Question about Canon NP 6050 Copier

1 Answer

Changing the drum on a Canon NP-4050?

Basically where do you start when taking the old one out? And what do you watch out for? I can buy a new drum myself for $230 and the tech will charge me around $500. Naturally, I'd like to do this myself since we own the copier.

NP 4050 -

The door may be closed, but there is a inter lock switch that is not being closed. If you have all four paper tray, try to turn the copier off and disconnect the bottom two cassette's from the back of the copier and turn it back "ON" and see if the copier works. If it dose you have a problem with the bottom two tray's. You have a very old copier, can you do with out them? If not the switches are toward the front & it may just be knocked out of place... Good Luck...

The toner is not adding correctly into the developing assembly. 1) If toner hopper is overfilled, the toner motor worm gear splits as a result of the hopper becoming packed tight. 2) Sometimes the worm gear splits under normal use.

Canon NP-4050 printing almost completely black pages

This problem appears to be that the scanlamp cable has fatigued and become open-circuit. This can be checked by selecting A3 and pressing the START button while having the lid up. Watch to see if the light stays on all the way through the forward pass of scan cycle, it can be intermittent. Make sure that the machine is unplugged before attempting to replace the cable.The drum is definitely on its way out at that amount of copies, but can be made to last a fair bit longer with some fine-tuning.
