The toner cartridge has a chip that calculates the estimated usage of the toner and once it reaches it's capacity (per estimation), it will not print. The only thing you can do is to buy a new cartridge or buy refill toner that comes with a reset chip.

Does it say Image Cartridge or toner. Is the cartridge third party if so replace with a real Minolta cart the machine do know info on the chip on the cartridge and reject them sometimes

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

A lot of printer cartridges have microchips which make them unusable once the machine believes it to be finished, mainly to discourage refilling. maybe the chip has malfunctioned or the cartridges were used already and refilled or something. there are chip resetters , perhaps you should speak to the supplier, they may refund or replace or reset the chip for you.

Removed each toner cartridge, shake it and replace it.

I don't know if this is the real fix but it worked for me at this time..

it probably can, but see if there is a chip somewhere on the toner cartridge.

Go outside find a guy with a leaf blower on his back,give him a cold beer, (cerveza-i believe they call it) tell him your problems.

The only way to reset the toner error is to replace the counter chip on the toner cartridge. These should go for about $10 a piece. Otherwise, you can set the engine to continue on error, and ignore the blinking light. Better yet, I put a piece of electrical tape over it. You can still read the status on the LED's, but not have your wife complain about it. Saves you $40.

You need to be careful about the size of the grains in the toner. I would use toners from other printers of the same make and model series, but when you go outside them you really need to know the exact natue (specifications) or the toner you use. The chips just reset the counter that the printer tracks to tell you when you are just about out, but they are not critical for operation, but you must set the print engine to continue on error.

Did you buy a whole new drum unit, or just change the cartridge? If so, the fuse may still be blown. Also, you may need to empty the spent toner out of the old cartridge.
