Avery 676 user manual Print Head Handling, Clean Platen Roller

Clean Platen Roller

You may determine if the printhead has been adjusted properly by performing a test pattern as documented elsewhere in this manual. A properly adjusted print head will produce an even grid of chevrons when the test pattern is performed. Before making any judgments as to the quality of the printhead, it is absolutely necessary to ensure that the platen roller and the printhead are clean of all debris. Clean the platen roller located immediately beneath the print head with a clean cloth and a small amount of alcohol. Be careful not to damage the platen roller while cleaning. If the roller is worn, replace the roller.

Supplies:

-Always use clean supplies when cleaning the sensor and light bar.

-Never use anything abrasive to the sensor and light bar.

-NEVER use an alcohol-based solution when cleaning the sensor or light bar.

-Dry air or a cotton swab are the AVERY DENNISON recommended items to use when cleaning the sensor and light bar.

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 placed in the machine.

-The 676 LKP 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 machine 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.
