I have a vague understanding about this that I wish to clarify or learn from an experienced tech. When performing calibration such as U410 & U464 in service mode, does the voltages increase or decreases to compensate for wear & tear on certain components for copy process?? If so, which components? is there any other mode that I can use for calibration besides U410/464?

Re: Voltages adjustment for Wear & Tear.
No, this is a general question strictly about wear and tear and the changes in voltages via calibration.Comment

Re: Voltages adjustment for Wear & Tear.
From what I know 410 464 is all to do with lasers. So it's putting in more beam power or taking it away to make all colours even. The machine does compensate as the drums age by upping the charge voltage but I'm unsure which mode that would be changing but I'm not 100% sure curious myself.Comment

Re: Voltages adjustment for Wear & Tear.
In a color machine, the balance between ALL colors becomes the target and the engineers have locked down most adjustments so that even if you CAN change one, the next calibration will reset it.
Much is based on the eeproms on each unit with baseline calibration values.

Re: Voltages adjustment for Wear & Tear.
I think the way it works is that voltages are changed either up or down according to what is needed to get the optimal print. My guess is that the more pages printed on components means that the voltage will be increased to compensate for wearing of the supply items - DR, DV, belt, ect.
Back in the day, we used to adjust voltages via potentiometers to compensate for wear and tear.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment
