Are you sure that all transport tape is removed from the new drum? Check the drum closely and see if there is anything that diff from the old one. If it doesn't work correct, sometimes it's stucked, try replace it at your reseller.

Hello, these printers tend to be finicky.
In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.
Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.
Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.

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.
