Re: screw mark problem C1060

Is it happening on all colors or just Magenta? How many total prints on the magenta developing unit?

Re: screw mark problem C1060

That problem will happen if the machine sits for long periods or if the customer does nothing but continuous low-coverage printing. Humidity also plays a factor, as well as the levelness of the machine.

You can fix the problem by increasing the developer conveyance speed. Change DIP SW 46-4 to a '1', then do Gamma Automatic Adjustment. Also change DIP SW 44-5 and 44-6 to a '1'.

Since your current developer is depleted, it'll take a few hundred copies for it to get toned back up after performing the above settings.
