    Angry MX-B201D Saying "Install Toner Cartridge" with new cartridge

    I haven't run into this issue before, so here goes. A Sharp MX-B201D. Just replaced the drum, process unit and developer. Install its used cartridge and the machine doesn't recognize it. I install a new OEM one and I get the same. I cleaned out the contacts and even tried replacing the chip on the new cartridge just in case. It just will not recognize a toner cartridge. Praying it's not the PWB. Any thoughts?

    I have had where the new cartridge had a bad chip on it causing problem like that. Try another toner if you have one to be sure.

    We tried the used cartridge that was in it when it came in, then we tried a new one off the shelf. The other tech just tried another used one, almost full, with the same result. We can't get rid of the toner message. This is a first for me with the Sharps. Thanks for the input. I appreciate any help I can get.

    Does the machine do anything? Is it cycling like it is adding toner. Is the developer unit sensor working?

    Those units are kind of dumb, I might check the reassembly, make sure that everything is lined up and seated properly. If not that then I might check the firmware, see if there's been any reported issues like that.

    Check the connector in the rear frame that toner plugs into. They can be bent out of position.

    Cool Re: MX-B201D Saying "Install Toner Cartridge" with new cartridge

    Ended up being the toner density sensor in the developer assembly. The unit had been vacuumed out without removing the sensor and static popped it. Thanks for all the replies, guys. You're awesome.

    One thing we use is

    Amazon.com: 3M 497AJM 120V Portable Electronic Vacuum Cleaner: Home Audio & Theater

    Though, truth be told $300 for a vacuum is kinda steep for a grounded setup.
