while testing our TI-59 (see other post) we have also tried out two PC-100C

They works quite well, the contacts to charge the battery in the battery compartment
were broken but those should be easy to replace

However, the printing from both is faint and non regular (see pictures)

Any idea on how to clean these ?

Rolls of TI thermal paper used to come with a head cleaning strip. It seemed like plain old card stock to me. It didn't have a glossy finish. You might try running a piece of card stock cut to the width of the TI paper through.
