MPC3300 dark density

[GeorgeBest]

Hi,

Got a customer who print mostley A3 double sided with a lot af text and large fills with black background !
Problem is that the PCDU unit K is getting dirty very quickly, every 30K must clean the charge or even change the drum unit.

Don't know what to do about it, thinking of setting the density much lighter, but how ? (printmode)
By driver or adjusting the bias or what else . .?

someone?

Thanks in advance

It is just an opinion.....
Usually dirty pcdu can indicate the developer is weak or just the developer unit receive too much toner,
Maybe the toner is not genuine (katun) .
If you try to set density much lighter maybe your client will be upset too.

You can also play with
Check your readings of the TD sensor
Find a way to decrease the toner supply for BK
3011-002 (Executes the toner density adjustment manually).
3022-001 Specifies the toner supply time for BK in the toner supply mode [0 to 30 / 8 / 1 sec/step].
3043-008 Adjusts the time for the toner supply mode when a toner density is detected to be low.
3043-008 Specifies the belt mark generating time for checking the black toner density when toner
density is detected to be low at the toner density adjustment

agree with gkalman2004 , but first replace BK toner if it isn't genuine

First, that type of coverage should be done on a production model.

That said, try the settings in the attached. Service Program (SP) Settings.pdf
