2: X-Axis Motion (Drop Mass
Evaluation)
For X-Axis Motion problems, see Service Test
Prints 13-19 (solid fill prints).
This print is used by Engineering and
Manufacturing.
The print must be printed on Xerox Photo
Paper.
Using a lower grade paper results in inaccurate
measurements.
3: Color Bands, RGBK Dither
The large, secondary colored areas in this print
reveal banding and weak jets.
Look for:
These are vertical “bars” or “bands”
of much lighter color or a different hue running
in-line in one or more of the solid fills.
Causes:
A weak jet can cause banding; see
the Weak/Missing Jets test print (on
page 5-35). Banding can also be caused by
color-to-color misregistration.
Use service diagnostics to ensure that the
printhead and drum thermals are correct.
Follow the instructions on the “Printhead
Troubleshooting Checklist”.
