CHAPTER 4
V. IMAGE DEFECTS
A. Test Print
This printer is capable of executing test prints of two types: engine test print and controller test
prints.
When an image defect appears, a test print can be made to identify the problem.
1. Engine test print
Test print patterns of horizontal lines are printed in this test print. The test prints can be made by
using the printer driver checker which can make all four test patterns (vertical lines, horizontal
lines, solid black and solid white), or the test print switch located on the right side of the printer
(see Figure 1-4-1).
One print of test pattern can be made by pressing the switch once when the power is turned ON
and the "READY" appears on the display. If the switch is held down, test prints are made
continuously.
Make sure that paper is loaded into the lower cassette before pressing the switch as this is where
the paper is fed from.
