Question about HP LaserJet 2840 Printer
The carousel gears are out of sync - "off a tooth" and have to be realigned. i spent 3 days last week fixing this problem - it's quite a job, to say the least. my question - if you ever check for this answer - is: what were the circumstances when the problem first occurred? just after replacing a toner cartridge? if so, was it recycled cartridge?

Follow each of these steps until the problem is resolved:
Print a printer self-test by holding the power button down with a pencil and opening and closing the top cover four times.
Check the nozzle self-test pattern in the self-test print out. If one or more of the solid rectangular areas are missing, an electrical contact problem may be present.
Remove and then reinsert the print cartridge(s) into the printer.
Print the document.
If the problem persists, follow the steps listed above for cleaning the print cartridges and print cartridge cradle.
Try printing again. If the problem continues, replace the print cartridges.

It seems simple enough, but this is one of the most effective ways of fixing printer cartridge error. Mostly, printer cartridge error occurs when the printer head is unable to identify the cartridge properly. And the basic reason behind this is that the cartridge is improperly attached. To reattach the cartridge, turn on the lid of the printer and then remove the cartridge from the printer head. Check the cartridge to make sure that there are no scratches or other damaged parts that can contribute to a printer cartridge error report. Take note that the cartridge should not be left open for more than 30 minutes; otherwise the ink will start to dry up and the cartridge will get clogged.
