Sharp UX-B750 won't automatically answer calls.

Replacement cartridge: SHAPR UX-C80B

my fax machine code is Fax-L120 and the earer is it is not recive and send the fax and there is also say R on the screen the other options are as it is.

You have one of these problems:
1. You are out of in and need to replace the print cartridge.
2. You have run out of printing paper.
3. You have a paper jam.

Once the problem is identified and corrected, the fax will automatically print the memory pages.

The machine is not identifying the cartridge properly. Attempt to reinstall the cartridge. It just may be installed incorrectly.

You can also put the machine in serves mode by unplugging the power from the machine, press both the the copy/help and the stop buttons at the same time, hold them and plug back the power until you see TF662B service mode.This also works well with refill cartridges. YJ

I do not know what the error code means but try this http://www.sharpusa.com/global/ContactUsProdSupp/1,1878,,00.html

They should be able to fix your problem

There's some kind of a chip chip in the catridge that notifies the printer that the same cartridge has been refilled. to get around this check keep atleast 2 or 3 empty cartridges, refill and cycle them. That should do the trick!

Did you get any help with this issue? My machine is giving me a "cartridge error"...I can't seem to get it fixed.

here is the manual
