Double page copies and CRU Error

Hi, I have a problem where incoming faxes are printed twice (90% of the time). I have an error on my LCD that says "CRU fuse Error" which i dont find an explanation for in the technical manual. When i print out a system data list it says there on top "CRU PRINTS =2? I dont know how to change this or if this is the reason for the double printing. I'm not even sure what CRU actually stands for because it doesnt mention it in the manual. Any help with be greatly appreciated.

Re: 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.

Re: 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.

Fax will not print: I connected the fax machine and plugged it in. It sends faxes OK. When a fax is sent to it, nothing comes out. The sending fax doesn't receive an error message, seems like all went...

Does the machine print anything? such as a directory or print when making a copy? I rather suspect it does not. When an incoming fax is recvd does the paper get pulled in and come out blank? If so your problem is with printing (or lack of it). Perform head cleaning. Also make sure the black cartridge still does not have its deal stuck on it. Post again if you still have problem.

Fax can do copies and send but not able to receive incoming faxes. Did several tests. Modem picks up but doesn't transmit data. LCD screen does not indicate any trouble or alarm.

It's possible that somehow the incoming faxes are going directly to memory and not printing. If there was a Tx issue, you'd get an error message on the LCD screen or a printed out message. Not knowing what kind of machine you have, I can't give you instructions to print from memory but if you check your manual, you should see instructions to both print from memory and set the fax to print automatically.
