Trying to replace toner in a savin 9922dp. install the toner cartridge, copier runs like it is loading the toner but then the error message to replace toner appears again (over and over)

remove the used bottle. Turn off the machine. Turn on the copier and follow the directions. If it does not work, turn it off again, put in a new bottle then turn on.
If that doesn't work, turn it off and try to get a refund on your new bottle of toner.

that would be a machine malfunction already try to see the entrance of the printer near the ribbon if attached correctly maybe some small parts have been malfunction near the cartridge slot

I hate to say it but switching it off at the wall waiting a minute and then back on sometimes resets its little brain.
I trust the toner cartridge is all correct for this model.

Bad toner pump

Please make sure that the toner tape is pulled from the cartridge or try a new black toner cartridge.

I’m happy to help further over the phone at https://www.6ya.com/expert/eric_7148ad2a373711a3

If you are not using original manufacturer's replacement toner cartridges, this could be your problem, and it will not resolve. The printer and cartridge will not "talk" to each other, therefore giving you a false reading. If this is the case, you should still be able to print normally, but you will not know when you run out of ink until you actually run out, akin to a broken gas gauge in a car.

The bottom left portion of the display gave the error message:
Waste Toner Bottle 1 Almost Full. Please call service.

They were still able to print, however this message would not go away.

To Fix:

Power down the printer using the normal shutdown method.

Open the top front door.

Remove the cover directly below the 4 toner cartridges.

The removable cover below the toner cartridges is actually the Waste Toner Bottle.

Bring this to the dumpster.

There is a round, clear-plastic tab on the underside of the "bottle". Remove this.

Shake the bottle around over the dumpster. Continue until all the toner has been removed.

Push the clear plastic tab back in place. Wipe off all toner residue before putting it back into the printer.

Put the waste toner bottle back into place. Power on the Savin. Confirm the message no longer appears and that users are able to print.

Parts availability ended for this machine Jan of 07, now is a good time just to chuck it.

i would suggest make sure the toner is the correct type, make sure when you install the cartridge it is tilted a little so toner will be towards the cap.
change your photoconductor unit.

have you tried another toner cartridge? eyo7 [email protected]
