Cleaning the Thermal Print Head
CAUTION:
After printing, the thermal print head can be very hot. Be careful not to touch it.
Also let it cool before you clean it. Do not damage the thermal print head by
touching it with your fingers or any hard object.
To keep good print quality, remove paper dust from the thermal print head as
follows.
See illustration H.
Be sure that the printer is turned off. Open the roll paper cover and clean the
thermal element (the part indicated by the arrow in the illustration) of the thermal
print head with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
Clean the thermal print head periodically (generally every 3 months) to maintain
receipt print quality.
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.
• Exposure of the image scanning part of the printer to strong sunlight.
• Any foreign object, such as sand, entering the printer and scratching the
glass surface of the scanner.
