WARNING: HAZARDOUS INKS AND SOLVENTS. SAFETY GLASSES
AND SOLVENT-RESISTANT PROTECTIVE GLOVES MUST BE WORN
THROUGHOUT THE FOLLOWING PROCEDURE. IGNORING THIS
SAFETY WARNING COULD RESULT IN SEVERE EYE IRRITATION
AND TEMPORARY (REVERSIBLE) EYE DAMAGE, AND
NON-ALLERGIC CONTACT DERMATITIS.
WARNING: SOLVENT JET HAZARD. THE USE OF THE NOZZLE
FLUSH FUNCTION MUST NOT BE CONFUSED WITH THE NOZZLE
CLEAR FUNCTION. WHEN THE NOZZLE FLUSH SEQUENCE IS IN
OPERATION, THE PRINTHEAD MUST BE DIRECTED DOWN INTO A
SUITABLE RECEPTACLE IN ORDER TO CONTAIN THE SOLVENT.
The Nozzle Clear sequence uses the pump to create a vacuum in the nozzle
while you apply solvent to the nozzle (see Figure 6-16). The vacuum pulls
the solvent into the nozzle. The reversed solvent flow can clear a blockage
behind the nozzle. The Nozzle Clear sequence takes approximately 20
seconds.
The printer can perform a series of eight Nozzle Clear sequences
automatically. You can stop the Nozzle Clear before all eight sequences are
performed, or repeat the sequence to make sure that the nozzle is clean.
To clear the nozzle
1. Make sure that the printer status is “IDLE”.
2. Remove the printhead cover tube.
3. At the Print Monitor page, press the Menu key.
4. Select Nozzle Clear to display the Nozzle Clear page:

NOTE: The Nozzle Clear option is not available unless the jet is
stopped. Press the red [stop] key to stop the jet.
