Maintenance
Introduction
This chapter contains general maintenance and cleaning instructions for
the NovaJet 800 series printers.
Scheduled Maintenance
Scheduled maintenance consists of a list of checks that are planned to
be performed on a regular basis or when conditions warrant it.
Scheduled maintenance can be thought of as preventive maintenance
since its purpose is to prolong the life of the printer. It is not intended to
repair or isolate an existing problem, though it can sometimes be helpful
in detecting a condition due to a weakened component that has not yet
completely failed.
Below is a list of scheduled maintenance checks and their recom-
mended periodicity.
