Sharp CE-150 printer/cassette interface questions

[sideburn]

It turns out it is the pinion gears. It’s causing the carriage to jam and so the pen mech doesn’t rotate and click the switch on the left telling it which pen it’s on. I slid the pinion gear back so it doesn’t touch any gears and manually spin the pin chamber 4 times as it was starting up and then it came up normal and paper feed and print commands worked. So now I need to either mold some gears or find the replacements. We’re there some brass ones available?
