Solid Color Test; Solid White Test - Lexmark Optra C Service Manual

5045-001

Solid Color Test

This test indicates which cartridge(s) is/are contributing to
background problems. It also shows which of the four cartridges has
reached end-of-life. The test produces a solid band of each color,
approximately 2 1/4 inches (60 mm) long. Each color should be a
uniform color with no vertical streaks. If streaks are present, replace
the cartridge. Cartridges that streak contribute to background.

Solid White Test

This test shows the amount of background. Background is most
visible as a white border 5/16 inch (8 mm) from the top edge of the
paper. Background is possible in any color (or combination of
colors), although it appears gray to the naked eye. Although a worn
photoconductor contributes to background, background is primarily
due to a cartridge condition. Photoconductor scratches show as a
black vertical line.
