Question about HP Officejet Pro K850 InkJet Printer
Lites are solid, not blinking. Ink in all cartridges, originals, not refills.Tried holding down power, hitting cancel button 10 times and restarting. Tried disconnecting power cable and network cable and restarting.
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.

1. Look at the indicator light on your Lexmark printer.
You'll need to replace ink cartridges when the light flashes or turns red
instead of the standard green.
2. Purchase Lexmark ink cartridges. You can buy the brand
name or purchase a generic version that is compatible with your printer. You
can shop for low cost ink cartridges from ABC Ink.
3. Remove the old cartridges from your printer. Grip the
sides of the Lexmark ink cartridges and pull it out. Dispose of the ink
cartridges in a recycle program like the one at Staples or save the cartridges
4. Install the new ink cartridges after removing the
protective tabs. Avoid touching the IC chip when installing the new Lexmark ink
cartridges. Replace the cover of the printer.
5. Allow the Lexmark printer to run a nozzle test. Print
several pages with the new ink cartridges to make sure you installed the ink
cartridges correctly. The indicator light should return to a solid green color.
