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 MICRSafe and then power on again; then observe the LED indicator:
◊ If the LED indicator blinks red, continue to step 18.
◊ Any other LED indicator status, continue to step 00.
11
EMF NOISE/INTERFERENCE
When idle, if EMF detect is set to YES (see HW Command, Section 4), the MICRSafe monitors
the signal coming from the MICR head. If any signal (noise/interference) with an amplitude
large enough to affect check reading is detected, the LED indicator blinks red/green. Possible
sources of EMF are monitors, DC adapters, or magnetic devices. Set EMF to NO or move the
MICRSafe 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.
12
DATA SENSOR IS BLOCKED
The data sensor may be blocked (see Figure C-1). Try one or both of the following procedures:
• Forced air - use forced air to clean the sensor.
• Cleaning card - power off the MICRSafe and try to push out any loose debris in the check
path. Grab a 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 off the MICRSafe, then power on again and observe the LED indicator:
◊ If the LED indicator blinks red/green, continue to step 18.
◊ Any other LED indicator status, continue to step 00.
