APPENDIX 3 INSTALLING THE MAINTENANCE PRINTER DRIVER
To identify terminals connected via USB interface, the PC requires the corresponding 
virtual USB devices to be implemented by driver.  If you connect any number of the printer 
to your PC, therefore, the same number of virtual USB devices will be automatically 
configured on your PC.  To prevent virtual USB devices from being configured limitlessly, 
use the unique driver installation procedure described below that enables your PC to 
identify terminals via single virtual USB device.
(1) Check that the power switch of the printer is turned off. Disconnect the USB cable that 
connects the printer with PC.
(2) Turn on your PC.
(3) Open the front cover, and turn the power supply of the printer on while holding down 
the [Go] button. Make sure that the Toner/Drum/Error LED lights up.
(4) Release the [Go] button, and then make sure that all LEDs are off.
(5) Press the [Go] button for the 2 seconds, and the Error LED lights up.
(6) Click the “maintenance.exe” of the Printer Maintenance Driver which has been copied 
in the “hl2200” folder to start.
