NOTE
• Set the print paper in the correct direction.
• When closing the front panel, be sure not to catch paper. Otherwise, paper jam, etc. may
occur.
• Do not start printing without print paper properly held in the paper holder; otherwise, paper
jam or the like may occur.
• While replacing the paper, do not send data from the host.
• Do not pull the paper in reverse direction of paper feed. This may cause abnormality of print
head.
• In case the paper is set at as skew angle, paper jam may occur. If paper jam occurs, turn off the
power switch and pull out the jammed paper slowly straightforward in the paper feed direction.
• Note that if “Auto clear after paper setting”is set and data is present in the print buffer, print
operation starts automatically after print paper is set.
• Do not use roll paper of φ50 mm or more. Otherwise, paper jam or the like may occur.
NOTES ON PAPER
Shape:
Use the roll paper with the beginning of winding (innermost end of the paper roll)
treated as follows:
(1) No fold and well aligned to inside diameter.
(2) No flap
(3) Not pasted to the paper core (if any).
(4) No colored part facing PNE sensor (Otherwise, variations in PNE sensor
detection may occur.)
Recommended paper:
One-ply paper..... 45 to 55kg / 1,000 sheets / 1091 x 788 mm
Paper roll diameter
(1) With core
Use paper core of f12 mm inner diameter and f18 mm outer diameter.
Using paper core of greater than f18 mm or cone type may have effect on
the PNE sensor.
(2) Without core
Start winding for printing at the position of f12 mm or more. The PNE
sensor starts detection of PNE (Paper Near End) around f20 mm. If you use
a roll paper without core, keep the paper remainder in mind.
If the start of winding is f12 mm or more, print paper may flip flop in the
printer and may affect PNE sensor detection.

Memory switch setting can be changed by a command or by manual operation.
a) Change by command
Memory switch can be changed by a command. For details, refer to “8.
Print Control Function”.
When the printer receives the command, it outputs a BUSY signal and enters
memory setting mode. After writing into memory switch, software resetting
is carried out and the receive buffer/print buffer are cleared causing each
set value to return to the initial value and then the contents of the memory
switch(es) are reloaded.
Commands are set one by one. Use care when changing two or more set
values.
— 21 —
b) Change by manual operation
Set the DIP switch (SW1) No. 4 at the back of the printer to ON. Turn the
printer power on while pressing and holding the FEED switch.
The printer prints the information on the current memory switch setting
and then enters the Change Setting mode.
In this case, the PAPER lamp and the POWER lamp blink alternatively at 1second intervals and the BUSY signal is outputted.
Using the FEED switch, choose one of the options for each setting item.
Changing setting item
A total of 15 setting items are available.
The printer prints the contents of setting items and current set values on
print paper.
Pressing the FEED switch short causes the setting item to move.
When all the setting items are changed, the re-setting state or writing
(registering) to memory switch state is reached.
To change the value of setting item, press and hold the FEED switch for
more than 1 second. Current set value is printed with a mark “?”.
Changing options
When item to be selected in the setting items is specified, current option is
printer with a mark “?”.
When selecting an option, press the FEED switch short. Specified options
are printed one by one. When the last option is reached, selection is returned
to the first.
To decide the selection, press and hold the FEED switch for more than 1
second.

