As a general rule of thumb, if the cost of repair is more than 40% of the cost of the printer, it’s probably worth replacing.
Of course, it’s hard to know what the cost of repair is if you don’t know what’s wrong. Often we see clogged and damaged heads, and the cost to repair these issues varies. See our guide on troubleshooting ink dropouts on your printer to decide what the issue is. Then you can decide if you’re ready to repair it, or simply purchase a new one.
