After a fairly hassle-free year or so with this Epson ET-2815 printer, the cyan now won’t print at all (no lines, no nothing - printing a full cyan page just yields white). I believe the print head is fully clogged and I want to perform a print head cleaning. I need the epson-printer-utility to do so (available from here, manual here), which I did not set up when I initially set up the printer.
I have installed epson-printer-utility as instructed and run it through the terminal, but I am met with a error message saying “The printer was not found”. The printer is otherwise found on the network and configured in CUPS, and I can print just fine with it (up until the cyan channel now doesn’t work anymore).
I ran across this old post suggesting that the udev-rule is copied over to /etc/udev/rules.d, but the installation process seems to have taken care of that already.
This print head function is also available through this god-awful mobile app that I had to use to set it up, but now the app also cannot find the printer, even though I try to connect directly to the IP. I have ensured that my phone is on the same network as the printer, but alas.
This happened straight after I set up the integration in Home Assistant, but I imagine this is just a coincidence. I last used the printer just over a month ago.
Anyone have any experience dealing with this?
Thanks, I’ll try that if I can’t get anywhere with this. After a long time, now it suddenly seems to detect it upon a random retry after dealing with some other stuff for several hours, although it reports some weird values (e.g. all tanks are empty, when they are about 3/4 full for black and 4/5 full for rest). I’ve managed to start the head cleaner now at least, so we’ll see where that leads.
