3.5 Hexadecimal Dump Test Print

The printer has the "on-line" self test function that outputs hexadecimal dump data
when it is connected to a computer.
The hexadecimal dump test is carried out when the printer is on line to print the data
coming from the computer in hexadecimal code (hexadecimal data). Hold down the
POWER button until the beeper sounds 5 times, release the button and set a sheet of
paper in the manual paper feeder to start printing the on-line self test.
Printing starts after the print buffer is full since this mode does not recognize the
control code data as a control code.
