application is recommended whenever possible.
Clean the MICR unit with the following steps.
1. Turn off the printer.
2. Open the roll paper cover, and turn on the printer with the CLEANING button pressed
down.
3. Press the CLEANING button once, and close the roll paper cover.
4. Insert a cleaning sheet. With ASF model printers, insert the cleaning sheet until the printer
starts pulling it in, as you pull the cleaning lever on the back of the printer.

Note:
Make sure to discard used cleaning sheets.
Hold the cleaning lever in the pulled position until the cleaning sheet is fed into the validation section. Not
doing so may cause a paper jam.
