Swab Printheads
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 nozzle plates 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 bottom of 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.