(1) Paper-near-end (PNE)
When the print paper becomes scarce, the printer detects paper-near-end.
This error occurs when the PNE sensor detects paper-near-end consecutively for
approx. 2 seconds. When the printer detects enough paper for more than 1 second,
the paper-near-end is cleared automatically. The indication and signal status
varies in accordance with the setting status of memory switches 5, 8 and 9.
(2) Paper-end (PE)
If the print paper runs out of paper, the printer detects paper-end. If the printer
detects PE during printing, it stops printing. PE is cleared when new paper is set.
The PAPER lamp lights (blinks) and issues BUSY and PE signals to the host.
(3) Mechanism error (Mechanism alarm)
This alarm is issued when the printer mechanism is locked by paper jam or the
like during printing or paper feeding.
The printer outputs the BUSY and FAULT signals to the host. The PAPER lamp
blinks depending in accordance with the status of memory switch setting.
After removing the error state, press the FEED switch to restore.
If the error state cannot be cleared, turn the printer power off and verify the error
status.
(4) Memory error (RAM error)
This error is issued when error occurs in the memory built in the printer at the
time of printer power on.
The PAPER lamp blinks and outputs BUSY and FAULT to the host.
Turn the printer power off and then turn the printer on. If error still occurs with
the printer power on, this is an unrecoverable error. Contact your nearest CITIZEN
SYSTEMS dealer.
PNE, PE, Other errors
(5) Memory switch error
This error is developed when any abnormality is detected in the setting of memory
switch when the printer is powered on. This error is recovered by resetting the
memory setting and turning the printer power on again.
If the error cannot be recovered even by resetting, turn the printer power off and
contact your nearest CITIZEN SYSTEMS dealer.
(6) Voltage error
This error occurs when the printer detects abnormal supply voltage in mechanism
driving system when the printer power is turned on or during printer operation.
The PAPER lamp blinks and outputs BUSY and FAULT to the host. This is an
unrecoverable error. Turn off the printer immediately.
This error occurs when the fuse for mechanism driving is blown.
For details of the lamp state and interface signal state at the occurrence of error, refer
to the next page.
For serial interface model, read the BUSY signal as DTR signal.

4.12 Special Functions
This printer allows following printing and setting by using “Back switch” located on
the back of the printer.
(1) In case of normal printing operation
When the printer is ready for printing in normal operation, press and hold this
switch for more than 3 seconds (PAPER lamp lights) and then release it. The
printer prints the detailed status of memory switches currently set.
When pressing and holding this switch for more than 6 seconds and then releasing
it (PAPER lamp goes off), the printer starts self-printing.
(2) In case of memory switch setting
When the printer is ready for selecting items in the state of transferring to memory
switch setting mode, pressing and holding this switch for approx. 3 seconds or
more and then releasing it results in transfer to the last item selection state (state
of re-setting or selecting memory switch writing).
If this switch is pressed for approx. 6 seconds or more and then released, the
memory switch is restored to the initial state. As the initial state is only set in the
setting mode, writing to memory switch is necessary. If the FEED switch is kept
pressed when this switch is released, the printer is initialized to domestic setting.
If the FEED switch is not pressed, the printer is initialized to overseas setting.

6.5 Error Detection
This printer detects the following communication errors in the data communication
of serial interface. When any error occurs, the printer converts (or may ignore in
some case) the data at the occurrence of the error to the characters set by the memory
switch and then prints the characters.
• Parity error
Parity error occurs when parity check is specified and parity is not observed in
the even and odd parity checks.
• Framing error
When space state detected on detection of stop bit.
• Overrun error
This error occurs when next data is transferred to receiving buffer though input
buffer is full of data.
RECEIVING CONTROL AND BUFFERING
This equipment controls, on receipt of print data, receiving (DTR Control) in one-word
unit. If the host disregards DTR and carries out data transmission at this time, overrun of receiving data may be resulted. This state should be avoided on the host’s
responsibility. (The data discharging type host cannot follow this.)

8.2 Control Code Details
(1) Command for Line Feed After Printing (CR/LF)
By entering CR (0DH)/LF (0AH) codes, data in the print buffer is printed followed
by a line feed. Without data in the print buffer, only a line feed is performed.
This command is ignored just after buffer full in case of 920 emulation.
CR and LF are valid in the following conditions.
CBM-920 Emulation
Serial LF only CR and LF
Parallel LF only CR and LF
iDP3110 Emulation
Serial CR only LF only
Parallel LF only CR only
SW1 Switch No.1
OFF ON
SW2 Switch No.2
OFF ON
(2) Specify/Clear double-width character (SI, SO, US, RS, and DC4) command
SI/SO codes function in the same manner as US/RS as long as 8-bit data are
assigned (serial communication data bit length), which, however, are divided,
under 7-bit assignment, into SI (20H~7FH characters) print assignment and SO
(A0H~FFH characters) print assignment functions.
1. Standard letter assignment (SO/RS) command:
With SI (0FH)/US (1FH) codes input, lateral enlargement is cancelled and
the data following are printed in standard letters. This command can cancel
only lateral enlargement, which dose not apply to ×4 enlargement.
2. Laterally enlarged letter assignment (SO/RS) command:
With SO (0EH)/RS (1EH) codes input in any columns, the data following are
printed in prints enlarged double in width.
Although standard and enlarged letters can be mixed within one line,
automatic (buffer-full) printing takes place when the number of columns
reaches 24 (or 40) counted in standard letters. With 920 emulation, laterally
enlarged letter assignment is cleared by printing after line feed, followed
by SI, US, and DC1. With 3110 emulation, it is cleared by printing after line
feed by LF and CR, followed by SI, US, and DC4.

