THE FOIL
Keep the color cartridge in its sleeve and store it in a clean and protected
environment when it is not installed in the GERBER EDGE. Store the
cartridge at 40 to 60 percent relative humidity in a temperature range of
40° - 90°F (4° - 32°C). Do not store the color cartridge in direct
sunlight.
The color cartridge can become contaminated in two ways: in storage,
where dust is attracted to it because of static charges; and during use. If
the color cartridge is out of the GERBER EDGE, use a compressed air,
ultra-filtered, non-residue dust remover, such as Chemtronics
Ultrajet 2000 or equivalent, to quickly spray both sides of the foil in
the color cartridge before loading the color cartridge in the GERBER
EDGE. Do not soak the foil -- just spray it enough to blow the dust off
the foil. If the color cartridge is in the GERBER EDGE, use the foil
slew key to advance the foil several inches so that the contamination
buildup is rolled beyond the printhead and into the color cartridge.
THE PRINTHEAD AND FOIL SQUEEGEE
There are two times to clean the printhead: normal cleaning, and
removing contamination buildup.
Normal cleaning refers to cleaning the printhead before each job. If a
job is longer than 10 feet, clean the printhead before loading each color
cartridge. Use the pen printhead cleaner or a pad moistened with 91%
isopropyl alcohol to gently rub the entire length and width of the
printhead as shown. Dry the printhead with a clean, lint-free cloth.
