Malfunction c-2552 konica Minolta c252p - Konica Minolta bizhub 250 All-In-One Laser Printer

Hi, C-2552 on the bizhub C250 means the sensor that measures the Cyan toner level has detected it as abnormally high.
It's likely to be the Cyan Imaging Unit has failed. But try this first..
Remove the Cyan Imaging Unit, give it a gentle tilt (45 degrees or so). Tilt it backwards and forwards a few times, then refit.
Hopefully the code will be gone.
If not, it sounds like the Cyan Imaging Unit is faulty.

Regards

Tam
