User Manual: Arizona 550 GT - Version 1.2, Revision B - 2012
Wipe the suction-head on a clean piece of new lint-free wipe before proceeding to the
7.
next printhead.
Note:
During maintenance, be careful not to touch the nozzle plates as this can damage the

printhead.

Slide the maintenance station drawer back to its closed position. The carriage will move
8.
back to its previous print-ready height.
Note:
Close the drawer gently to avoid disturbing the ink vacuum. A hard bump can break the
meniscus vacuum in the ink lines and thus allow air into the lines, which blocks the
nozzle until a purge is performed
Print a Nozzle Check to evaluate print quality.
9.
Note:
If the Nozzle Check print shows that a printhead still has a few nozzles out you can slide
the suction-head over that printhead again. Then print another Nozzle Check and if
there are still nozzles out, you can perform printhead maintenance on the printhead of
the same color only (See Maintenance for Select Printheads below).
How to Print a Nozzle Check
The Nozzle Check print fires each nozzle individually in a manner that allows clogged
nozzles to be easily identified by a visual inspection of this special print. The Nozzle
Check has been designed to fit on a piece of media that is 42" (96 cm) and is 4.25" (10.8
cm) wide. Since you are likely to print more than one when you diagnose nozzle problems,
make sure your media is wide enough. Calculate the required offset when you print
multiple consecutive nozzle checks, and add the offset to each consecutive print.
Place a piece of Océ I/O paper on the printer table (or use the RMO, if available).
1.
Select the Nozzle Check icon at the right end of the Command Toolbar to place the
2.
nozzle check into the Active Print Job list (you can also add a Nozzle Check to the active
print list when you select it from the Special Prints module).
Confirm media thickness.
3.
Activate the table vacuum (if printing on the table).
4.
Click Print to start.
