3. In the Operator / Maintenance Menu, select Raise Carriage to move the carriage to
the Purge Position.
4. Starting with the 4 Black Heads, disconnect the tube connections between the Ink
Reservoirs and the tube supplying the Print Head. Plug the fitting to the Ink
Reservoir with a Male Luer Plug immediately after disconnecting each connection.
5. Connect the syringe to the head supply tube and syringe the head with approximately
1/8 of a full syringe of solvent. Ensure the carriage is still in the Purge Position.
Figure 30 Syringing the Heads
Tip: If the syringe contains any air, then point it upwards during use to expel the air – this
will prevent any solvent from leaking out over the carriage when disconnecting the
syringe.
6. Repeat for all colors.
7. Syringe all of the Print Heads for a second time. If a blocked nozzle or poor
directionality is suspected observe the “curtain” of solvent exiting the nozzles. If the
"curtain" has gaps or sprays off to the side, use more solvent to clear the nozzle.
8. Immediately after syringing each Print Head, plug the Head Supply Tube with a
Female Luer Plug. Wait for at least 1 hour (overnight is better) for the solvent to
suitably clean the Print Head.
Note:
In this state the printer can be powered off for a number of days. If the printer
is left in this state for more than a few hours, squirt some additional CGS 80
onto the Foam Capping Pads to prevent them from drying out.
