I've had the following problems with my various 97 printers:
- a broken plastic gear wheel, for which a metal replacement part was suggested on this forum. Good fix!
- the white rubber wheels on the transport mechanism, which become flat if the printer is not used for a long time. If they do, the printer feed mechanism occasionally advances paper less than an entire line. I think this the most common problem, and I have not found a fix for this issue
- a broken printer head flex cable - one fellow in this forum successfully soldered it, but my attempt to do so failed. I will give it another try one day
- uneven printing. On one printer, cleaning the head arranged things, on another one, the problem remains.
- too light printing. There is one article on the forum explaining how to adjust print density by replacing a resistor, but I found that the most likely cause is just old thermal paper.
Anything I forgot?
