HP-67 Card Reader became very touchy

Now I have the opposite condition. Most of the time I get an error message and a card is read correctly once in a while. It seems that something is no longer adjusted properly.
The wheels have been changed a couple of times, and a card running through seems to have no problem.
Is this a common issue? Is there someone that could fix my reader (for a fee)?

Thanks for your help,

The power supply capacitor may be failing.

Prior to reading this, I added an answer to this and another issue as a PM
