I got a canon pixma tr4520 from a technologically challenged relative, who told me they couldn’t get it to print and it was mine to try and fix. I worked out that it didn’t have an ink cartridge in it (not even an empty), bought a replacement, and got it printing. But now it has vertical alignment issues and paper jams. I can’t afford a new printer right now, and I would love to fix this one. My fear is that I’ll sink half the cost of a new one into it between the ink I already bought and replacement parts, just for it to come out not working anyway. Is it worth my time to try and fix or should I cut my losses and start saving for a new unit?
