Fargo’s Clean Printer utility in the driver does not clean the mag encoder roller.
Keeping the encoder roller clean prevents card jams in the mag encoder and mag verification errors.
Take the following steps to manually clean the Mag Roller inside your DTC5XX Printer
The mag encoder is underneath the hopper area so you will need to rotate the flipper table to about a 45 degree angle first
Insert a Fargo 82133 Cleaning card into the flipper table and guide it into the mag encoder area. Use the right button to feed the card into the mag encoder. Hold the card while continuing to press the right button. This will put pressure on the roller and thoroughly clean the roller.
