Routine Cleaning
The parts of each print station, especially those that come in direct contact with
the ribbon, will accumulate residue. To maintain clear and crisp printing, these
parts should be cleaned frequently. The printheads in particular require regular
cleaning. QuickLabel Systems recommend that these surfaces be cleaned when
changing a roll of media or ribbon.
The illustration below indicates the locations for regular cleaning. It is recom-
mended that these surfaces be cleaned with a soft cloth or lint-free wipe soaked
with Isopropyl Alcohol. Harsh chemicals and solvents should be avoided as dam-
age to the printhead could occur.
1 Print Line
2 Platen Roller
3 Peel Edge
4 Ribbon Guide Rollers
5 Drive Roller
6 Pressure Roller
Caution
Always power off and unplug the printer before cleaning the printheads.
Never use a hard object of any sort to clean the printheads. Damage will
result if the edge of any hard object is used to scrape away accumulated
printing residue from the printhead.
