Engine Test Print

This machine has an engine test print function to check whether the printer engine is operating normally.

NOTE:
The engine test print can be performed by using only the DC Controller. Therefore it can be output even when the Main Controller is failed.

There are two types of engine test print: 1-sided print and 2-sided print.

1. Load A4/LTR paper in the cassette.
2. While the machine is in the standby mode, open and close the Cartridge Door for the predetermined number of times in a row.
   • In case of 1-sided print 4 times
   • In case of 2-sided print 5 times or more
3. An engine test print is executed, and the test pattern as shown below is printed on one side or both sides of a sheet of paper.

Controller test print

The following test print types are available with this machine, and you can check for failure of an image with a circle 'Yes' described in the image check items in the table below. When no failure is found in the test print in normal output mode, it can be caused in PDL input or Reader. The image of the test print is generated by the Main Controller PCB.
