Why can't I use a toner and drum set from an OKI c5250 in an OKI c5200

While the drum units may appear the same, chances are Okidata puts a different chip on it that makes in incompatible. The C5200 will use drums from a C5150. The C5250 appears to use different supplies.

Trouble with Oki B6300 drum/toner cartridge replacment. Can't get back into the menu to reset the printer.

Try removing and then reinstalling. If this happens since you changed the drum and toner, then the issue would be with the defective replacement. Way to test is to reinsert the old drum and toner and if this does not happen, then you know the issue is with the new supplies

C5150: All color prints are extremely streaky and

This happened to me. It was caused by a bad "oki compatable" color cartridge. One time it ruined my drum. It was always the yellow color. Decide which cartridge is printing streaky. Remove it, bang it on the inside of a large plastic garbage can. Clean it. Reinstall it . If it still prints streaky throw it befor you ruin the drum. Replace it.

I purchased a "new" recycled cartridge for my HP 2200d. I have the correct cartridge but it prints so light you cannot read it. I put another "new" one that is also recycled in the printer and it is doing...

in the setup there are a option for more toner on print or you have to put a handle in the printer for darker prints mostally where you put the cartridge in
a recycled cartridge works allways the same as a new one

New toners and drums, but flashing amber error light - won't print now

Have you replaced the printer drums? The status monitor will tell you what percent they are at (similar to the toner cartridge status). This fixed my problem before.

Printing okay on left side but gets darker and blurrier towards right side of lines

Remove the toner cartridge and drum assembly together. Gently rock the assembly from end to end, as when installing a new toner cartridge. Then put the assembly back in place. This procedure worked for me. I'm guessing that I must have laid the toner and/or drum on its side, or perhaps upside down, when I was replacing the drum, and this was responsible for the problem.

OKI 5600 - Can you do a 'clean'?

Here's the 'secret' sevice manual:
I would also (very carefully) check for torn paper around the rollers of the imaging drum that might be rubbing the area.

Oki c5150 wont print black

First, clean the LED heads with a lint free cloth and isopropyl alcohol (the LED heads are the attachments on the underside of the lid when you open your printer; four of them for each color). Try printing something after doing that. If it's still an issue just with black, try switching the black and magenta drums/toner (keeping them locked together). The drum w/ toner cartridge simply pulls straight up and out, no switches or locks to flip. Then print a page of text; which will output from the printer in magenta. If that looks okay, then it may be an issue with your black drum and needs to be replaced.
