10 Key Functions
Description of the Key Functions
The keys can have different functions depending on the status – normal operation or print settings menu.
The time for which the button is held down is also an issue.
FEED / Enter (6)
Through this key, the printer can be reactivated from sleep mode, and the paper can be transported forward.
When the feed key is pressed, the printer will first feed one line of the set font. If the key is held down for more
than 2 seconds, it will feed continuously.
Self Test
With a self test, the inner function of the printer is tested by starting a printout. For this, the paper feed button (6)
{FEED} is held down for at least 3 seconds, while the printer is being reactivated from power-off. The interfaces
are not checked at this time. The software version and the character set are printed. For OEM, special printouts
can be activated during a self test.
OFF / NEXT Key (3)
By holding down the OFF/NEXT key for more than 3 seconds during operation, the processing of batch file T2 is
initiated. In µ-P flash, the command for power-off (after 1 second) is filed in batch file T2. This way, this key is
programmed as an OFF button for the printer (controller with power-off mode).
