Using The Micr Reader (Option); Reading Micr Characters On Personal Checks - Epson TM-U950 Operator's Manual

Using the MICR Reader (Option)

If your printer has the factory installed optional Magnetic Ink
Character Recognition (MICR) reader that enables the printer to
read and process MICR characters on personal checks, read this
section.
CAUTION:
Be sure both paper rolls are installed before you use the MICR
function. Even when you are not using roll paper, this prevents
paper jams.

Reading MICR characters on personal checks

To use the MICR function with personal checks, follow the steps
below:
CAUTIONS:
Do not insert checks with staples in them. This may cause
paper jams, MICR reading errors, and damage to the MICR
head.
Be sure that the checks are flat, without curls, folds, or
wrinkles.
1. Wait until the computer sends the FS a 0 command to the
printer, causing it to enter the MICR mode. The SLIP light
blinks.
