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 Display Graphics Systems 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
Display Graphics Systems 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.
