Cleaning and
Maintenance
A Phaser 440 printer requires cleaning for optimum operation. Follow the
printer cleaning, lubricating and inspecting procedures in this chapter for the
best printer performance.
Cleaning
Generally, the following three steps are performed by the customer.
Each time the transfer roll is replaced:
1.
Wipe the line of heating elements on the thermal head with a lint-free
cloth dampened with 90% isopropyl alcohol. Also clean the thermal
head's transfer roll guide, located just above the row of thermal head
heating elements.
2.
Remove the front cover and wipe the surfaces of the three black
rubber feed rollers with an alcohol-dampened cloth.
3.
Clean the pick rollers. Customers can either do this with an
alcohol-dampened, lint-free cloth or use the pick-roller cleaning tray
provided in the cleaning kit.
Each time you service a printer:
1.
Wipe the line of heating elements on the thermal head with a lint-free
cloth dampened with 90% isopropyl alcohol to remove all traces of
dirt. Clean the transfer roll guide to remove all traces of dirt.
2.
Remove the front cover. Clean the six spring-loaded white plastic
rollers with an alcohol-dampened cloth.
■

■
Ensure that there are no nicks in the plastic ribs that might scratch a
print. If you do find nicks, sand them with 600-grit sandpaper.
