I have a Canon PC850 B/W Copier
I was copying on some light weight card when
the toner started to produce very light cards.
I replaced the toner, I adjusted the dark and light controls on the copier but it did'nt make any difference, there is no error code in the display.
I've tried every thing I could think of but nothing worked.
I will appreciate it if you can help me.
