Swabbing Printheads

Perform at the beginning of each day, or as required.
Items Required:

•

Foam Tipped Swabs (0505-0285)

•

CGS-80 Solvent (3000-0057)

•

Butyl Gloves (30101017603010101760)

Procedure:

Gather 6 unused foam tipped swabs. One swab for each color is recommended.

Use protective butyl gloves in case of contact with ink or solvent.

Pour CGS-80 solvent into a solvent cup (part #3010100910). This cup has four

compartments, one for each color (light cyan and cyan, light magenta and

magenta share the same compartment). The solvent in each compartment is good

for multiple cleanings.

Use the Access Carriage command from the control panel to automatically move

the carriage to the blotting station.

Open the gantry doors and lower the blotting station in order to access the

printheads.

Use a flashlight and inspect the nozzle plates of each printhead for any foreign

debris such as hair, lint or dirt before swabbing.

Saturate a clean swab with solvent.

Start with a single color. Gently move the swab along the length of the nozzle

plate. Move the swap laterally during swabbing to insure no debris from any one

Warning:

Never use Isopropyl alcohol to clean the printheads.

Warning:

Each swab has a seam that may scratch the nozzle plate. For
cleaning use the long semi-curved smooth sides of the swab.
