HP LaserJet 2840 Printer. The yellow cartridge flashing?

Did you remove the sealing tape? 5. Remove the new print cartridge from its packaging, remove the orange cover from the print cartridge, and then pull the orange tab straight out to remove the sealing tape. 6. Squeeze the blue release levers on the print cartridge, holding it with the roller facing you. Lower the cartridge straight down into the carousel until it is firmly in place. 7. If you need to replace another cartridge, close the top cover and the scanner assembly, press ROTATE CAROUSEL, and then repeat steps 4 through 6. http://www.hp.com/ctg/Manual/c00292207.pdf Other ideas https://www.google.com/search?q=Hp+laserjet+2840-yellow+cartridge+flashing ..

2840 Memory Cards not recognized

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.

My printer Hp Color laserjet 2840 is given an Incorrect yellow initially, after i bought the catridge it is telling me of 52.4 error how to go about it.

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.

54.2 ERROR


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,

Magneta Color (Toner) and when I print, the Magneta color does not print. Even on supplies status page, the yellow color section at the bottom is blank where the yellow color should be printed. How c

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! Rich Lilja
