Crum Chip Communication error what is this?

[gwaddle]

Crum chip is on the back of the toner cartridge. I'm guessing a new toner was just installed. Sometimes you will get a cartridge with a bad chip on it. First thing I usually do is try a new toner. Or you should be able to swap the chip off the old cartridge is they still have it. I think that will work on the 277, I know it works on the smaller machines. The crum chip is, as I said, on the back of the toner cartridge. It is green and has two screws holding it on.

Use TC 16 to clear code and if a new cartridge doesn't fix it, check the connector on the rear of the machine that accepts the toner cartridge; it is easily bent if cartridge is forced in.

More than not, it is that chip on the back of the toner cart. Reset with the mentioned sim. If not. Swap with known good, then sim 16.

I generally pull out toner cartridge, check to see if there is toner still in cartridge, do reset TC 16 restart copier with door open, then reinstall toner. Have done this countless times and have only had one bad crum chip.
