Not accepting cards

MRX 35 DOES NOT ACCEPT CARDS.
ANSWER:
    The most common reason is that the actuator came out of place.  To fix this:
1-  Unplug the clock.
2-  Remove the top cover.
3-  Find the actuator behind button number 5.
4-  Push down on the actuator until it snaps back in place. ( see image below )
5-  Put cover back on and test.