(3) Data Cancel (CAN) Command
With CAN (18H) code input, print data held within the line before input of the
CAN code are all cancelled.
[Results of Printing][Example of print data]
CAN ABC CRSO 123456
* As data “123456” are cancelled without the command “SO” cancelled, “ABC”
is printed in lateral enlargement.
(4) Inverted Letter Assignment (DC2) Command
When data are input with DC2 (12H) attached at the beginning of a line (invalid
when attached to any other place), data following are all printed in inverted letters.
To cancel this, input either DC2 again or DC1 (initial setting.)
(5) Initial Setting (DC1) Command
With DC1 (11H) input, various conditions set after power supply are cancelled
and the state as at supply of power is restored.
Content of the input buffer, however, is held unchanged.
(6) Continuous Paper Feed Assignment (ESC + “B”) Command
With ESC (1BH) +“B” (42H) + n code input, continuous paper feed at n-dot line is
executed.
However, n allows continuous paper feed to be executed at even-numbered dot
line in the range of 4 ≤ n ≤ 255. If n is specified otherwise, this command is
cancelled.
When this command is entered, print data, if any, in the input buffer is printed.
Print line (10-dot line) is included in the amount of line feed “n”; therefore, 4 ≤ n
≤ 9 provides a line space of “0”.

(9) Sentence Registration (ESC + “/”) Command
With input of ESC (1BH) + “/” (2FH) + n + ‘registered’ + CR (0DH) / LF (0AH) code,
24 (40)-bytes data following n are registered. Set a numeral of 1~8 to n.
With any other numeral having been set, data following is regarded as print data,
where no registration takes place and printing conducted.
Data cannot exceed one line and must be ended with CR (0DH) or LF (0AH).
To r egister a statement exceeding one line, the statement up to 24 (40) bytes is
registered and the data following is printed out as print data.
The ESC command cannot be registered.
The registered data is cleared when the printer is turned off.
(10) Registered Sentence Printing (ESC + “!” ) Command
With ESC (1BH) + “!” (21H) + n code input, the statement already registered in
the numeral assigned to n is printed.
Assign, to n, a numeral of 1 to 8. With any other numeral having been set, no
execution takes place.
Note 1: As much as 24 (40) bytes of data can be registered. In case that 24 (40)
columns are exceeded on printing (because of enlarged or ×4 letters
having been assigned, etc.), printing is conducted up to 24 (40)th column
and the columns overflowed are printed in the next line. Be sure to
make registration in consideration of printing results.
Note 2: When double height and width character printing or inverted character
printing is executed in registered sentence printing, this setting is active
even after returning to normal printing unless that setting is cancelled.

(11) Registered Letter Valid/Invalid (ESC + “%”) Command
Whether a registered pattern is valid or invalid is set with ESC (1BH) + ”%” (25H)
+ n code being input.
n = 1 (01H): Registered pattern to be made valid.
(Addresses for which no registration change has been conducted are taken as
inside fixed characters.)
n = 0 (00H): Registered pattern to be made invalid.
(Taken as inside fixed character sets.)
With CBM-920 emulation 40-digit version, to use the registered characters, it is
necessary to set the registered characters to be valid using this command. With
iDP3110 emulation and CBM-920 emulation 24-digit version, the registered
characters are valid at the registration of the user-defined characters without
setting the registered characters to be valid.
To reset to the state where inside fixed characters are usable while registered
characters are valid, it is necessary to disable the registered characters. Command
for setting to invalid operates regardless of the emulation or number of digits.
Registered Characters Enable/Disable Command Set to Valid Set to Invalid

