The solution for your problem is to replace the black cartridge of your printer.

Do you have a new black cartridge for replacement ?

The 2840 is a slightly different sort of machine when it comes to supplies. There is a main imaging drum unit which works for all four colors, and then there of course are the 4 colors. If the unit was asking for a drum unit then you should have instaled a Q3964A. It is entirely possible that your drum unit and black cartridge both expired at the same time, in which case, you need a black toner cartridge now.

There may be a defect in the toner cartridge causing the odd behavior. You can try resetting the printer settings to factory default or upgrading the firmware. You can reset the settings through the printer's menu. The link below should allow you to download the latest firmware and it should provide instructions for performing the update.

Hp color laserjet 2840 - prints one page in color, next in black & white. Yellow ink cartridge light blinking. Says "replace supply, using black only". Yellow wasn't showing as low previously.


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.

Why is it printing only black? I have a 12A Q2612A cartridge installed


This printer is a MONO laserjet printer meaning it can only print in black colour.

If you want a fax/copy/printer that does colour you would need something like a HP Colour Laserjet 2840.

Replace Cathridge


The front panel tells you witch toner cartridge should you replace. If a supply memory error ocures then the cartridge should be replaced or exchanged with a new one. The imaging drum unit is also consumable. for "Joe 50" - there are 4 toner cartridges in the printer.
