Check for abrasion or internal debris.
5.2.2 Regular Monthly Checks
Check the condition of the peel roller: Remove the roller, and then check if there is any
wear inside. Replace if necessary.
Check the condition of the ribbon guide rollers: Check whether the bearing is smooth.
Check the condition of the ribbon sensor roller. Inspect the roll coating for wear or
damage. If worn or damaged, replace the roller.
Make sure that all rollers are flat to the cassette or printer.
Check the magnet for any damage or non-alignment. This magnet is used for ribbon
detection and ribbon calibration.
Print a test image to check the print head quality and alignment.
Check condition of the print head carriage drive belt and its related components: pulleys,
bearing, retainers and shafts.
Check the air cylinder.
Make sure that the tension roller slide is free to move.
5.2.3 Maintaining the Print Head
Although specifically designed for the application, the print head is still subject to wear or
tear. For print heads, special consideration needs to be given to installation and periodic
preventive maintenance, which is very helpful to maximize the life of the print head.
The most likely cause of damage to the print head is abrasion: either from ingress of air
particles or from an abrasive substrate surface. As a result, print head life varies greatly
depending on the substrate materials and applications.
The thermal ribbon will protect the print head from abrasion. Using different width
ribbons and abrasive substrates may cause wear and unprotected parts of the print head.
Usually, abrasive substrates have pre-printed ink. In particular, some red inks may be more
abrasive than others.
