Frequently Asked Questions - CBM-920 CITIZEN

How do I load paper into the CBM-920 printer?
Open the front cover. Cut the paper edge straight. Insert the paper into the paper inlet. If auto loading is enabled (DIP switch setting), the paper will feed automatically. If not, press the LF switch to feed paper. Close the front cover and press LF switch once to enter print mode.
How do I replace the ribbon cassette?
Turn off the printer. Open the ribbon cover by pulling the left side forward. Remove the old cassette by pulling the 'PULL' part. Insert a new ribbon cassette with the correct orientation, turning the knob to remove slack. Close the ribbon cover. Do not print without a ribbon to avoid damage to the print head.
What should I do if the paper jams?
Turn off the power immediately. Gently pull out the jammed paper slowly in a straight direction. Do not pull in reverse. Check for any foreign objects. If the problem persists, contact service personnel. Ensure paper is properly aligned when reloading.
How do I perform a self-test print?
Hold down the LF switch while turning on the power. The printer will output a test print showing the ROM version, DIP switch settings, international character set, and other parameters. Release the LF switch after printing starts.
How do I set the DIP switches for baud rate and international characters?
The DIP switches are located on the printer. DS1 switches 1-3 set international character, DS1-6 enables paper near end, DS1-7 enables auto loading, DS1-8 enables hex dump (40 cols only). DS2 switches set serial parameters: DS2-1 bit length, DS2-2/3 parity, DS2-4/5 baud rate. Refer to the manual for exact switch positions.
What interfaces are available on the CBM-920?
The printer supports either a serial interface (RS-232C) or a parallel interface (Centronics). The interface type is indicated by the model suffix: 'R' for serial, 'P' for parallel. The connector is a 20-pin Hirose type.
The printer is not printing. What should I check?
Check the power supply (DC 5V, 2.5A). Ensure the interface cable is connected properly and the host is sending data. Verify paper is loaded and not jammed. Check if the printer is in BUSY state (paper end or mechanical alarm). If the PE lamp is on, replace or feed paper. For mechanical issues, turn off power and contact service.
Can I use thermal paper with this printer?
No, the CBM-920 is an impact dot matrix printer that uses standard roll paper and ink ribbon. It is not designed for thermal paper. Use paper of recommended weight (45-55 kg/1000 sheets) and avoid carbonless multi-ply paper thicker than 0.13 mm.
How do I clean the printer?
Turn off the power. Clean the platen (rubber roller) with a cotton pad dipped in ethyl alcohol. Wipe the outer case with a soft damp cloth. Do not use thinners, benzene, or chemical cleaners. Internal cleaning should be done by service personnel at least once a year.
What does the hex dump mode do and how do I enable it?
Hex dump mode prints all data received from the host in hexadecimal format, useful for debugging. It is available only on the 40 columns model. Enable it by setting DIP switch DS1-8 to ON and power cycling. To return to normal mode, set DS1-8 back to OFF and power cycle.

This mode can be available by turning ON the Dip Switch DS1-8.

After Power is ON (after printing, if self print is conducted), this mode is available.

This mode can be kept until Power is OFF.

To change to normal print mode, turn Power OFF after turning Dip switch DS 1-8 OFF, and then turn Power ON.

This function is only available for 40 columns model.

This function is not available for 24 columns model.

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 outputted 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. Then normal print mode is created after cancellation of BUSY and PE output.

This function can be selected by Dip Switch setting.

4.8.2 Paper End

Whether there is printing paper or not is detected. With printing paper running out, printing stops and BUSY and PE signal is outputted.

Printing is also stopped even when data remains in the input buffer.

Discharge paper with the LF switch, set new paper and push LF switch. Then BUSY PE is canceled.

When auto loading function is available, printer automatically feeds recording paper at a few lines by inserting the recording paper into the paper inlet.

4.8.3 Mechanical Alarm

When occurrence of trouble in the mechanism is judged by locking of the motor, power supply to the printing solenoid and motor is stopped and BUSY signals as well as FAULT signals are output to host terminal.

To recover from alarm state, after removing trouble causes, either re-supply power or input RESET signals.

For severe trouble, turn power off and leave this repair to service personnel.

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.

