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 needed. Failure to do this may result in plugged printhead
nozzles.
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.
Required tools
Foam Tipped Swabs (3010105434 Swab Foam Flex Tip)
Flush (3010106646 Flush UV 1Liter) or Isopropyl alcohol (99% pure)
Bottle-HDPE 125ml for flush (3010105433)
Nitrile Gloves
Safety Glasses with side guards
IMPORTANT
Never "scrub" the printhead with a swab as this will drag debris into other nozzles.
Always slowly move the swab across the printhead with the swab at a slight angle and not
perpendicular to the printhead.
Do not allow swabs to be contaminated with any dust or dirt prior to use.
Note that the swab has a seam that can damage the printhead nozzles; use only the semi-curved
foam sides of the swab.
CAUTION
Use appropriate safety equipment — nitrile gloves, an apron, and safety glasses with side
shields to protect your eyes.
