Question about HP Officejet Pro K850 InkJet Printer
It is as if the ink levels are low, but there are no indicator lights that the
ink cartridges are low, nor are the indicators for the prints heads on .. .
What should I try first?
I read earlier that black and magenta were printing but not cyan or yellow.....HP says to gently wipe the side of the electronic band but not the bottom, I did all of the above...and the printheads carefully, no change w/ the printout from "clean printheads"...the cyan had an occasional blue line(very fine) and there was no yellow.
So I trickled warm water over the cyan and yellow printheads....then thought what the heck, got a bowl of warm water and swished the printheads half submerged. They print perfect now I have the reds, yellows, greens and all the colors back w/ the clean printhead option and printed a coupon, it was perfect.
I hope it's not a short term fix...I developed the problem when I didn't print for a long time, hope this helps someone, Cyn
BTW, I flashed a light down in the recepticle for the cyan and yellow printheads and they were gunky w/ blue and yellow gook, so I clean that out w/ a damp lint free rag....paper towels shredded and I had to carefully remove the remnants.
