The color cartridges have all been replaced in the HP Officejet Pro K850 now all the pages are printing blank?


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 Officejet 9110 can't install firmware!


The failed firmware update probably ruined the printer electronics. Have you tried downloading the firmware again? Does the printer have a "CLEAR ALL" or "RESET" button or function?

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.

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.
