Apple SilenType Issues

[tiktok4321]

Greeting VCF Hive Minds.

I recently (like day before yesterday) acquired an Apple SilenType printer - complete with interface card and a roll of unopened New Stock Apple Branded paper.

Well, I seem to have a bad pixel and the stepper motor isn't advancing the paper.

Any ideas on how to repair those two issues?

There are some older threads of people repairing them. I would go through those rather than reinvent the wheel. See what they did to fix theirs in the past.

Thank you for the suggestion. There is only one older thread that I can find that discusses any repairs and it doesn't address my questions. If you know of threads where I don't know where to look, I'll be extremely happy to peruse them.

So in a nutshell you have a dead line on the thermal head and the stepper motor.which slides the head side to side isnt even attempting to move?

Yes on the dead line. No on the side to side. The slippage is in the paper advancement.

I found a source to replace the coupler between the motor and spindle rod. Remaining issue is the dead pixel.

Shows it to be dried out rubber rings. I don't think referring to a non functioning print element as a pixel is the correct terminology however. Just nit picking.

IDK the terminology. On conventional dot matrix printers, there is a single line of 9 "pins". Thermals don't have "pins" and writing out print element seems overtly complicated. So, I invented using the term "pixel" as a resultant of the print - a dot on the paper.
