How To Perform Printhead Maintenance
Introduction
The Maintenance Station is located below the carriage. Printhead Maintenance takes place while
the carriage is parked. The station is covered by a sliding drawer that has an open grid in the
center that allows any waste ink to drip down through the station and into the waste tray. When
you perform printhead maintenance, any excess ink and associated debris are removed from the
nozzles with the result that ink drops can jet properly when the nozzles are clear.
Ink fill is disabled when the maintenance station drawer is open. No more than 4 purges can take
place (minimum of 10 seconds between purges) without closing the cover plate and allowing the
reservoirs to refill. Multiple purges are not required.
IMPORTANT
The nozzle plate on the printhead has a non-wetting coating - contact with this surface may
affect the performance of the printhead. Do not wipe the nozzle plate with anything other than
the suction-head (or the supplied swabs when following the swab procedure) as this can
damage the nozzles and impair performance.
Purpose
To clean the nozzles of the printheads and thus ensure better image quality and avoid banding.
NOTE
The complete Printhead Maintenance procedure is documented in a video production that
illustrates all of the steps involved and also explains why it is important to perform regular
maintenance. Do NOT start suction on the printheads immediately after a purge as indicated in
the video and previous versions of this user guide. Wait for the ink drips to slow down before
you apply the suction. The video can be viewed from the main Customer Support page and is
also available to download: http://dgs.oce.com/.
When to do
Printhead Maintenance occurs at the start of the day (after the printer has warmed up) or when
necessary (misfiring nozzles, banding in image, etc).
IMPORTANT
More maintenance is required in dusty environments, or when there are fibers protruding from
the media, or when printing on reflective media such as glass or metal (more reflected UV light
hits the printheads). When printing on reflective media it is advised to monitor the nozzle check
and printhead nozzle plates and to perform additional printhead maintenance, if required, to
prevent ink from partially curing/gelling on the printhead nozzle plates.
Before you begin
Make sure the carriage is in the parked position. The carriage and gantry automatically return to
this position after an image is printed. Do not move the carriage or gantry from this position as
this will disable the ink pumps and thus prevent the performance of an ink purge, which is
necessary for printhead maintenance.
CAUTION
It is not necessary to turn off the UV lamps as they are shuttered. However, they will be hot if
they were recently on, so avoid touching them.
