card.
Always remove the card before you remove the controller

Inserting a card
You can insert an identity card into slot A only.
1. If you use an identity card, turn off the printer. If you use a
font card, set the printer off line. (If the FEED light is on,
press FEED to print out any data before you insert the card.)
2. Hold the card so that the arrow is on top and points toward
the slot.
3. Gently slide the card into the slot until it is flush with the
front of the printer.
