5.1.2. Installation
- PRINTER: connect the power cable to printer and the RS232 interface special connection cable between printer
and message display unit.
- INK CARTRIDGE: the printer is normally supplied complete with an ink cartridge and paper roll already
installed. The ink cartridge will print approximately 10,000 lines with 20 characters per line, keeping writing
perfectly clear for reading throughout.
The ink cartridge is very easy to replace observing the following steps:
1) remove paper; usually the ink cartridge is replaced together with the paper roll; if for any particular reasons it
is necessary to replace only the cartridge and not the paper roll, then you should cut the paper.
2) take out the used cartridge by pushing the left end at the point marked with the word "PUSH ".
3) insert the new cartridge applying a slight pressure.
After cartridge insertion, the ribbon might not be perfectly settled, in this case, it is sufficient that the printer feeds
the paper on a few times.
- PAPER ROLL INSTALLATION: the insertion of a new paper roll should be carried out with printer on and with
the front panel open. The operation sequence is the following:
1) remove the written paper roll.
2) bring paper from the new roll to the printing mechanism opening.
3) press the paper feed button until paper comes out of the printing mechanism.
4) insert the new roll in its compartment and close the panel.
The printer ST40 prints on standard paper, easy to find on the market.
Paper specifications are listed in the chapter "TECHNICAL FEATURES ".
It is also possible to order paper from CET.
- SELF-TEST: the printer ST40 can easily carry out a self-test to check printer status.
To run the self-test, switch on the printer while keeping the paper feed button pressed.
The self-test consists in printing 6 lines using the 4 different writing formats supported by the printer ST40.
We recommend to always carry out at least one self-test upon printer installation to check printer condition and
familiarise with the writing formats supported by the printer ST40.
