MPC2500 dark top and bottom but light in the middle

For this reason I say that is should be cleaning more often...
Like mabawser said the problem is with that cam. I am not sure but i think it is a faulty solenoide

now you are giving him more job and prolong the his agony of going back more times to the customer to clean instead of finding the right solution. if the solenoid is the problem then make it sure that's the thing if not then find for other cause.
