MPC2503 slightly red glow . . .

[GeorgeBest]

Hi,

When making a color copy or color print there is a minimum slightly red glow/background !
I've already changed the PCU and the Developer unit Magente for a new one.

Still, but less then before, a small glowing red background in the color mode.
Mostley this sort problems are solved by changing the M unit, not now . .

Any Ideas? High voltage? ITB? Contacts?
soon will be visting customer.

Thanks in advance

Is it an even background?

When replacing the PCU did you re-attach the rear plate? If this is missing it can cause a background to appear.
Also, make sure you enter the coefficient of the new drum in SP2-005-237.

It is easy to miss these two, even after fitting these drums a hundred times.

If the problem persists between different drum units, perhaps a shading error?
Make sure the white reference, optics, and laser are cleaned. Perform a memory clear on Printer Application, to reset the ACC, then re-perform the ACC and do a test print. If that looks good, do the same with the Copier Application, but make sure you take note of their Copier settings first.

If you get a chance, either print off the Printer SP colour test pattern, or get the customer to, and post it here.

Did not do the SP2-005-237 input, easy to miss as you said
But I've heard that when you change the drum together with the developer the input is not necessary?
