Hey people!
Have an 1224c with a almost new (2000 prints) Developer K that after replacing 1st toner - before new developer - drops toner inside and over the other colors, blurring all prints. Mabe the development unit K, but why did it work fine untill the 1st toner replacement?
Before that apeared other issue: low density (almost white lines) in the midle of paper about 2 inches wide from time to time.
Firmware is very old (1.09) upgrade does it evitate unit replacement?
Counters are 20K on colour, 40k on black.
... And don't comeout with nuclear tests on these!... Didn't bought 1/2 a dousen new, actually some made 300k-600k and didn't disapoint me yet!
Of course when spending many days... just blow them!
Thanks in advance!
