Printing Test
Print Self-test Page
When initially install a printer or any problems happen to the printer, you can make a self-test page to check the
status of firmware version, printer parameter setting, printing quality and related setting information of external
equipment etc. Once you confirm printer does not have any problems after self-testing, please check other devices
or software. Self-testing function is working independently with other devices and software.
To print a test page, check:
1. The printer is connected to the network and that the paper roll is correctly installed.
2. The printer is off and the cover is closed properly.
Hold down the paper feed button, and then press the power button. When the printer turns on, release the power button.
