Question about HP LaserJet 2840 Printer
HP Laserjet 2840 only prints on right side even after replacing drum cartridge
If you are a bit adventurous and a bit patient, you perhaps can fix this yourself, and not require any disassembling. It worked for me on a similar 'carousel' unit... hp2550L.

If you look closely at the spot where a toner cartridge slips into a slot of sorts, you might see left side aligned and right side just a little off of 'good alignment' for that slot. What I did is to pull on the top of the black-plastic gear. Pull it toward the center of the printer.
There is a small, white gear at the very top of the black gear (not easy to see at first). By this pulling and bending of the black-plastic gear, you can get the gear teeth free of the white gear --- for just a moment. Just enough for the gear teeth to free-up and find their proper place. It doesn't take much.
When done, take a breadth and relax. Turn power off/on, and try it out.

Thanks for this guys! I have a Canon MF8170c (the sister printer) and was just about ready to call in the on-site tech as there was no information specific to my printer that I could find. I found a comment regarding the fact that my printer was the sister of the 2840, found this thread and I am now back in business. Thanks too for the above poster (sorry I don't have your name right now) who mentioned checking the drive gear on the toner carts... sure enough my black toner had a very tight gear and has now been replaced...Thanks again!
