Try re-seating the ink cartridges and printing a test page. Those were new HP cartridges, right? Not some garbage from a ink cartridge refiller off ebay?

HP K850 cartridge problem


I had the same problem, all cartridges lights came on.
I did two things:

1st: I clean the print cartridges plugs with Q-tips, just to insure there wasn't any ink build on the plugs. If you look were the cartridges are, you will see four plugs one for each of the cartridges. Each plug has four contacts. They should be a bright metal color. If they dull in color, they have ink on them. Unplug the printer and pull all the cartridges out and gentlely wipe the the contacts with Q-tips. Re-stall all the cartridges.

Note: The cleaning did not solve my problem but its good maintenance since in was looking for a solution.

2nd: What work for me was I un-stall my printer totally. Turn off the printer then turn off the computer, had a cup of tea, rebooted the computer and re-install the HP cd disk and drivers, turn the printer back on. After I reinstall the software and put the printer back on my network, everything is working fine for the last two days. The lites are off and the HP toolbox is reading the ink cartridges status correctly. I believe that a virus change the printer drives.

Can we print with other three Color ink cartridges when Black Ink cartridge is emptied?


hi,

as u have ran out of ink you cant print anymore... you have to replace a new ink cartridge.... this is because when u print something, the colors will get mixed to print the exact color.... even if u are printing only in black, some other colors wil get mixed to produce the black color on the paper... so u need to change the ink cartridge.... u cannot run with a blank filled ink cartridge.... and the selection of your printer is very good...

thanks and regards

HP Officejet Pro K850 printing problem


Soon after I posted the problem on this site, I went to different margin setting windows and they all appeared correct. I tried another test page and noticed the printer was off. I turned it back on and it worked perfectly. I had previously unplugged the power and cable and rebooted the system several times to no avail. I also have an HP Officejet 7410 All-In-One so I didn't need the other for everyday operations, just preferred it.
