6-4. Magnetic Card Reader
The Magnetic Card Reader comes as standard with IT-3100M54E/M54E2/M55E/M55E2/M55U.
Only use cards that are compatible with the ISO standards. The procedure for reading cards is described
below.
1. Remove the cover as shown in the illustration.
2. Insert the card all the way into the reader as shown in the illustration,and steadily pass the card through
the reader in the direction of the arrow.
Precautions During Use
• Cards may not be able to be read if they are passed through the reader rapidly.
• A reading error may occur if the speed at which the card is passed through the reader changes suddenly.
• Do not allow magnets to come in close proximity to the magnetic card since this can prevent data on the
card from being read. In addition, do not stack magnetic cards on top of each other.
• Cards that have been excessively misshaped or bent may not be able to be read.
• Soiling of the magnetic strip may make it difficult to read the card. If a card has become soiled, wipe with
a clean and soft cloth.
• Regularly clean the magnetic card reader by passing a cleaning card through the reader to prevent
excessive friction with cards. When using in a location where there are low levels of dust, clean once a
week or about once every 500 passes through the card reader.
• Install the cover when not using the magnetic card reader. The drip-proof of the magnetic card reader is
not sufficient if the cover is not installed.
