Maintenance Guidelines
Introduction
The printer operator is responsible for the regular maintenance of the printer. This section
provides detailed information about what is required for proper printer maintenance.
While Océ furnishes guidelines for periodic maintenance, the optimum maintenance schedule
evolves from careful observation of your printer over a period of use. For example, some
specified maintenance may be required each time you use a particular media. The type of print
job can also determine the maintenance schedule. If the printer produces a high volume of solid
fill prints, it requires more tending than if it prints low-coverage images. Océ requires that the
operator follows minimum cleaning and replacement guidelines as described in this User
Manual.
A few minutes spent cleaning helps to ensure the highest quality prints. Each production
situation is different and involves different types of print jobs, environmental conditions, duty
cycles, and volume of work. While we provide guidelines for periodic maintenance, the optimum
maintenance schedule depends on operator observation of the printer over a period of use.
IMPORTANT
Keeping the printer clean, especially all parts associated with the printheads, assures that your
printer performs at its optimum and makes it easier to diagnose a problem, such as a leak. Daily
cleaning of all mechanical parts on the printer is highly recommended.
Who Should Do Maintenance?
If your site has a technician in charge of machine maintenance, that person is the optimal
candidate. While routine maintenance may be performed by any trained operator, the best
maintenance results from familiarity with the printer's internal operation and history.
Operator Maintenance Schedule
Your printer requires regular maintenance. Periodic cleaning should be scheduled for some
components during the week. A few minutes spent cleaning ensures the highest quality prints.
Several areas require maintenance to ensure the highest print quality, and the printer design
gives you easy access to all these areas. Diligent application of the maintenance schedule
ensures optimum performance from your printer.
NOTE
Do not bump the carriage or gantry as this can cause dropouts in the printhead nozzles. A hard
bump can break the meniscus vacuum in the ink lines and thus allow air into the lines, which
blocks the nozzle until a purge is performed. Also some procedures, such as Printhead
Maintenance, require that you slide open the door to access the maintenance station. Do not
bang the door hard when you close it after maintenance.
The following table provides our recommended maintenance schedule. This is a minimum
requirement and some procedures may need to be done with greater frequency. Each of the
procedures is explained in detail in this section in the order of frequency required as presented in
this table.
