    thanks for the reply John....but these are indeed genuine replacement toners from Minolta....could the sensor itself have toner on it and require cleaning?

    Same problem with 5430DL magenta, seems empty but shows 100%. Only 250 pages printed with the starter toners, seems to be a common problem, no solution yet.

    I have two 5430DL printers. One is about two years old, the other is less than a month. I replaced a yellow cartridge that it said had 1% with a new one. The new one reads empty. I removed a used cartridge from the old pne that I new one... same issue. I replaced it in the old printer and it now reads empty... could it have anything to do with changing the cartridges with the printer still powered????

    All are genuine toner cartridges direct from Konica Minolta.

Also check that the printer counts printed pages right, because this can be caused by firmware or main board. if new cartridge didn't solve the problem, update firmware.

Are yo using genuine Minolta toner? Some generic toners do not replace the chip on the cartridge which tell the machine the toner levels. If this is not the case let me know. John A.

    Am I correct that both machines show wrong readings with the yellow toner? If so I would try starting with another brand new one. I have seen defective cartridges. Also you could try pulling out the cartridge and blowing out that area with some canned air. There is a sensor that reads the toner level but where you are experiencing problems with both machines and the same color I would suspect the cartridge. If this doesn't work let me know!

Error message: invalid toner yellow

If the toner is empty it will display this message and the only way I know of getting rid of it is to replace the cartridge. They do make refill kits with extra chips so you can cut the old one out and sticky tape another on. As for a clearing code I am unaware of one for this unit as the information is store in the toner cartridge.

Poor quality black output

There is a defect in the Imaging Unit of these printers....if you replace the imaging unit, the problem of the faded black prints go away. If you have less than 7000 prints, you can call Samsung for a warrantied replacement. The Imaging Unit is supposed to last at least 20,000 prints.

Printer problem

The average yield for a Q2612A cartridge is 2,000 standard pages.

Based on these statistics

Current I don't see a higher yield cartridge available for your printer. The company I work for only carries 2,000 yield as well.

Did you swap toner cartridges into this new printer?

If this is a new printer make sure all the packing material is out of the cartridge slot such as any tape, seals, or string.

Your printer should have come with instructions telling you where the packing material is.
