Test Print

Overview

Printing test pages helps determine if the printer is functioning.
CAUTION:
There are two types of test pages: engine-test page and Main Controller-test page. Print a test page to make sure the
printer engine and the Main Controller are functioning.
■ Engine Test Print
Press the button inside the Rear Cover to print the test pattern on one side of a sheet of paper. Hold down the button to start
continuous test print, and release the button to end it.
The image of the engine test print (Test Print C) is recorded in the DC Controller. Because of this, it can be output even if the
Main Controller is faulty.
Test Print C Pattern
■ Controller Test Print
Data of the controller test print is created inside the Main Controller. When no image failure is found in the test print in normal
output mode, it is assumed that the failure is caused by the PDL input.
NOTE:
Method to display the test print: It appears in the menu by pressing [Job Status/Cancel] key and [Utility] key simultaneously.
