Island Card Reader
How to Clean the Magnetic Strip Reader
If your system reads magnetic cards in one or more island card readers or
consoles, then you need to clean the magnetic strip reader units periodically. A
magnetic strip reader that needs cleaning has a harder time reading cards,
requiring several passes to read some cards.
How often magnetic strip readers need to be cleaned depends on how often they
are used and also the type of environment. Generally, island card readers need to
be cleaned about once a month, but island card readers with many diesel fuel
transactions may need to be cleaned weekly.
A special cleaning card is used to clean magnetic strip card reader units.
Magnetic strip cleaning cards are available from Gasboy (part number C08757).
These cards are individually packed in foil wrappers containing an alcohol-
based cleaning solution. After removing the card from the wrapper, pass it
several times in the usual direction through the strip reader, then discard it.
How to Clean the Optical Card Reader
Optical card readers should be cleaned with a clean handkerchief wrapped
around an optical card. Dampening the handkerchief with rubbing alcohol or
glass cleaner may help. Hold the card by the end and insert it endwise in the
reader, then move it gently from side to side. Be careful not to damage the card
guides at the edges of the reader.
Optical card readers should be cleaned about every three months, or more
frequently if you observe an increase in the number of reader errors.
