• After replacing the MSR, test a card to be sure it swipes
correctly, and run diagnostics using the 7452 Diagnostics
Diskette (497-0406703).
• Check to see that the MSR is aligned properly with the guide by
swiping a card backward and forward. The card should swipe
smoothly, and you should not feel a bump when the card passes
through the guide. Non-smooth swiping is usually caused by
improper harness routing and failure to seat the MSR securely
in the base of the keyboard cabinet.
