17: Cyan Solid Fill

This prints shows uniformity of fill.
Look for: Even, uniform fills throughout the
print. There should be no wrinkling or deformity
of the paper throughout the print.
Causes: Weak jets or uneven drum heating
may cause uneven fills.
To solve wrinkling, try different print media.
Replace the drum maintenance tray to correct
streaking.
Check the drum-temperature sensor for debris
build-up on the sensor. Or the sensor is in
improper contact with the drum. Refer to the test
print Reverse Text.
The transfix pressure may be incorrect. Perform
the transfix spring adjustment described in
"Transfix roller pressure spring adjustment", on
page 4-154. As a last resort, replace the
drum/transfix assembly.
