Daily Operation
Using the Magnetic Card Reader
The optional Magnetic Card Reader (MCR) is used by some applications to read information from credit cards,
drivers licenses, etc.
When the host system sends a request to the MtP300 to enable the Magnetic Card Reader, “Swipe Card Now”
will be displayed and the
MCR Indicator will flash to indicate that the card may now be passed through the
MCR slot, or “swiped”. Refer to
Figure 8 for the card orientation.

Figure 8 - Using The Magnetic Card Reader
If the card is read successfully, a short beep will sound, “Card Read Ok” will be displayed and the MCR
Indicator will stop flashing and remain on briefly to indicate success as the data is sent to the host system.
If the card is not read successfully, a longer error tone will sound, “Card Not Read” will be displayed and the
Error Indicator will also begin to flash. If the read operation is not cancelled by the host application within a
few seconds, the
Error Indicator will stop flashing and the printer will return to the “Swipe Card Now”
mode. At this time the card may be swiped again to attempt a successful read.
The length of time allowed before the timeout is specified by the host application program. Once a timeout
occurs, the
Error Indicator will turn on momentarily and “MCR Timeout” will be displayed.