6.3 Explanation of Input/Output Signals

1) I/O Signals into Printer (RS-232C)

• T · D (TRANSMIT DATA) Serial transmit data signals
• R · D (RECEIVE DATA) Serial received data signals.
• DTR (DATA TERMINAL READY)

When this signal is in Ready (space), send data or a command.

If sending takes place in Busy (mark), overrun error is occurred.

Even in printing, data can be sent into the input buffer. If this signal is in Ready.

Further, Busy takes place also on supply of power, in test printing, on-line status or on occurrence of resetting.

2) Input Signals into Printer

RESET..... Signal to reset the whole printer (negative logic) 4 ms or more

3) Output Signals from Printer

6.5 Error Detection

- Communication Error

1) Parity Error In checking of odd/even parity based on parity checking assignment, when parity is found nonconforming.
2) Framing Error In detection of stop bit when space state has been detected.
3) Overrun Error Regardless of data being held in receiving buffer register, when next data are transmitted to the receiving buffer register.

On occurrence of the above mentioned error, the data concerned is converted into '■' (7FH) which is printed.

• 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.)

8.2 Input data format

(1) Line feed command after printing (CR, LF)

By inputting of CR (0DH) code, printer prints the data in print buffer. In case there is no print data in print buffer, only linefeed is performed. And this command is ignored by being ignored by DIP switch setting.

For example) 24 columns model

123456789012345678901234CRLF

(2) SI, SO and US, RS command

In case the 8 bit data is specified (data bit length of serial communication), the function of SI and SO codes is same as the function of US and RS. But in case 7 bit data is specified, SI, SO works for specifying of SI side (characters from 20H to 7FH) and for specifying of SO side (characters from A0H to FFH)

①Standard character specifying (SI, US) command By inputting SI (0FH) and US (1FH) codes, printer cancels the double wide characters and the data after this command is printed in standard characters. The characters can be canceled by this command is only double wide character, double wide and double high character can not be canceled.
②Double wide character specifying (SO, RS) command By inputting SO (0EH) and RS (1EH) into the nominated columns, the data after this command is printed in double wide character. This is canceled by line feed operation or inputting SI or US command. Although both of standard character and double wide character can exist in one line.

When the total characters goes to 24 (40) columns on the basis of calculation at standard character basis, printer performs automatic printing (buffer full printing)

S O1 2 3 4 5 6 7 8 9 0C R
S O1 2 3S IA B C DC R
S O1 2 3S IA B CS O12C R
AS O1 2 3 4 5 6 7 8 9 0 1 B

1 2 3 4 5 6 7 8 9 0 1 2 3 ABCD 1 2 3 ABC 1 2 A 1 2 3 4 5 6 7 8 9 0 1 B Mixed printing Although the last character is specified at double wide character, this is 24th columns and only this character is printed at standard character. (In case 40 columns version, this may happen at 40th columns.)

(3) Data cancellation (CAN) command

In inputting of CAN (18H) code, all of the data before CAN code at same one line is canceled.

SO123456CANABCCR

A B C * "SO" command is not canceled and "123456" is canceled. Therefore, "ABC" are printed at double wide characters.

(4) Inverted character specifying (DC2) command

By inputting data adding DC2 (12H) into the beginning of the line, (in case of adding this command into the position except for the beginning of line, this command is ignored.) all of the data after this command is printed at inverted character.

Cancellation of inverted character is conducted by inputting DC2 again or DC1 (initial setting).

In case inverted character is specified by dip switch setting, all of this operation goes to opposite way.

(5) Initial set (DC1) command

By inputting DC1 (11H), each condition specified after power is ON is canceled and printer goes to initial condition same as the condition right after power is ON.

But, the data in input buffer is not changed.

(6) Continuous line feed specifying (ESC + "B" + n)

By inputting ESC (1BH) + "B" (42H) + n code, printer performs continuous line feeding at n dot lines.

But, n is to be within 4 ≤ n ≤ 255 and must be even number. In case odd number is specified for n, this is to be concerned as even data of "n - 1".

And in case that n is specified at the out of available range, this command is automatically ignored.

When inputting this command, in case there is some data in the input buffer, printer prints the data. But the printed line (10 dots line) is included in the volume of line feed n. Therefore in case n is 4 ≤ n ≤ 9 line spacing may go to "0".

(7) International character specifying command (ESC + "R" + n)

By inputting ESC (1BH) + "R" (52H) + n code, the character after this command is set at the characters table of specified country.

