4 Printer Maintenance
4.1 Print Head Cleaning Instructions
The print head and platen roller may need cleaning after printing a number of rolls of paper,
when new supplies are loaded, or when voids in the printout are apparent.
Do not use sharp objects to clean the print head. This may damage the printer and
require service or repair
 Open the paper door by pressing the Paper Door Release Button as shown in Figure 6 . The
paper supply door will pop up.
 Remove the paper roll.
 Moisten a cotton swab with isopropyl alcohol and clean the print head.
 Clean the platen roller with a dry cloth or small brush.
Note: Another cotton swab moistened with isopropyl alcohol may be used to clean the platen. Turn
the platen roller with your finger and run the cotton swab or dry cloth across it. Ensure that the platen
roller is clean all the way around.
 Moisten another cotton swab with isopropyl alcohol. Rub the swab across the black mark
sensor to remove build-up
 Moisten another cotton swab and rub the swab across the tear bar to remove build-up
Note: Dust build-up may occur depending on the environment and the quality of the paper supply
used. If this occurs, use a can of compressed air to blow dust and paper debris out of the printer.
