Be sure that the printer is turned off. Open the roll paper cover and
clean the thermal element (the green part) of the thermal print head
with a cotton swab moistened with an alcohol solvent (ethanol,
methanol, or IPA).
Clean the thermal print head periodically (generally every 3 months)
to maintain receipt print quality.
See illustration I.
MICR Reading/Image Scanning/Printing
(Factory installed options)
With the scanning function, when a check is inserted into the printer,
the check image is digitized and stored, which saves check processing
time and cost. EPSON recommends the following sequence for single-
pass processing. The single pass eliminates the need to turn the check
paper over.
1. MICR reading
2. Pre-scanning
3. Endorsement printing (printing on back)
4. Printing on front
5. VOID printing
6. Scanning
Notes on Using the Slip Image Scanner
❏ Be sure to include the pre-scanning step because it can minimize
as much as possible problems of decreasing image data quality
caused by environmental temperature, wear of scanner parts,
great variation in color shading of the background of a check, and
input voltage fluctuation.
❏ The quality of image scanning on the front of a check may be
reduced by a large variation in density of an ink ribbon cassette.
❏ Be sure to consider these other conditions that may reduce image
quality:
• Extremely low density of handwriting on the front of a check.
• Extremely high density of the background of a check.
• An extremely large variation in the density and color tone of
the background of a check.
• Many folds or wrinkles in a check.
