Swab Printheads

Introduction
To ensure optimal print quality, it is important to periodically clean the
printheads with a swab to remove any excess ink or any debris that was
not removed by Printhead Maintenance.
Purpose
Important Caution: To maintain print quality it is very important to swab
the printheads at least once a week, or more frequently, if required. Failure
to do this may result in permanent printhead damage.
When to do
At the end of each week, clean the printhead nozzles using the swabbing
procedure. This procedure may also be used when regular printhead
maintenance fails to fix blocked or misfiring nozzles or to remove debris
from the printhead.
NOTE
If UV ink has fully cured on a printhead it must be replaced. Contact your
Océ service representative.
Before you begin
Print a Nozzle Check to determine if any nozzles are not firing properly.
This will help to determine whether some or all of the printheads must be
swabbed. You can also do a visual inspection of the nozzles (use a
flashlight if the ambient room light is not adequate).
A small bottle (125ml) is supplied with the printer accessory kit. Label this
bottle as "Flush" and use it only to hold flush for use during the swab
procedure. To prevent contamination of the flush in the bottle, never re-dip
a used swab in the flush.
