Re: mp c4500
Ok. You cant resolve this kind of problem with a firmware upgrade. Check 3222 and 3201 for the affected colour. Also when doin a force toner check if 3201 lowers down or goes up. Does the toner bottle move? Have you tried with another toner bottle?

Re: mp c4500
99% the pump. Did you change it to a brand new or used pump? If new pump, try development unit.
dont reset anything, consider this as a warning

Re: mp c4500
Wich colour i affected? Be careful with the tube beeing blocked by itb if the wrong pump is installed in the wrong place, for example placing black pump in the yellow place, its tube will be blocked by itb as it has a different angle
