Hello everyone,My printer does not turn on at all.This is what I have tested so far and found to be good:1. fuse2. power cable3. Power SupplyI opened the bottom cover of the printer, while turning it on I noticed that the lamp on the power supply and the lamp on the card turn on for 2 seconds and turn off.I assume it is some kind of protection that causes the printer to turn off. I would appreciate it if you could help me find the problem.me find the problem.
