Start sentinel adjustment 
The Track # boxes show the current start sentinel values 
and the format defined for the track. This allows for 
adjusting the start sentinel position to a custom location. 
Refer to the 
Start Sentinel Position adjustment procedure 
on page 
5-35 for further information. 
Calibrate MS head  This option automatically calibrates the printer for 
variations in mechanical components. Refer to the 
Start 
Sentinel Position adjustment procedure on page 
5-35 for 
further information. 
Trailing offset  This setting determines how far the card travels to ensure 
that trailing clock pulses are encoded for the entire length 
of the card.  
Retries  This setting indicates how many times the card is re-read in 
the event of a read-back error. Note that during a retry, 
the card is read in both the forward and reverse direction 
regardless of the mode set in read back mode. 
Read back mode  This setting determines the direction the card is read 
during the initial verification (not including retries).  
Forward: This setting provides more reliable data read-
back but decreases throughput because the card needs 
to return to the front of the printer before being read. This 
setting should be used only if there are frequent read back 
errors. 
Reverse: (default setting) In reverse mode, the card is read 
on its return from the back of the printer. This mode is 
faster, but it may result in more frequent read-back errors.
