If the EC:19 does not clear or the FEC display still does
not reflect a card insertion, try substituting the harness
from the FEC to the reader with a known good harness.
Wait about 20 seconds. Check the FEC display to see
if the EC:19 goes away, and that FEC does reflect the
card insertions. If both conditions are satisfied, the old
harness was bad, and the new one should be used to
replace it. Try several cards in the new reader to ensure
correct operation.

EC:20 – Error Reading Card
EC:20 errors can occur in cases where neither the
reader and the card which caused the EC:20 are faulty.
This can occur for the following reasons:
reader and the card which caused the EC:20 are faulty.
This can occur for the following reasons:
• The reader and card contacts are not making a good
connection due to dirty contacts.
• Intermittent poor connections.
• The user not inserting the card properly.
• The user not inserting the card properly.
Therefore, it is necessary to try numerous cards
numerous times before deciding whether an individual
card or reader is in need of replacing.

If EC:20’s are consistently received on an individual
card, but not on others, the card which gives the errors

If EC:20’s occur often with different cards, the card
reader’s contacts should be cleaned. If, after cleaning,
the problem persists when numerous cards have been
tried numerous times, the reader is not reading cards
properly and should be replaced.

If an EC:26 error occurs once on a given card, and does
not happen again in later transactions, the card and
reader are probably OK, and neither would need to be
replaced.

The following errors should only occur if a firmware
load has been attempted on the card reader. Under any
other condition, if an EC:2A, EC:2C, EC:2D, EC:2E,
EC:2F or EC:30 appears, the reader should be replaced.
