HP Thermal Printer Paper Advance Repair (Additional hints))

[John Garza (3665)]

Looks great Hiwi!

You are correct about the low tolerances. You are not making one for mag cards. I have repaired several Topcat printers in years past by just 'eyeballing it' and slicing tubing by hand with an X-acto knife. Never had a problem.

Though when I used to repair card readers with tubing (that is, back when the manufacturing tolerances were good. Now they are not and you frequently get a batch with inner and outer diameters being non-concentric leading to irregular card movement) I used the drill bit method to ensure level precise cuts.
