Using print quality test pages (E320/E322)
To help isolate print quality problems, like streaking, print test pages
using the print quality test pages setting:
1. Enter the special function menu. See “Using the special
function menu (E320/E322) ” on page 2-105 for more
information.
2. Press and release the operator panel button twice quickly
(double-button press) four times until the Ready/Data and Toner
Low lights come on and the bottom two lights blink.
3. Press the operator panel button with a long button press (hold
until all the lights come on) to initiate print quality test pages.
Three pages print to help evaluate print quality. The first page
has registration marks, the second page is gray, and the third
page is black. Once the paper exits into the output bin, the
printer returns to the
Ready
state.
4. Use the test pages to isolate problems such as light print or
toner streaks. See the Troubleshooting tables for solutions to
these problems.
5. To exit print quality test pages, press the operator panel button
with a long button press (hold until all the lights come on).
