5 A Cleaning The Print Head
Dirt on the print head or ribbon, or glue residue from the label stock may result in inadequate print quality. The printer cover
must therefore always be closed during printing. Keeping dirt and dust away from the paper or labels ensures a good print
quality and a longer lifespan of the print head.
Cleaning Steps
Here is how you clean the print head.
1. Switch off the printer.
2. Open the printer cover.
3. Release the printing mechanism and lift it.
4. Remove the ribbon.
5. To remove any label residue or other dirt from the print head (see blue
arrow), please use a soft lint-free cloth dipped in isopropyl alcohol.
Note: The print head should be cleaned once a week. Please make sure that there
are no metal fragments or other hard particles on the soft cloth used to clean the print head.
5 B Adjusting The Print Head Pressure
When printing on special media (with varying material thickness), the print quality may suffer. You will then need to adjust
the print head pressure.
Adjustment Steps
1. Open the printer cover.
2. Remove the ribbon.
3. Use a screw driver and slowly turn the adjustment screws for the print head to increase or reduce the print head
pressure.
