I recently rebuilt my Card Reader. The card runs smoothly, but I consistently get Card Err or Malfunction or Checksum Error.
Some threads point to the 2 contacts. I swapped and checked to make sure they are flat. I applied contact cleaner as well.
I tried a different calculator, but that didn't work.
Suggestions?
Hi Adam,
If you get inconsistent results, then I'd say there is hope. And I presume you had never seen such errors before the rebuild /
My guess is that you need to spend more time adjusting the roller pressure.
Is the motor struggling ?
Cheers,
John
I swapped the rebuilt drive assy with another card reader I had.
This assembly works great. So, I presume from browsing older posts, the cause of these errors/malfunctions could be the capacitor adjacent to the sense amplifier chip. I will try this next after I rebuild another drive unit.
