make sure the chip contacts arent bent on the machine side.

The cartridge chip in the c654 series is simply a fuse via a specific value resistor - if the fuse is blown the machine will not acknowledge it as new. I cant remember if its the same deal in the c452, i know the drum unit was.


I reset a K toner call on a c654 a couple weeks ago holding the chip in place with a pico fuse touching the smd fuse pads in place with 1 hand and the door switch jigged with the other. It took a few attempts but did it in the end.

Yeah i did that too. Anyway it was for the PRCB, i tested a new one and it's working fine.

The C253 range does that from time to time. Doing a system error clear with all the IU's and toners removed seems to fix it.
