Have you got it fixed yet ?

If not, are you quite handy with a Philips screwdriver ?

I have managed to fix mine by looking on the HP service forum under a post called "LJ 2840 seen as LJ 2830". Just g00gle it.

Have added my comments at the end of the post.

Good luck.

Take the cartridge out and reseat it. If you bought a compatible toner I would order an OEM HP brand toner. These machines don't work well with compatibles.

Hello

According to manual it means:

"Carousel rotation error: Replace the carousel drive motor or if the problem persists, replace the DC controller. It the error still persists, inspect or replace the engaging detection flag."

I think that you need to take it to service.

Best regards,
Zizzler

Hello,
The Magenta or RED toner cartridge should be removed and double check that you have indeed removed the pull tab located on the side of the cartridge which will remove the sealing tape off the new toner cartridge.
The YELLOW toner cartridge on the other hand if it is not new then it is perhaps empty and needs to be replaced. Another option is to remove the YELLOW toner cartridge from the machine, Tap it and shake it side to side to loosen the toner that is in it, and replace it back into the machine, this will usually make it start to work again!
Good Luck!

If you are getting a repetitive dot on the page and only blue then it is likely that your Cyan cartridge is bad.

Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
