Epson Epson LQ 850

Epson SC-850 Black ceased to work

My Stylus 850 has a problem. When I try to print everything works, but no black ink comes out. I replaced the ink cartridge to no avail, cleaned the heads, and nothing helps. Could this be an electronic problem?


Could be a bad head. What did you do for cleaning? Did you just do an ordinary head cleaning from the control panel, or did you try our head cleaning kit?

Would a head cleaning kit fix such a serious issue? It seems doubtful that a dirty head alone would cause zero ink flow.

I like your first idea, a bad head. Are these easy to come by and replace?

The head is a bit of a nightmare to replace. I've fixed quite a few of them that had no black at all with the head cleaner. Just had a 740 yesterday with no black. One shot of the head cleaner and it came back 100\%. I don't claim it will work everytime. I had a 600 last week that was fed a diet of refill ink and was left to sit for months. It resisted all efforts. Got about 10\% of the black to print but that was about it.
