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 Main-
tenance.
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.
