CP60 and CP60 Plus Service Manual  5-35 
Start Sentinel Position 
Perform this procedure any time you replace any component that can impact 
magnetic stripe registration. This includes all magnetic stripe components and 
any transport drive component related to moving the card past the magnetic 
stripe area. 
Mandatory Procedure: Even if you are manually setting the start sentinel 
positions, you must
 complete the Auto Calibration procedure first.  
Adjustment Procedure 
1.  Put a magnetic stripe card in the input hopper. 
2.  In Printer Diagnostics, click on the Magnetic Stripe menu and select 
Configuration. 
3.  Click Calibrate MS Head. The system will pick the card, pass the card 
through the magnetic stripe 10 times, and then eject the card.  
•  Note that this card will be blank (all zeros) and will not display data if 
read in a card reader. However, it can be developed with magnetic 
developing solution. 
•  The values (292, 290, and 292) will always be displayed after the 
calibration has been completed, regardless what changes were made 
during the auto calibration. In a sense, the system was calibrated to make 
these values correct. 
4.  If the customer requires a custom start sentinel position, alter the numeric 
entries for each track in the entry boxes. Since this is custom, you will have to 
refer to the customer’s procedure for this setting.
