1.0 Daily Cleaning of the Printhead
To ensure that the printhead operates reliably and to maintain print
quality, it is necessary to clean ink and contaminants from the jet
array daily, using the following procedures:
• Purging
• Jet Testing
• Wiping (only if necessary)
when several attempts at purging are unsuccessful
or in the down jetting position, after each purge
Perform these procedures at least once daily or:
• At the start of each shift
• After each cold startup
• If the coder has been idle for more than 4 hours
• If the jets are not printing properly
NOTE: Use only Markem-Imaje Printhead Wipes (PN 0712075) to
remove ink from the jet array surface. These Printhead Wipes were
specially designed and tested for use with the coder, and prevent lint
particles from getting into the jet array surface. Use of non-Markem-
Imaje Printhead Wipes will cause jet array blockage and will void the
printhead warranty.
NOTE: DO NOT MOVE A HOT PRINTHEAD. Movement will cause
ink to flow into the low vacuum line, and the printhead may require
servicing. It takes approximately 40 minutes for the printhead to
adequately cool down and three to four hours for the coder to fully
cool down and the “Shut down” message to appear.