The value of n and setting of each countries

n Country n Country
0 U.S.A. 5 Sweden
1France6Italy
2Germany7Spain
3 U.K.8 Japan
4Denmark

Remarks: In case the value of n is out of the above range, Country is set automatically at U.S.A.

When power is ON, initial setting varies depending on Dip Switch setting.

(8) Registration of sentence command (ESC + "/" + n)

By inputting ESC (1BH) + "/" (2FH) + n 'Registration of sentence' command, the data of 24 (40) bytes following after n is registered.

The data between 1 to 8 is to be specified as the data for n.

In case that the data of n is specified out of this range, the data following after this command is recognized as normal print data, the registration is not conducted and printer prints the data immediately.

In case the registered data already exists at n, previous data is automatically canceled and new data is overwritten.

The total of this data must be below one line and the end of this data must be finished by CR (0DH) or LF (0AH).

In case the data over 24 (40) is registered, although the data below 24 (40) can be registered properly, the data over 24 (40) is printed as normal print data.

ESC command can not be registered.

(9) Printing registered sentence (ESC + "!" + n)

By inputting ESC (1BH) + "!" (21H) + n, printer prints the sentence registered at the value specified by n.

The data between 1 and 8 is to be specified for n. In case the data is registered out of this range, this transaction is not conducted.

Remarks 1) Although the data can be registered at 24 (40) bytes, in case the data goes over 24 (40) columns (for example, in case double width or double width and double height is specified in this registration.) Printer prints the data by 24 (40) columns and the columns over 24 (40) columns is fed to the next line. Make sure to register the characters concerning the actual print results.

Remarks 2) In case double wide and double high or inverted characters are specified in this registration, as far as this setting is not canceled, printer prints the data following this setting.

Example 1)

ESC/1This is a pen CR...... Sentence is registered to 1.
ESC/9Is This a pen?CR ...... can not be registered to 9.
ESC/It is a penCR...... The registered sentence is overwritten on the sentence registered in previous 1.
ESC!...... prints the sentence registered in 1.

Although normal printing was requested with no specifying print condition, printer prints the data following print condition of double wide and double high characters due to the previous print condition was not canceled.

(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.

Make sure that in case new data is registered to the address range already has old data, the old data is automatically overwritten and new data is registered.

Furthermore, in case the data over 8 characters is registered, all of the previous data is cleared automatically.

[Specifying address]

The specified address conforms to the character codes and these characters can be accessed as well as the internal characters after registration.

In case any internal characters already exists in the address specified for registered characters, the internal characters are replaced.

A1 means the address of start to be registered and A2 means the address of finish to be registered.

[Data transmission method]

d-1) In case of one character registration The address is to be specified from the 20H \~ FFH, then the specified address is considered as A1. In case of one character registration, the address of start and finish are to be same. Therefore, A1 = A2.

One full dot pattern of 6 · 8 dots matrix is registered to address 41H. (The code of internal character "A".) (Number is Hex. Mode.)

$$ \mathrm{ESC} +" \ & " + \mathrm{A1} + \mathrm{A2} +" \text { Pattern data(6bytes) }" $$

IB 26 41 41 FF·FF·FF·FF·FF·FF

After the above control, in case the character code of 41H is specified, full dot printing of 6 · 8 dot matrix printing is performed. (Character "A" can not be accessed to.)

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.

[Configuration of pattern data] In case of 24 columns model

The pattern data to be registered for one character is 6 byte. This means the pattern comprises 6 · 8 dots matrix is decomposed to 6 portions divided to the direction of lengthwise. The data of 6 bytes in total is to be transmitted as each one bytes data.

In case the following pattern file is transmitted.

Upper data (LSD) Lower data (MSD) 1 2 3 4 5 6 → 1 2 3 4 5 6 63H 55H 49H 41H 41H 41H Pattern data (6 bytes)

[Print of registered characters]

In case of printing the registered characters, these characters are printed by command (CR, LF, ESC + "B" + n) at same print condition as the other internal characters.

② In case of 40 columns model (ESC + "&" + Cl + 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.

But in case new pattern is registered into the address has already old pattern, the old data is automatically cleared and new pattern is registered.

[The upper bit use ]

The data is specified in parameter C1 to recognize whether the registered character is using the upper bit or not.

