My printer has been a work hoarse for a long time. I actually replaced the print head instead of the printer a few times rather than change the printer.
A week ago, my printer started to flash 4 times and refused to print. When you look at the cartridges, the Yellow cartridge led was off. Usually this is just a matter of reseating the cartridge but not this time. Bought a new set of cartriges. At first the yellow cartridge worked but it did not last. It is out again. As a test, I moved the yellow cartidge to the next position and it lit up.
I tried cleaning the contacts where the yellow cartidge plugs in but that did not make any difference. I could sawp in another print head but would hate to use it if the problem is else where on the printer.
Apprciate any thoughts on addition tests I could try as I attempt to troubleshoot this.
