Have (12) 2330dn printers and often get a message as follows: "replace missing or defective toner" on different printers. We are using geniune Dell toners and photo conductors. We can open cover and remove toner and put it back in and the message clears for awhile. Sometimes you have to seperate the toner and PC, snap them back together, put it back in printer and then the error goes away. The toner level and PC life are both good.
I'd like to add that we're experiencing the same issue. We have 4 in the office...3 are experiencing the same trouble, 1 is not. The one that isn't is using a regular capacity toner cartridge, the 3 that are have the high capacity cartridges. My theory is that it's not a coincidence.
To be honest, I didn't pay attention to what cartridge it was. Just that it's a genuine Dell cartridge. Anyway, I just ended a chat session with a Dell tech and they sent me this link for a firmware update (via usb):
Will do. But I'll report back around Friday since the error we get is intermittent. If we get the error again, we should get it by then. Also, I read the instructions for the firmware update more. The update can be installed using the printer's web interface and the firmware specifically addresses the cartridge 31.xx error.
I am having the same error on a 2330dn. We only use Dell toner, but we are also using the high yield cartridges. Has anyone else found a solution yet? We have to open and shut the front of the printer and the 31.xx error goes away until the next print job.
