2. CLEANING THE PRINTER
For best printing results, use the following procedure to clean the print head and rollers with alcohol.
Also note that tape adhesive tends to accumulate on the sides of the tape outlet after long use of the
QG-100. When this happens, use an alcohol-moistened cotton swab to clean off the adhesive.
1 Open the printer's cover.
2 Use a thin cotton swab (the kind designed for infants)
moistened with alcohol to lightly wipe the printer head
as shown in the illustration.
3 Thoroughly wipe off the rubber rollers with the cotton
swab.
Important!
· The print head and other nearby metal parts become quite hot after the printer is used for a long time.
Make sure you allow these components to cool sufficiently before cleaning.
