CBM-920 User’s Manual 4.3 Panel Opening/Closing 4.3.1 Opening/Closing of Front Panel (1) Applying your finger on the projection on the left side of the front panel, pull it forward when the lock is released. It opens by about 180° centering around the fixed axis. (2) For closing, pressing the front panel, tightly close it until click sound is heard. Also, confirm, on closing, that paper is free of slackening. 4.3.
CBM-920 User’s Manual 4.4 Paper Feeding With the LF switch pressed once, paper is fed by one line. Paper is fed while it is continuously pressed. To feed paper, do not pull it forcibly. Use the LF switch. During pressing the LF switch, the data can not be received. 4.5 Setting Ribbon Cassette (1) Open the ribbon cover. Be sure to turn off power before opening it. (2) In case the paper is out from front cover, cut the paper or remove this paper.
CBM-920 User’s Manual REMARK • • • • 4.6 In case the ribbon cassette is kept setting in printer so long time, there may be the case to make a paper dirty. And in case of continuous printing under low temperature, light print may be occurred due to the characteristic of the ink. Do not conduct printing with no ribbon cassette, this may damage a print head. Replace ribbon cassette before wearing out completely. Use exclusive ribbon cassette. Setting Printing Paper (1) Open the front cover.
CBM-920 User’s Manual (5) Eliminating slack on the printing paper, close the front panel. (6) To change paper, as holding the paper holder in the arrowed direction, re-move the core. Remove, at this time, excessive paper by using the LF switch. After setting the paper, press LF switch once. Then, printer goes to data input printing mode. REMARK • • • • Keep the paper winding direction correct. While in replacing of paper, do not send data from host terminal.
CBM-920 User’s Manual 4.7 Self-Printing Function (1) Test Printing By supplying power as pushing the LF switch, the characters for use, ROM version, DIP switch setting, and model name can be printed. After test printing, perform ordinary operation. By sending RESET signals as pushing the LF switch, perform test printing. During self printing, BUSY signal is being outputted. In this test printing, the following information is printed.
CBM-920 User’s Manual 4.8 Paper Near End Sensor, Paper End Sensor, and Mechanical Alarm 4.8.1 Paper Near End When the paper is getting low, the paper near end is detected and printing is stopped. Power supply to the printing solenoid and motor is immediately stopped and BUSY PE signals are ou tputted to the host. When data still exists in the input buffer, the remaining data in the buffer is printed before stopping. Discharge remaining paper with the LF switch, set new paper and push the LF switch.
CBM-920 User’s Manual 4.9 Auto Loading Function This printer is equipped with function which can automatically load paper. With paper inserted, it is automatically fed by a few lines. When printing paper is diagonally or not properly fed, take out paper softly and insert it once again. If not using this function, cancel this with the DIP switch. Paper insertion is, then, performed with the LF switch. After paper is inserted, with the LF switch pressed and detached, print ready state is created.

CBM-920 User’s Manual • Receiving Control and Buffering The CBM-920, on receiving of print data, performs receiving control (DTR control) in one-word unit. At this time, when the host side has performed data transmit as ignoring DTR, overrun of received data can take place. This state should be avoided by the host side on its own responsibility. (No follow-up can be applied to a data effluent type host.

CBM-920 User’s Manual (10) Defining the download character command (ESC + "&") 1 In case of 24 columns mode By inputting ESC (1BH) + "&" (26H) + A1 + A2 code and the pattern data following after this code, nominated pattern can be registered. Maximum numbers of characters can be registered are 8 characters and this can be registered into the nominated address range between 20H and FFH.
CBM-920 User’s Manual d-2) In case of multi-characters registration By conducting one character registration continuously, 8 characters can be registered at maximum. In case multi-characters are registered into continuous address (character codes), in specifying the address to start registration is A1 and the address to finish registration is A2, maximum 8 characters can be registered.
CBM-920 User’s Manual 2 In case of 40 columns model (ESC + "&" + C1 + A1 + A2) In inputting ESC (1BH) + "&" + C1 + A1 + A2 and the pattern data following after these codes, nominated pattern can be registered. The total numbers of characters can be registered are 224 characters and these characters can be registered into the nominated address between the range of 20H ~ FFH.
CBM-920 User’s Manual In case the following data is transmitted. Since this model is using half dot printing method, this printer can not specifies the continuous dots to the direction of printing direction. (Horizontal direction) Therefore, the pattern can not be registered in the position of "e" mark, even if the pattern is specified in this position. By registration of the data of 2 characters, double width as one character can be compromised.
CBM-920 User’s Manual [Printing of registered characters] In case of printing registered characters, command (ESC + "%" +1) for specifying registered characters is to be conducted initially. Then, by sending 41H and 42H the word of "W" in double width can be printed. Remarks) Even though any data was registered in the upper bit, in case "0" is specified for "C1" parameter, the print result may not be same as the image.
