Initially, the printer would not print black ink. So in an attempt to clean the ink cartridge carrier, I ended up getting the carriage stuck and locked into the right side. I got it unlocked by turning the gears - it would then move freely when guided. I then took the top of the printer off, took the carriage out and cleaned it out, and put it all back in. When I turned the printer back on, it rattled and I heard the carrier move left and right very quickly and loudly. The "carriage jam" message appeared. I have tried its suggestion multiple times with no resolution. The carriage will move all the way left and right when guided. I am not sure where to go from here.
It is not advised to remove the printer parts. This is done only by certified technicians. It looks like the encoder strip is damaged, this is a hardware failure.
