OKI c5100 Printing GREY instead of BLACK.

I just replaced my black drum and had to replace my black toner cartridge because all the toner was lost in the old drum. Used genuine OKI toner because I used to have aftermarket toner (From tonerking-ebay). Thought that would solve the problem. But still instead of printing black it comes out as a shade of grey. Please help.

Re: OKI c5100 Printing GREY instead of BLACK.

Check density control in COLOUR MENU is set to auto and exucute auto density in same menu, clean the led heads on the lid.

In MAINTENENCE menu you can increase paper black setting (ie+2).

If any of your non gen Toner got mixed in the new black drum then this is the real issue.

If paper has moisture in it toner doesn't stick as well, run it threw twice (first time it dries out) to confirm it is not a moisture issue

Re: OKI c5100 Printing GREY instead of BLACK.

Not able to print a status page. Tried holding down menu 5 sec and no output. I searched the menu and am not able to find how to print status page. I did print out a demo page and the black is great but when i print out text (like the entire menu map) the black is grey. Let me know if there is anything else I can do.

OKI C3400 printer keeps saying

Okay, I had the same problem with my C3300. I phoned the people i purchased from and this is what fixed it for me:

looking directly at the printer:
-open printer
-remove drum in question (the drum is what houses the toner cartridge) in my printer it is black.
-look on the right side of the drum & there is a little (approx 5mm x 5mm) hole that has a little panel that opens- push this up to open it.

-replace drum close the top and try printing.

I had to do this 2 times before it worked, but it worked.

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 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.

OKI C5100 only printing cyan

I need to know if the test page that the unit prints as "Demo Page" comes out fine. If this is the case, your problem is within your application (software) or computer connection (check all cables). If this is NOT the case, I'll need to know more about your scenario. Operating system, type of connection (USB, parallel) and what are you trying to print. I'll be waiting.
