Printhead Maintenance
Introduction
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.

Print a Nozzle Check
Introduction
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 automatic
maintenance system (AMS) or with manual printhead maintenance procedures.
Procedure
1. Place a piece of 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 Print icon from the user interface. Input the appropriate settings for
printing (offsets, media thickness, lamp power, etc).
3. Print and evaluate the Nozzle Check Print. The typical procedure for evaluating the nozzle check
print is to closely examine the jetting performance in each jetting package. Circle nozzle outs in
each jetting package with a marker to better evaluate overall performance.
