Star Micronics SP300 Series manual Micro Feed

2<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.

3<CLEAR PRINT BUFFER> (Single Head Only)

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 DIP switch 1-7 of this printer is set to ON (which is the factory presetting), the RAM back-up function operates to maintain the data in the data buffer, even if the power for the printer is shut off due to power failure, etc.

However, when the printer power is shut off for more than 10 hours, the data content will become unstable and its content could degenerate and become un- usable in the worst instances. For this reason, when the printer power is turned off for more than 10 hours, 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>.

4<MICRO FEED>

ON LINE + FEED Press the FEED switch while holding the ON LINE switch depressed when the printer is OFF LINE and the paper will feed in very small increments.
