Black ink not working but all colors are. I Two new refilled cartridges used but neither worked. Initially it worked somewhat when the test print was run, but it decreased with each test and now is blank. I ran about ten cleaning cycles and allowed the ink to sit for 24 hours so that air can escape. Nothing worked. Any ideas? I have the same problem,colours ok but black ink not coming.
Press menu then start mono (blue copy button) then fourtimes arrow up (tel index). machine will be in maintenance mode. press 7 then 6 then 4 then start mono. machine will initialize the carts and do some cleaning cycles.
If you're outside can/us: after that press zero then nine. machine prints test print. If youre inside leave maintenance mode and run a test print manually.
if you cant see any bk the ph is clogged and cant be fixed anymore (because of wrong ink: pigmented ink will clogg the filter infront of the nozzels; use ONLY dye-ink for all colors!)
leaving the maintenance mode by pressing 9 then 9.
