For your safety when running this test, make
sure personal articles such as ties, necklaces,
or bracelets do not get caught in the moving
print head.
MICR Check Reading Failure
Magnetic interference from a nearby video
display, transformer, power supply, or other
electrical device can cause MICR check
reading failures. If you experience this
problem, try moving any suspected electrical
devices away from the printer as far as
practical.
1
Open the cover on the printer.
2
Ensure the following conditions are met:
¹
The printer is attached to the POS
terminal.
¹
The power is ON at the POS terminal.
¹
There is no document inserted in the
document insert station.
¹
The paper is installed correctly in the
customer receipt print station. For
installation instructions, see the
reference documentation for your
system.
3
With the check face down and against the
right side frame, push the check inward until
it stops. The green Ready LED comes ON.
4
Press and hold the green Ready button for
three seconds to initiate the MICR test.
Note: If you continue to hold the Ready
button, the test repeats every three seconds.
The check is fed into the printer until it gets
to the top. The checkfeed is reversed and
the MICR characters are read while feeding
out the front. The MICR characters read are
then printed at the customer receipt station.
When the test detects failures on the first
read operation, it automatically feeds and
reads the check a second time. After the
check is read a second time, the characters
that were read are printed, regardless of any
read errors.
5
Compare the characters at the bottom of the
check with those that are printed. The
numeric characters should be the same.
See Table 2-1 on page 2-18 for special
characters.
¹
The test does not detect the presence of
a check (Green Ready LED does not
come ON).
¹
No characters are printed after the check
is read.
¹
The printed characters are different than
those printed on the check.
¹
Two passes of the check are required to
read the characters.
¹
The checks jam.
6
The stand-alone MICR test is complete.
