Using print quality test pages (E220/E321/E323)
To help isolate print quality problems, like streaking, print test pages
using the print quality test pages setting:
1. Enter the configuration menu. See “Using the special
function menu (E220/E321/E323) ” on page 2-106 for more
information.
2. Slowly press and release Cancel three times until the
Ready/Data and Toner Low lights come on and the bottom lights
are off.
3. Press and hold Continue until all lights flash to initiate print
quality test pages.
Three pages print to help evaluate print quality. The first page
has various fonts, the second page is gray, and the third page is
black. Once the paper exits into the output bin, the printer
returns to the home state (four top lights on).
4. Use the test pages to isolate problems such as light or toner
streaks. See the Troubleshooting tables for solutions to these
problems.
5. To exit print quality test pages, turn the printer off.
