How to repair a Tipp-Ex Pocket Mouse 10m

With all Tipp-Ex PM models, the front spool was too small to accommodate the used tape. As a result, the tape was knotted at the front next to the spool until winding was no longer possible. Then, during the correction process, the tape is only pulled out at the front, but no longer wound. The device then no longer serves its purpose.

The repair is very easy, even if it is a bit messy (Attention: Tipp-Ex is really hard to get off!).

First open the case carefully with a screwdriver, do not use too much force, otherwise the plastic or the pins that hold the case together inside will break.

To open the housing the red nose has to be opened or pulled off. Remove the top, which is the one with the hole for the screwdriver. The inner workings of the mouse will then appear underneath.

Carefully remove the rubber that is supposed to provide the smooth rolling up and down. Make sure that the rollers do not come off.

Now take the front, small and probably very full roller and unwind about 5cm. Now comes the point of no return: Now you cut the tape.

The so freed spool is completely freed from the plastic tape garbage (best to unroll it right away into the garbage can).

Then cut a 3mm wide piece of a strip of scotch tape by splitting it and use it to stick the Tipp-Ex tape back onto the reel. Roll up a few turns, then reassemble the mouse.

Before closing the cover, it is essential to check the belt guide and tighten the belt: To do this, hold the encoder roller and tighten the belt with the waste roller.

Now press the lid back on, if you have ruined plastic parts when cracking open, simply glue it shut. The repair will not be necessary again.

It can be corrected again - until the reserve in the encoder roll is actually empty.
