OPERA
…
HEXADECIMAL DUMP MODE
“ON LINE” + “POWER ON” (Turn the power on while holding the “ON LINE”
switch depressed)
Each of the signals sent from the computer to the printer will be printed
out in hexadecimal code. This function allows you to check if a control code
sent to the printer by the program being used is correct or not. The buzzer will
sound once to indicate the printer is in hexadecimal dump mode. After the
program has been run, the last line buffer should be flushed by pressing the “ON
LINE” switch. To turn off the mode, it is necessary to turn off the printer
completely.
CLEAR PRINT BUFFER
“FEED” + “ON LINE” + “POWER ON” (Turn the power on while holding both
the “FEED” and “ON LINE” switches depressed)
This operation clears the printer buffer (The buzzer gives two short
beeps). When the printer power is shut off, the data content could degenerate
and become unusable. For this reason, when the printer power is turned off and
there are some left-over in the data buffer or if there is any scramble up in data
receiving, perform the above operation to clear the data in the data buffer. Note
that the data in the buffer can also be cleared by control code <CAN>.
MICRO FEED
“ON LINE” + “FEED” (Press the “FEED” switch while holding the “ON LINE”
switch depressed when the printer is “OFF LINE”)
As a result of this mode, the paper will feed in very small increments.
VALIDATION PRINTING
This printer can print one line of validation printing as described below.
