Powering

Make sure that the printer is turned off. Connect the power cord to the power supply‘s AC connector and to an electrical outlet. This outlet must have its ground pin connected as shown on the right:

Paper handling

Loading Paper

To insert a new paper roll, please do as follows:

The end of the paper roll must be cut evenly, as shown on the right.

Be sure that the presenter is in the locked position.

Place the spindle in the paper roll’s core and then place the roll and spindle in the paper holder as shown.

Note that the paper must go under the damping device.

Gently push the paper into the paper entrance. The printer will automatically pull the paper, and turn off the Paper LED.

Removing Jammed Paper

Note: If the cutter remains blocked due to a paper jam, unplug the printer and use the manual lever to

move the cutter blade prior to perform the steps below.

If a paper jam occurs, follow the steps below:

• Cut the paper at the paper entrance.

• Unlock the presenter mechanism using the presenter lock.

• Unlock the head up switch raising the print head.

• Gently pull the paper out of the mechanism.

• Lock the head up switch back to initial position.

• Lock the presenter.

Key Panel

The key panel gives visual printer status and manual control to the operator. These functions are accomplished using one switch and LEDs, described below:

• POWER LED: This green LED will be on whenever power is applied to the printer and the power switch is on.

• PAPER LED: This red LED will be on when the printer is without paper. If the print head is up, this red LED will blink.

• ERROR LED: This red LED will blink in error conditions. See ERROR TABLE on page 25.

• PAPER FEED BUTTON: Use to feed paper line by line with fast button touches or feed paper continuously, by pressing and holding down the button.

Presenter operation

The presenter mechanism is responsible for the ejection of the receipts printed by the kiosk printer. It is designed so that paper jam is minimized, especially while in operation. However, due to paper feed conditions (wrong paper feeding, paper wrinkles etc.) paper jam may occur, especially when replacing paper. We may, then, consider the following:

• When a paper jam occurs in the presenter entrance, the paper will not reach the presenter sensor (located in the presenter cover) – in this case, the kiosk printer goes into error condition, thus requiring manual intervention. After removing the jammed paper, the printer must be turned off and on again, in order for the printer to come back on line.

• When the paper jam occurs in the presenter paper exit, the kiosk printer will try to force the paper out for 8 seconds. If that does not happen, the printer will wait for 10 seconds, after which it will try a new paper presenting sequence. If the second try is not effective, the printer will go permanently in error condition, thus requiring a manual intervention to remove the paper. This paper jam may occur while replacing paper or if there is vandalizing of the paper exit. However, to prevent that, the presenter has a clutch device that prevents paper jamming if paper exit is blocked.

Retractable Function

It is possible to set by command the retractable function in the presenter. If this feature is enabled, after a full cut command the presenter will push the paper and return it to its sensor. As a default, if the paper remains above the sensor during 10 seconds, the presenter will pull the paper automatically. The retractable time can also be programmed by command. To enable the retractable function or change the retractable time, please refer section COMMAND TABLE (Operation). The printer is prepared mechanically to pull the paper without any receipt jam.

Reliability of presenter operation without the recommended paper is not guaranteed.

Operation Modes

The printer can be operated in the following modes:

Normal (Remote mode)

In this state, the printer is being controlled by the host through the serial or parallel communication interfaces.

Dump mode

In this mode advanced users and programmers can identify communication problems between the host and the printer or check if a certain programmed data is correctly being sent to the printer, thus being a debugging tool. To start the hexadecimal dumping, turn on the printer while pressing the paper feed switch. A message will be printed on the paper asking you to press once more the paper feed switch if Dump mode is desired, as shown:

- Press PAPER switch once for DUMP MODE

Self-testing

To run a self-test, turn the printer off. Press and hold the Paper Feed switch and turn it on. When the printer starts printing, the paper feed button can be released. A message will be printed asking you to wait the self-test. In the self-test you will find the printer firmware version, among other information.

Communication InterfacesCommunication Interfaces

Communication Interfaces

Communication InterfacesCommunication Interfaces

Communication between a host and the printer can be performed in two communication protocols: Parallel or Serial RS-232, according to the printer model.

Communication cables are not supplied with the printer

Serial Interface

The RS232 serial interface uses a female DB-25 connector. The serial port can operate using the DTR/DSR mode, with 7 or 8 data bits, with or without parity, even or odd parity, one start bit and one or more stop bits. In the RS232 standard, the logic low level corresponds to a +12V voltage level and a logic high level corresponds to a –12V voltage level.

DTR / DSR mode

In this mode, the printer’s DTR line controls the flow of data sent from the host’s TX line and received by the printer’s RX pin. In this case, when the printer’s DTR signal is low (+12V) the printer requests the host to send data. When the DTR signal is high (-12V) the printer tells the host to stop sending data.
