If your Fargo DTC550 will not feed cards, take the following steps
Check to make sure that the card thickness gauge is set to the correct height
Make sure that the card weight is on top of the cards
Check to see if your cards have static build up and are sticking together
Clean the input roller thoroughly with an isopropyl alcohol card or wipe
Thank you for the instructions given to enable the printer to feed the cards. I have the same message of not feeding the cards, but in my case, the input roller is running in the reverse mode. Therefore, instead of taking the cards into the printer, the cards are ejected. Your assistance will be highly appreciated to help solve this issue. Thanks in advance.
Yaya KONE.
The input roller will turn backwards if the printer’s encoder setting is incorrect. You can read more about it here: http://badgepros.com/2011/idprinters/fargo/flipper-roller-turns-backwards-fargo-dtc5xx-printer/
