Ricoh SP4510, "Set toner cartridge correctly"

[callmefirst]

On a SP4510 the customer replaced toner with a OEM cartridge and got the message "set toner cartridge correctly" , the old cartridge was generic. I tried a new cartridge out of the box and got the same message. Any ideas are highly appreciated.

If it's in a high humidity area (we have them in Aquatic centres)you may have some corrosion on the contact terminals.
Give the contacts a spritz with contact cleaner and check that the prongs of the machine side contact aren't bent or misshapen.

If the customer takes a run-up fitting the drum, then uses a sledgehammer to push it in, the contacts on the sensor boards can be bent. If they are, they can't be reliably straightened, just replace them. There are two, one for the PCU and one for the toner.

Yep, I've had to do this on the MP401 which is the MFP version of this machine and the SP6430dn which is just a wider version of the SP4510. It's not hard to do at least.

You can try bending them back, and they may even look right, but the machine will still tell you off.
