Print Head Handling
Warning
Print heads can be damaged easily, and are subject to premature failure if not cleaned
on a regular basis. Please follow the procedures carefully to help ensure print head
life and print quality.
Thermal print heads are very sensitive and must be handled with care to help ensure
longer print head life. Because print heads may be damaged through a number of
ways, AVERY DENNISON has developed the following procedures;
Handling
Static discharge is very detrimental to thermal print heads. To avoid contacting print
heads with a static charge, follow these simple procedures:
- All print heads should be kept in original anti-static bags until they are
installed in the printer.
- The 656 / 636 printer is supplied with an anti-static wrist strap. Locate the
strap - it must be worn at all times when handling the print heads.
- Do not touch any terminals extending from the print head or the print line.
- Anti-static gloves are provided with your printer upon installation and
extras may be ordered from AVERY DENNISON. These gloves must
be worn at all times when handling the print head. If an anti-static glove
is not available, make absolutely certain to thoroughly wash and dry your
hands before handling the print head. Oils from your hands can
contaminate the print line and quickly destroy the printing elements.
