Notch Distance [mm]• (6):0D.
Print Density:• -50%, -37%, -25%, -12%, 0%D,+12%, +25%, +37%, +50%.
General notes: The parameters marked with the symbol Dare the default values.
Settings remain active even after the printer has been turned off.
Nota(1) Parameter valid only with serial interface;
Nota(2) Parameter valid only with serial interface; using this parameter, it is possible to select whether the Busy signal is activated
when the printer is both in Off Line status and the buffer is full, or only if the reception buffer is full.
Nota(3) This parameter is used to identify univocally the USB printer by a numerical address code, if on the PC are connected
two printers that are the same models for example two USB printers.
Nota(4) The Status Monitor is an additional printing driver component that allows the printer status monitoring. It must be enabled
only if it was installed the Status Monitor specific driver.
Nota(5) Function, if enabled, allows to prevent the deterioration of dots stressed with special print-outs like graphics, tables and
similar.
Nota(6) The parameter “Notch distance” is displayed and enabled only in case that the notch alignment parameter is enabled.
The parameter “Notch distance” is used to set the exact distance of the notch entering the desired value in millimetre
and in deci-millimetre.
When the FORM FEED key is pressed, the printer enters parameter configuration.
When the LINE FEED key is pressed, the printer exits setup and terminates the Hexadecimal dump function.
When the receive buffer is full, if handshaking is set to XON/XOFF, the printer sends the XOFF ($13) on the
serial port.
When the receive buffer has cleared once again, if handshaking is set to XON/XOFF, the printer sends the
XON ($11) on the serial port.
The settings made are stored in EEPROM (nonvolatile memory).
2.4 Hexadecimal dump
This function is used to diagnose the characters received through the communication port; the characters are
printed out both as hexadecimal codes and ASCII codes (see Fig. 1.4). Once the self-test routine has finished,
the printer enters Hexadecimal Dump mode. The printer remains in standby until a key is pressed or characters
are received from the communications port; for every 24 characters received, it prints hexadecimal values and
ASCII codes (if the characters appear underlined, it means the receive buffer is full).

WARNING
Make sure no water or other liquids seep inside the printer.
BEWARE
Before any type of work is done on the machine, disconnect the power supply cord from
the mains outlet.
ATTENTION
Do not touch the head heating line with bare hands or metal objects. Do not perform any
operation inside the printer immediately after printing because the head and motor tend
to become very hot.
2.6.1 Paper load specifications
