User manual CITIZEN SLD-366

[. . . ] This product should never be placed near or over a radiator or heat register. This product should not be placed in a built-in installation unless proper ventilation is provided. l This product should be operated from the type of power source indicated on the marking label. If you're not sure of the type of power available, consult your dealer or local power company. [. . . ] For replacing roll paper, set print head at head up condition, and remove the paper which remains in printer unit carefully by turning paper feed knob. CITIZEN 20 3. 7 Removing paper jam and canceling cutter lock Remove paper jam or cancel cutter lock by following the procedure explained below. (1) Open front cover (2) Put mechanism lock lever inside of main body, pull down printer mechanism. To pull out the paper from printer mechanism, pull it out carefully at head up condition. (4) Canceling cutter lock Remove paper inside of paper cutter and turn ON power. In case cutter blades to home position and carries out initializing, cutter lock was cleared completely. In case cutter does not return to home position or occurs some error again, turn OFF power, turn the knob which locates on left bottom side of auto cutter to the front side as shown in the below, then return cutter blade manually and remove the paper inside of auto cutter. (5) After fixing the problem, pull down head up lever and return printer mechanism to its home position. !Caution : As print head and motor are hot, do not carry out this action right after printing. For removing the remaining paper, do not touch the surface of print head and motor. 3. 8 Self print function By supplying power as pushing FEED switch or send RESET signal to this printer, type of characters which is used, ROM version and DIP switch setting etc are automatically printed. 3. 9 PE and Mechanical alarm 3. 9. 1 Paper end (PE) This sensor detects the existence of paper. Printer stops printing when roll paper runs out, outputs BUSY and PE signal and lights up PAPER lamp. Serial interface equips a driver and receiver of RS-232C, make sure to use it at RS-232C level. In case they are used, they may cause abnormality or break control board. 6 Parallel Interface 6. 1 Specifications Data input method Control signals : 8 bit parallel signal (DATA0 - 7) : ACK, BUSY, STB, FAULT, PE, RESET 6. 2 Explanation of input / output signals DATA0-7 STB RESET ACK BUSY FAULT PE : 8 bit parallel signal (Positive logic) : Strobe signal to read 8 bit data (Positive signal) : Signal to reset control board : 8 bit data request signal. Pulse signal output at the end of the BUSY signal (Negative logic) : Signal to indicate BUSY state of the printer. Input new data for "LOW" (Positive logic) : Signal which is made "LOW" when printer is in alarm state. (Negative logic) : Signal which is output when paper runs out. (Positive logic) CITIZEN 25 6. 3 Electrical characteristics (1) Input Signal Level All the input signals are at TTL level. "HIGH" level : 0. 7Vcc MIN "LOW" level : 0. 3Vcc MAX (2) Output Signal Level All the input signals are at TTL level. "HIGH" level : Vcc ­ 0. 1V MIN "LOW" level : 0. 1V MAX (3) I/O Conditions Input signal of STB and RESET are pulled up by 3. 3K Ohm. Others are pulled up by 50K Ohm. <Printer side> <Host side> All the output signals are pulled up by 50K Ohm. CITIZEN 26 6. 4 Timing chart (1) Data Input and Printing Timing ACK is not outputted. TYP : 500 ms MIN (On supplying power) 6. 5 Data receiving control When BUSY signal is "LOW", data from the host can be received. Due to this large buffer, host side is released immediately. CITIZEN 27 7 Serial Interface 7. 1 Specifications (1) Data transfer system: Asynchronous (2) Baud rates 1200, 2400, 4800, 9600, 19200 bps (Selectable by user) (3) Configuration of one word Start bit : 1 bit Data bit : 8 bits Parity bit : Add/even or no parity (Selectable by user) Stop bit : 1 bit or more (4) Signal polarity RS-232C l Mark = logic " 1" (-3V - -12V) l Space = logic " 0" (+3V - +12V) (5) Receiving data (RD signal) RS-232C l Mark = 1 l Space = 0 (5) Receiving control (DTR signal) RS-232C l Mark : Data transfer not available l Space : Data transfer available (6) Transmission control (TD signal) DC1 code (11H) X-ON : Data reception available DC3 code (13H) X-OFF : Data reception not available CITIZEN 28 7. 2 Explanation of Input / Output signals 7. 2. 1 Input / Output signals (1) RD Serial receiving data signal. On occurrence of framing error, overrun error, or parity error, the data is printed as "?". When they are written in BUSY, overrun error is occurred and data is ignored. Further, BUSY can take place on supply of power, during test printing, during on-line, or on resetting. [. . . ] l The numbers of dots are n1 x 8 in horizontal direction and n2 x 8 in vertical direction. l The download bit image thus defined remains effective until redefinition, ESC @ execution, ESC &, or power OFF takes place. l A download character and a download bit image cannot be defined simultaneously. With this command executed, defined content of a download character is cleared. [. . . ]
