hi, are you a technician? Do you have the service manual? for the developer Execute [Service mode] -> [Image process adjustment] -> [Gradation adjustment]. Replace the MFP board (battery included)

Why to change DV unit?

Why to change DV unit?

I'm guessing he read on this forum that if a dev unit crashes because of over life drums to replace both units together.

If OEM parts are used just swap out dev & drum units turn machine on and good to go. Life counters & voltages will all reaset automatically. Like other poster said you should do gradation adj but not absolutely necessary.
