Check Printhead Nozzle Performance
It is important that nozzle performance is evaluated to determine if the printer is ready for
production. To evaluate the nozzle jetting performance of each printhead the nozzle check print
must be printed.
The nozzle check print shows the performance of each individual nozzle in each color channel.
This information is critical in determining how to proceed in recovering nozzles with Printhead
Maintenance or the optional (AMS).
Procedure
1.
Place a piece of Océ I/O paper on the printer table (or use the RMO, if available).
NOTE
The dimensions of the nozzle check print are 617.3 x 73.7 mm (24.3 x 2.9 inches).
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. Evaluate the nozzle check. In the Nozzle Check print example shown in the figure below, the
Magenta printhead 6 has nozzles that are not firing properly in both Package A and B . It also
shows a new nozzle print after the printheads were cleaned.
NOTE
This is an extreme example to illustrate the problem. In most cases you will likely see
only a small number of nozzles out or misdirected as shown.
