7.3.6 To Clear the Nozzle
WARNING: HAZARDOUS INKS AND SOLVENTS. SAFETY
GLASSES AND SOLVENT RESISTANT PROTECTIVE
GLOVES MUST BE WORN THROUGHOUT THE
FOLLOWING PROCEDURE. FAILURE TO COMPLY WITH
THIS SAFETY WARNING COULD RESULT IN IRRITATION
AND REVERSIBLE LOCAL DAMAGE TO THE EYES, AND
NON-ALLERGIC CONTACT DERMATITIS.
WARNING: SOLVENT JET HAZARD. THE USE OF THE
NOZZLE CLEAR FUNCTION MUST NOT BE CONFUSED
THE WITH NOZZLE FLUSH 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 Clear Nozzle sequence enables you to clear an obstruction or blockage
behind the nozzle by applying a vacuum to the nozzle. During the Clear
Nozzle sequence, unlike Nozzle Flush, solvent is drawn into the ink system
through the small orifice in the nozzle in order to clear the nozzle of any
obstructions, such as dried ink or any particles.
To clear the nozzle, do the following:
1. Ensure that the printer is in the “Jet Off” state. To verify this, check the
Status in the PRINT STATUS screen.
2. Remove the printhead cover tube.
3. At the CURRENT MESSAGE screen, press the [F4] function key to
display the SETUP menu.
4. Select Diagnostics Menu > Clear Nozzle. The printer displays a
“Clearing Nozzle : Please Wait” message on the Status Line to
indicate that the Clear Nozzle sequence is in progress. This message is
displayed for the duration of the Clear Nozzle sequence—
approximately 20 seconds.
