure toner carts are properly installed and locked down

Why is it putting black blotches of ink all over the paper?

You might have a leaking drum. Or toner might have spilled in the printer during a cartridge change. if you have a HEPA Vacuum with a soft bristle brush lightly vacuum any spilled toner in the printer and try again.

Wide yellow line and blotches in blue background

he poor quality in OKI LED color printing might be fallen on one of the following problems:
- Toner is almost running out
- Drum is scratched or its life almost terminated
- Belt is scratched or its life is almost terminated
- Fuser is scratched
- LED Print head is dirty.
Depend on the knowledge and experiences of each person, the solution is solved easily or takes much time or much labor as well as money This is my suggestion that I have learned from my experiences on OKI C3200, C5300, C6100, C330 that I own:
- First, you should have extra printer accessories suchj as toner and drum cartridges (Y,B, C, M) and fuser, belt for reservation. I think you should have them since someday your printer must need them after they reach to their life limitation.
- Test one after one with the good ones. First testwith tonner cartridges. If the test is OK then continue to test drum cartridges. If it is OK then test fuser and so on. Finally if it is OK, then you must look at the LED Printer heads.
Below is the bad print-out:

Prints blotches and marks down the left edge

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.

How to do borderless printing with an oki c5300

You cannot do borderless printing with a toner/fuser based unit.
The printer needs a paper grip area and cannot print to the edge due to the fuser.

OKI Laser Printer C5300 printing on paper with black flecks

IF you are using after market black toner then we found your problem. Putting a real toner on now wont help cause dodgy toner is now in the drum, you need to replace Black drum and use real toner. If you are using gen OKI toner, then just replace the Black (K) drum.

Clean led head and these printers dont need a teco, they are designed for wearing parts to replaced by operator ie Transfer belt, fuser, drums and toners.

OKI 9800 with "342" error code

problem might be with toner recycle coil which runs around the back of the belt unit. as the cyan unit is the furthest down the line if any blockages occur it can back up and lift the drum unit up. check the square opening of the recycle unit on the cyan end. Make sure you change waste toner unit when prompted or you might break a gear (big job) Karl Oki engineer
