Question about HP LaserJet 2840 Printer
This happens occasionally with after-market (refurbished) cartridges. Sometimes the people rebuilding the cartridges forget to replace the microchip on the cartridge that resets the copy counter. Most reputable re-manufacturers will send you a replacement cartridge if this happens.
It could also be a carousel alignment or sensor issue inside the printer - if this is the case you will have to call HP for service.
Whatever you do, make sure you do not try to manually rotate the carousel to change out the different cartridges - each time you want to change a specific color, close up the printer first and then press the carousel rotate button that's directly under the ready light, keep pressing until the display says that it's rotating to the color you want, then open and change that color, repeat for each additional color.

SOURCE: Black Toner replaced
This is what happens when you also do a refil, but the advice from the refill people is to ignore the low ink warning as it will print happily until the point that the next message comes up which is that you need to replace the toner. Effectively this is to do with teh chip in the cartridge thaht tells the printer that it is low and unless you buy a new cartridge you will still get the low toner message but it is safe to ignore.
