1.
Rewriting the Firmware (ROM) of the Printer
Refer to the following steps for the detailed procedures.
1)
Connect the PC and printer with the USB cable.
2)
Open the front cover, and turn the power supply of the printer on while holding down the Go button. Make sure that the Ready LED is off, and release the Go button. Make sure that all LEDs are off, and press the Go button for two seconds. Then, release the Go button and close the front cover when the Paper LED lights up. These operations make the printer into the PIT3 mode.
3)
Start the PC. When doing this operation at the first time, the Plug & Play program is performed, and the driver is installed.
4)
Open the “hl2000” folder and double-click the FILEDG32 icon to start. Make sure that there is the printer icon of the connected printer, and that no error occurs.
5)
Click the applicable model in FILEDG32 to select.
6)
Drag the firmware (LZ………) in the same folder and drop it onto the icon of the applicable model in FILEDG32.
The files in the firmware are sent to the printer so that they are started to write into the flash ROM automatically. After finishing receiving the files, the printer starts to rewrite the firmware.
The Paper LED blinks irregularly while the firmware being rewritten. Then, be sure not to disconnect the USB cable or to turn off the power supply of the PC before the printer is in the ready mode automatically.
7) Turn the power supply of the printer off.
