C280 black printing

[Barrne]

konica c280 intermitent black printing, new dev unit and imaging unit, new toner, prints 200 to 300 pages black text then nothing only color??

this copier does not give any error at all,

i have cleaned the toner path of to replenish with new toner, reconected dev unit cable, checked for errors and non there, it just fades to no toner, i have been told it might be the PH unit, not to sure on this as there are no errors.

any ides ??

thanks

Its not listed in the first version parts manual, thats probably why you couldnt find it.

The part number you have been quoted is however correct.
