How to Clean a MICR/Check Reader

Check readers use a magnetic head to read and validate the coded account number and bank routing number on a check. Check readers accumulate dirt and contaminants during normal operation which leads to read errors.

By not cleaning, you risk increased:

  • Missed sales or checks that cannot be authorized
  • Labor costs to reconcile poor images
  • Read errors
  • Checks slipping and jamming
