Locate the Clear Nozzle option. Type in the number of Clear Nozzle sequences you wish to run. DO NOT
press key to start the nozzle clear sequence yet - the following procedure must be carried out first:
NOTE: A minimum of three Clear Nozzle sequences is recommended in an attempt to clear a nozzle
blockage. This can be performed as a continuous routine by entering “3” in the Clear Nozzle option and
pressing [enter].
While wearing disposable gloves:
1. Remove the print head cover.
2. Wash the print head as described in “Cleaning the Printhead” ensuring the nozzle area is clean.
3. Invert the print head, with some absorbent material wrapped around it where it connects to the conduit,
and hold it in a vertical position.
4. Activate the Clear Nozzle routine by pressing the [enter] key.
5. The status line will indicate that the printer is clearing the nozzle.
6. Apply small amounts of solvent to the inverted nozzle face as illustrated below. It should be observed
that when a small drip of solvent is applied to the nozzle face, it will be drawn in through the nozzle
orifice and back into the assembly.
7. Apply drops of solvent repeatedly until no more solvent is drawn in.
8. The routine of three Clear Nozzle sequences should be carried out a maximum of 10 times, with an
attempt to start the jet at the end of each routine. If the nozzle is still blocked after the 10 routines have
been completed, the print head should be replaced.
