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.

If the EC:19 does not clear or the FEC display still does 
not reflect a card insertion, try substituting another card 
reader. 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 reader was bad, and the new one 
should be used to replace it. Try several cards in the 
new reader to ensure correct operation.

If substituting with a new known good reader and a 
new known good harness does not clear the EC:19 and 
allow card insertions to be displayed by the FEC, the 
Front-End Control will probably need to be replaced.

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:

• 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.

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 
may need to be replaced

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.

EC:26 – Card Write Error

EC:26 errors can occur in cases where neither the 
reader and the card which caused the EC:26 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.

Therefore, it is necessary to try numerous cards 
numerous times before deciding whether an individual 
card or reader is in need of replacing. 

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.

If a given card repeatedly gives EC:26’s, the card will  
need to be replaced.

If a given reader repeatedly gives EC:26’s with a 
variety of cards, the reader will need to be replaced.

Other Errors

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.
