Clean the following components after 8 rolls of stock.
In each case use a cotton bud dampened with alcohol. Do not soak the cotton bud
excessively.
ALWAYS SWITCH OFF THE MAINS POWER BEFORE CLEANING!
(a) Thermal Print Head
Thermal paper stock and ribbon will release debris on the print head and degrade
printing quality. Clean the print head with methanol or isopropyl alcohol with a cotton
bud. Do not touch the heater element with your fingers.
