SPECIAL CONSIDERATIONS
1.
Cleaning Printwheels
Print Wheels used with carbon ribbons seldom need cleaning. Printwheels used
with cloth ribbons will require an occasional cleaning.
Remove the printwheel and clean with toluene or naphtha * and a soft brush or
wiper. DO NOT clean with water. Make sure to keep the reflective "code"
segments on the back or character side of the printwheel clean and shiny. Be
careful not to bend the "spokes".
2.
Cleaning the Platen and Paper Rollers
Platens and paper rollers are made of rubber. They require periodic cleaning
for a more positive friction paper drive. Periodically clean the platen, paper
bail rollers and pressure rollers with soft tissues or cloth wipers and a good
commerically available platen cleaner.
3.
Cleaning the Card Guide
Remove the ribbon cartridge, printwheel and platen. Remove the card guide
and clean it using soft tissue or a soft cloth and alcohol.
CAUTION: DO NOT use alcohol, water or platen cleaners ·to clean printwheels.
DO NOT use alcohol to clean platens or other rubber parts (it hardens the
surface).
DO NOT use platen cleaner to clean the card guide or other plastic parts
{it attacks the plastic).
*
Toluene and naphtha are available at most drug stores.
