Question about OKI C5650n LED Laser Printer
The black prints blurry and very light on not at all This has happened a couple of times .. I would swap colors black/magenta .. print a test and then swap back and normally it would start working again. Now it is still blurry .. I have changed the toner and drum. Any ideas ? Thanks
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

SOURCE: TONER SENSOR ERROR
I have a C5100n printer that uses the same toner cartridges, etc. I have had this printer for over 5 years and it has held up quite well. Sometimes the LED sensor gets out of alignment and doesn't register the black toner correctly. The sensors are the bars that hang from the top cover. When it happens on my machine, I merely "gently" wobble the sensor back and forth with my finger and then close the lid. Generally that takes care of the problem for me. Hope this helps.

THIS SOLUTION IS FOR AN OKI C3400N ONLY
As I'm sure you know, that blinking amber light indicates that:
Assuming that is the case, and one or both of these signals an empty black toner, the problem may be in the new black toner cartridge. You can try this:
This has worked for me several times - most especially when I tried using non-OKI OEM 'compatible" toners - but no guarantees this will help you
