C. Test Print
The test print is divided into two types: engine test print and controller test print.
If an image defect occurred in this printer, make a test print and assess the abnormality of
the printer.
1. Engine test print
Execution of a test print prints the test pint pattern shown in Figure 4-1-3.
The test print procedures are as follows.
1) Load paper into the printer and switch the power ON.
2) When the printer is in the STANDBY mode, press the test print switch (with the arrow point-
ing in Figure 4-1-2, in the hole) with a precision slot head screw driver, and print a test print
(shown in Figure 4-1-3.)
3) Identify the contents of the failure from the test print and rectify the problem according to
the action procedures of image defects. Test pattern can be printed continuously as long as
the test print switch is held down.
Note: Use paper with B5 size or above in width for a test print.
2. Controller test print
Refer to Chapter 1 on Page 1-62 or 1-64.
