Canon NP 7130 F copier
Copies
Hello,
Enter in service mode and do an cartridge adjustment. Maybe the toner is not uniformly distributed in cartridge. Also you can search on internet for service manual, this may help you a lot.
All the best !
Will not copy.
If its giving blank copies there was a ploblem with the laser shutter on these. If so it needs to be taken to authorized Canon repair facility for repair. Maybe still under warranty.
How do I change the drum to a Canon NP 7130 Black and White copier?
Could be the drum or the fuser causing your problem. To replace drum you need to open the machine by hitting the gray release latch on eft ide of machine to clamshell it open. Inside you will see th toner cartridge/ dv unit on the far right and immediately to the eft of that is the drum unit. You need to release the dv unit by turning a lever before removing the drum unit. Should probably call a tech to do this for you so you dont scratch or damage the drum. Drum life on that model is about 30,000 prints. Whats the meter reading on that copier?
