9.
Print a Nozzle Check to evaluate print quality.
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 36" (91.5 cm) and is 2.125"
(5.4 cm) wide. Since you are likely to print more than one when you diagnose nozzle
problems, make sure your media is wide enough. To calculate the required offset when
you print multiple consecutive nozzle checks, add a horizontal offset of 4.2" or 107.5
mm to each consecutive print.
1.
Place a piece of Océ I/O paper on the printer table (or use the RMO, if available).
2.
Select the Nozzle Check icon at the right end of the Command Toolbar to place the
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).
3.
Confirm media thickness.
4.
Activate the table vacuum.
5.
Push the printer Start button to begin the print.
6.
Print an image to make sure there is no banding or other print quality issues.
How to Evaluate a Nozzle Check
1. The Magenta section of the Nozzle Check print example shown in the figure below indi-
