Maintenance Guide
5.1
Maintenance Overview
To ensure reliable operation and high print quality while using the product, the regular
inspection and maintenance steps are required to be performed. These include
mechanical subsystems checks, occasional cleanings, consumables changing and print
head cleaning.
Cleaning
The most essential maintenance operation is automatic – cleaning the print head and
preventing it from dehydration. The print engine performs various maintenance
operations before and after print jobs and in the background. Normally manual print
head cleaning is not required.
Regular checks
At regular intervals (say at the beginning of a shift or day) inspect that the maintenance
station is in cap position, the cutter is not obstructed, the paper path is clean (there are
no paper clippings present), sensors are not covered. Check that wires are not loose,
there is no ink leaking.
If the operator detects print quality problems, check the troubleshooting part for steps
to perform in order to solve the issues.
Consumable change
The main consumables in the printer are the ink and the print head. The most frequent
user intervention during the life time of the printer is the ink cartridge and print head
change.
When the printer is running out of a particular ink, the Liberty controller will display a
message on the screen specifying which tank is out of ink. Remove the empty tank and
insert a new one and the printer will operate again as before.
NOTE:
The printer is working only with all cartridges installed!
If the operator need to change a print head due to unrecoverable printing defects,
open the Maintenance menu and select Replace Printhead command. This starts a
wizard that will guide you through the print head change procedure. Follow the steps
and wait until the wizard finishes its operation.

Standard Maintenance
General and periodic maintenance procedures are needed to keep the Print Engine in
good condition. In anticipation of industrial applications, an extensive list of service parts
are available for the printer. Please contact you Reseller for futher details.
High volume usage and specific use cases/configurations may require more frequent
maintenance.
