Xerox 3030 stuck at " adjusting copy quality"

[copytech200X]

clean up illumination sensor first then check the value reading .

[Polo-022]

Adjust exposure first to "5", using the appropriate Test Pattern for sure. (Routine 9-21-3). Do this adjustment as per Service Manual, NOT superficially!!
Replace illumination sensor if problem insists, especially at warm-up. It is a well known fault since '96.
(Check toner cartridge drive gear 7E16341, it has a D-shaped hole, if copier has too many meters..) Copytech200X points to the right way!!