C1 = 0 (00H) : The upper bit is not used.

C1 = other than 0 : The upper bit is used.

Even if the upper bit is used, 0 is specified in this parameter, in case of double width and double height character, the highest dot is missing and proper print result may not be conducted.

[Specifying address]

A1 : Start of the registration address (20H \~ FFH)

A2 : End of the registration address (20H \~ FFH)

[Configuration of pattern data]

The pattern data to be registered for one character is 9 byte.

This means the pattern comprises 9 × 8 dots matrix is decomposed to 9 portions divided to the direction of lengthwise and the data of 9 bytes in total is to be transmitted as each one bytes data.

In case the following data is transmitted.

The lowest bit (LSD) The highest bit (MSD) 1 2 3 4 5 6 7 8 9 → 1 2 3 4 5 6 7 8 9 Pattern data (7 bytes)

Since this model is using half dot printing method, this printer can not specify 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.

After following the code of ESC + "&" + 01H (Remarks) + 41H + 42H, by sending the following date,

Date 07H, 08H, 10H, 20H, 40H, 80H, 40H, 20H, 1CH

20H, 40H, 80H, 40H, 20H, 10H, 08H, 07H, 00H

the character of "W" in double width can be registered in the area of 41H and 42h.

[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.

(11) Download character valid/invalid command (ESC + "%" + n)

By inputting ESC (1BH) + "%" (26H) + n codes, selection of valid or invalid of registered characters is performed.

N = 1 (01H) : Enable the registered characters.

(In case there is no change in the registration address, internal characters are printed.)

N = 0 (00H) : Disable the registered characters.

Internal characters are print.

Initial setting is for printing internal characters.

Even though any characters were registered by command, in case the above setting is "disable", the registered characters can not be printed.

Remarks ) This command is available only for 40 columns model.

(12) Bit image printing command (ESC + "K" + n1 + n2 + n3)

By inputting ESC(4BH) + "K" + n1 + n2 + n3 code, text mode is changed to bit image mode, n1, n2, n3 specify the volume of bit map data to be transmitted after this command.

Therefore, n1 shows the number of bytes to the direction of side, n2 (lower) and n3 (higher) show the number of dot lines at the direction of lengthwise.

(The relation between data and print result.)

n1 1 byte D8 D7 D6 D5 D4 D3 D2 D1 n3×256+n2 No D1~D8 show the position of dots in each position. In case a point is to be printed in that position, this is to be 1 at binary. In case of space, this is to be 0.

(The available range of parameter specifying)

model n1 n2 n3
24 columns model 1~18 0~255 0~1
40 columns model 1~23 0~255 0~1

Remarks: In case the value is specified out of the above available range or n2 = n3 = 0, bit image mode is canceled and mode is changed to text mode.

This printer prints the data which is not sufficient as a space after Lead -in the data of 4 dots line or after filling the data specified in n1, n2, n3

Remarks 1): In 40 columns, in case n1 = 1 is specifies, 4 dots from lowest columns dots (LSC-DOT) are ignored. This is due to the total number of dot for 1 line is 180.

Remarks 2): Mode is changed to text print mode after printing bit image.

(13) Specifying double wide and double high character command (FS + "W" + 1)

By inputting the code of FS (1CH) + "W" (57H) + (01H), double width and double height is specified.

This command prints the data following after this command as double width and double height.

(14) Cancellation of double wide and double high character command (FS + "W"+0)

By inputting FS (1CH) + "W" (57H) + 0 (00H) code, double width and double height is canceled.

Remarks 1) Although both of standard characters and double wide characters can exist in the same line, in case the total columns go to 24 (40) columns at standard character basis, this printer con-duct buffer full printing automatically.

Remarks 2) In case both of double wide and double high character and double wide character are specified, double width and double height is specified.

Example)

1CW11 2 3 4 5 6 7 8 9CR
1CW0ABC1CW11 2 3 CR
1CW0A1CW11 2 3 4 5 6 7 8 9 0 1 B

1 2 3 4 5 6 7 8 9

ABC 1 2 3

A 1 2 3 4 5 6 7 8 9 1 B Even though the last character is

Even though the last character is specified as double width and double height, since this character is 24 ^th column, this character is printed as an standard character. (In case of 40 columns model, this means 40 ^th column.)
