I just finished repairing the printer in my HP-97.
As usual, the plastic idler wheel had disintegrated and had to be replaced.

This is the replacement wheel from the German shop. The inner diameter is 2 mm which needs to be enlarged to 3/32"

I enlarged the bore to 2,5 mm which is close enough to the actual 3/32" to fit the shaft. Luckily I ordered 3 wheels as I mistakenly bored the first one to 3 mm.

The trickiest part was putting the circlip back in place. I had to source a few replacements from my local hardware shop as I managed to lose the original one.

Next project is rebuilding the card reader. Parts are already on their way.
