Chapter 6 - MAINTENANCE
This chapter examines the cleaning and lubrication operations, and a number of mechanical adjustments necessary
for correct operation of the printer.
CLEANING
For correct functioning of the printer, it is suggested to clean parts of the machine periodically and after each
servicing.
Cleaning the case
Switch off the printer, disconnect it from the power outlet and clean the case with a damp cloth; do not use corrosive
substances such as solvents, alcohol, benzene or products with abrasive components.
Cleaning the paper paths
Clean all paper paths including the paper feed rollers of the insertion slot, taking care to remove any scraps of
ribbon or paper that may be deposited on parts and also any foreign objects.
LUBRICATION
Although operations for restoring the lubrication and grease levels are not normally required during the life-time of
the printer, it is nevertheless the responsibility of the field technician during every service intervention to check
them. When it is necessary to replace mechanical parts that were originally greased, proceed applying a same
level of grease.
The only points that may require restoration of lubrication (with oil) are:
• Print carriage sliding shaft
• Carriage felt.
