Path is obstructed
Foreign debris is obstructing the check path:
• Loose debris – power the MICR Reader off and try to push out any loose debris on the check
path. Grab the cleaning card and force it through the check path (this is a manual process, the
motor will not turn on). Try this procedure several times until the debris comes out. Power
the MICR Reader on again.
• Wedged debris - the debris is wedged in and cannot be removed with the procedure described
above.
Is the foreign debris removable?
◊ if yes, remove and continue to step 02.
◊ If no, continue to step 18.

Motor sensor is blocked
The Motor sensor may be blocked by dust build-up or foreign debris (see Figure C-1). Use
forced air to clean the sensor.
Power off the MICR Reader and then Power on again, observe the LED indicator:
◊ If the LED indicator blinks red, continue to step 18.
◊ Any other LED indicator status, continue to step 00.
12 EMF noise/interference
When idle, if EMF detect is set to YES (see HW Command, Section 4), the MICR Reader
monitors the signal coming from the MICR head. If any signal (noise/interference) with
amplitude large enough to affect check reading is detected, the LED indicator blinks red/green.
Possible sources of EMF are monitors, AC adapters, or magnetic devices. Set EMF to NO, or
move the MICR Reader at least 6 inches away from the source of noise/interference.
Determine if the condition described above is true:
◊ If yes, rectify and continue to step 00.
◊ If no, continue to step 13.
