I am having a repeated issue in the last few weeks where I get error 140B, “printhead not installed” even though my printer has a working printhead installed. I have carefully pulled out and reinstalled the printhead to no avail. I have shut down the printer and unplugged it and pressed the start button to reset it. This has worked a couple of times, but the printer wastes a lot of ink “refilling” the existing printhead and I only get a few prints before the error comes up again. The prints are fine, there does not seem to be an issue with clogging or anything. It seems to me that a connection somewhere is not being made and the printer thinks there’s no printhead until I do these things to try to get it going again, and as I said I only get 1-2 prints out of it before it dies again. A couple of times I just unplugged it and left it unplugged overnight and when I plugged it back in and turned it on and worked fine for a couple of prints until the error came up again. This is why I think the printhead itself is functioning fine.
I do not want to spend a ridiculous amount of money on a new printhead only to find out that it’s not an issue with the printhead, but rather with the printer. Is there a way to take the printhead out and clean contacts or the printhead itself to make it work properly?! Help! I rely on this printer for my business! I have hundreds of dollars in spare ink cartridges that would not work in any other printer. It is past the 1 year warranty. I love this printer when it works properly. Any help would be much appreciated. Thanks.
