SOURCE: Double page copies and CRU Error

CRU stands for "Current Use" and it appears on the System Data List as part of the page counters. The System Data List can be printed through the "Report" menu. Your unit is rather old and the fuser unit for it is intended to last 60,000 pages, although It can also be damaged by power failures. The part number for your fuser is JC96-01621A. This part number might have changed, but the expected price for it is around $99.00 to $129.00. Good luck.

SOURCE: CRU Fuse error

The CRU is a customer replaceable unit such as toner and drum. New ones have fuses that tell the machine that it's new. When they are installed for the first time, the fuse blows and resets the counter.

Inserted new toner it says CRU FUSE ERROR


If you have a CRU Fuse error, you have probably purchased an after market toner cartridge. If so, take the cartridge out of the machine and at the back of the cartridge you will see a small 'dummy' fuse. Take that 'dummy' fuse out of the cartridge and your printer will work. I know, it happened to me.

Double page copies and CRU Error


CRU Fuse error equates to a problem the machine has reading the print cartridge installed in the machine. It has nothing to do with the fuser.
Suggest that you change the print cartridge.
