Please note: the parameters marked with the symbol D represent the default values. (2) N.B.: parameter valid only wth 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. (3) N.B.:This parameter is displayed if the printer has an USB interface. The Status Monitor is an additional printing driver component that allows the printer status monitoring. (4) N.B.: If paper is present on the ejector and if this parameter is desabled, the printer can t perform the paper retract; if this parameter has been activated in No Timeout mode, when the printer receives the command, it can retract the paper; if this parameter has been activated in T.out sec-2 min mode, the printer executes automatically the paper retract after seconds or 2 minutes. (5) N.B.: if this parameter is desabled, the printer can t perform the automatic ejecting; if this parameter has been activated in T.out sec-2 min mode, the printer executes automatically the automatic ejecting after seconds or 2 minutes. (5) N.B.: Function, if enabled, allows to prevent the deterioration of dots stressed with special print-outs like graphics, tables and similar. (7) N.B.: 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. (8) N.B.: Function, if enabled, allows to print ticket more short than 150mm (see the paragraph 4.1 technical specifications). 1-5

20 1. INSTALLATION AND USE The settings made are stored in EEPROM (nonvolatile memory). During power-up, if the FORM FEED key is held down, the printer enters the autotest routine and prints out the setup report. The printer will remain in standby in Hexadecimal dump mode (see section 1.5) until another key is pressed or characters are received through the printer communication port. 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. 1.5 HEXADECIMAL DUMP This function is used to display the characters received from the communications port; the printer prints out both the hexadecimal code received as well as the corresponding ASCII code. Once the autotest 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 (204 dpi version) or every 32 characters received (3 dpi version), it prints hexadecimal values and ASCII codes (if the characters appear underlined, it means the receive buffer is full). Shown below is an example of a Hexadecimal Dump for the 3 dpi (32 characters) version: (Fig.1.7) HEXADECIMAL DUMP ASCII DUMP 0x D 61 6C D E F 6E Hexadecimal dump function x A 6B 6C 6D 6E 6F A 2E 6789abcdefghijklmnopqrstuvwxyz. 1.6 MAINTENANCE Changing the paper roll Every paper change verify that there aren t paper off-cuts from the paper inlet and outlet; if this event happens remove the paper off-cuts before execute any other operation. To change the paper roll, proceed as follows: 1) Position the paper roll (1) so that it unrolls correctly as shown in fig.1.8; 2) Insert the end of the paper roll in the paper load opening on the printing mechanism (2) and wait for the paper to load automatically (see fig. 1.8); 3) Remove the paper from the paper exit opening (3) (6). (6) N.B.: The paper exit opening may be assembled in one of two positions, depending on the model in use (see fig. 1.8). 1-6

24 1. INSTALLATION AND USE Paper jam In the event of a jam along the paper path, proceed as follows: turn the printer off and on, before removing the paper, in order to cut the paper and attempt to have it ejected. If this does not solve the problem, proceed as follows: Paper jammed on ejector (see fig. 1.15): 1) Lift the roller cover (1). 2) Remove any pieces of paper present in the ejector rollers (2). 3) Remove any paper present in the paper exit opening (7). (7) N.B.: The paper exit opening may be assembled in one of two positions, depending on the model in use (see fig. 1.8). The area marked by a dotted line (2) indicates that area of the ejector roller unit in which the paper could jam (Fig.1.15) Paper jammed inside the printer perform the operations below: 1) Lift up the print head using the opening slot (1) located on the cover (see fig. 1.16); remove any pieces of paper. 1-10

25 1. INSTALLATION AND USE 1 (Fig.1.16) 2) Open (8) the lateral cover (1) rotating the lock/unlock button (2) with the screwdriver or coin (see fig.1.17). (8) N.B.: To close lateral cover, once reassembled it, push the the lock/unlock button. (Fig.1.17)

26 1. INSTALLATION AND USE Extract the cover unit pulling from the bottom to the outside and then lifting up to release the two slots (see fig.1.18). (Fig.1.18) 4) Pulling up the cutter as shown in the fig. 1.19; remove any pieces of paper. (Fig.1.19) ATTENTION Remove the cover before pulling up the cutter. 1-12

27 1. INSTALLATION AND USE Cleaning the printing head WARNING 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. The printer must be turned off when the printing head unit is removed. Turn off the printer and proceed as follows: 1) Lift up the printing head using the opening slot (1) located on the cover, as shown in the fig. 1.20; (Fig.1.20)

28 1. INSTALLATION AND USE 2) Clean the printing head heating line (1) using a non-abrasive cloth moistened with denatured alcohol (see fig. 1.21) (Fig.1.21) Clean the heating line (black line indicated by the arrow) 1 3) Lower the cover (1) to close and pressing (2) in the exact point indicated from the label located on the cover as shown in the fig and (Fig.1.22) (Fig.1.23) 1-14

29 1. INSTALLATION AND USE Cleaning the ejector rollers WARNING The printer must be turned off during cleaning operations. Caution during cleaning operations to tilting paper holder(3). Turn off the printer and proceed as follows: 1) Lift up the roller cover (1) as shown in fig ) Clean the rollers (2) using a medium-stiff brush to avoid them being scratched. (Fig.1.24)

If C2 < C1, the command is not executed. d is the dot data for the characters. The dot pattern is in the horizontal direction starting from the left. Any remaining dots on the right remain blank. The data to define a user-defined character is ( x x y) bytes. To print a dot, set the corresponding bit to 1; to not have it print, set to 0. This command can define different user-defined character patterns for each font. To select the font, use ESC!, ESC.
