What to Do
Line up the form or check against the Check Guide
(wall) and slide it toward the back of the printer
until it contacts the Form Stop and can't go any
further. Extra long forms may need to be inserted
from the side to disengage the Form Stop. See
"Printing on Forms or Checks" or "Validating and
Verifying Checks" in this document.
Open the front cover and check for any paper jams
or obvious obstruction in the slip station. Clear the
obstruction or jammed paper.
See "Clearing Paper Jams" in this document.
Make sure the check is inserted properly with the
MICR characters down. See "Validating and
Verifying Checks" in the Owner's Guide.
Make sure that the check is not fraudulent. On
fraudulent checks, the characters the printer reads
may be different from those that are visible on the
check face.
Devices, such as CRT monitors, security devices or
large metal surfaces that are near the printer can
affect the printer's magnetic field, causing
intermittent reading errors when the MICR check
reader is in operation. Move the printer away
from such items or areas.
Replace cassette with a cassette approved for the
check flip option.