CBM-920 Emulation (24 digits) × O
iDP3110 Emulation (40 digits) × O
iDP3110 Emulation (24 digits) × O
O: Operation enabled by the Valid/Invalid command of registered characters.
×: As the registered characters are valid by the Register User-defined Character
command, it is not necessary to set the registered characters to be valid.
(12) Character Registration (ESC + “&”) Command
1. For 24-column model (ESC + “&” + A1 + A2)
Individual patterns can be registered by entering the code ESC (1BH) + ”&”
(26H) + A1 + A2, then entering the pattern data.
A maximum of 224 characters can be registered, and any address in the
range of 20H to FFH can be used for the registration. However, if a new
pattern is registered in an address already in use, existing data is cleared
and the newly entered data becomes valid.
[Address setting]
Specified address is matched to the character code and can be accessed
likewise to the stored fixed character record. If a fixed character is defined
in the specified address, the fixed character becomes invalid.
A1 signifies the starting address for the registrations, A2 is the ending
address. When A1<A2 or (A2-A1)>7 is specified, no registration occurs and
data following is treated as print data.
— 41 —
[Method of data transmission]
1) Single character registration
Select the address to be defined (character code) from among 20H to
FFH and designate is as A1. When registering a single character,
starting and ending addresses match each other. That is, A1=A2.
<Example>
A 6 × 6 dot matrix full dot pattern is to be registered in address 41H
(code for the fixed character “A”. (Numerals are hexadecimal.)
ESC + “&” + A1 + A2 + “Pattern data (6 bytes)”
1B 36 41 41 FF FF FF FF FF FF
In the successive controls, a 6 × 8 dot matrix full dot is output whenever the
character code 41H is specified. (Character “A” cannot be accessed.)
2) Multiple character registration
By repeating the single character registration, a maximum of 8
characters can be registered. When defining multiple characters in a
successive address (character code), register pattern data for a
maximum of 8 characters by designation A1 as the starting address
and A2 as the ending address.
((A1-A2)+1)x6 bytes are required for pattern data.
Note: A1 < A2, A2 – A1 ≤ 7
[Pattern data configuration]
Pattern data to be registered must consist of 6 bytes per character. That is,
pattern data configured by a 6 × 8 dot matrix is broken up into 6 vertically
positioned units each of which is represented by 1 byte of data. All together,
6 bytes of data are transmitted.
<Example> When transmitting the following data:
321 654
0
1
2
3
4
5
6
7
1 2 3 4 5 6
[Printing of registered letters]
To print registered character, in the same manner as printing other fixed
characters, use the commands (CR, LF, ESC + B + n).
— 42 —
2. For 40-column model
In CBM-920 emulation (ESC + “&” + C1 + A1 + A2)
In iDP3110 emulation (ESC + “&” + A1 + A2)
With ESC (1BH) + ”&” (26H) + {C1} + A1 + A2 code and the pattern data
following input, a pattern is registered. Only CBM-920 emulation is specified
for { }. Up to 224 characters can be registered into addresses from 20H to
FFH. When the same pattern data is registered in the same address, data
registered before is cleared and the new data becomes valid.
[Recognition of use of upper most bit]
For recognition of use or non-use of the uppermost bit by a character to be
registered, set data to Parameter C1.
C1=0 (00H): Uppermost bit not used.
Other than C1=0: Uppermost bit used.
If 0 is set to this parameter regardless of whether most significant bit is
specified, character as imaged cannot be registered.
[Setting of addresses]
A1 : Registration starting address (20H~FFH)
A2 : Registration ending address (20H~FFH)
[Pattern data configuration]
Pattern data to be registered must consist of 9 bytes per character. That is,
pattern data configured by 9 × 8 dot matrix is broken up into 9 vertically
each of which is represented by 1 byte of data. All together, 9 bytes of data
are transmitted.
In case of iDP3110 emulation, blank data is automatically assigned to the
8th and 9th lines and pattern data consisting of 7 bytes is transferred.
<Example> When transmitting the following pattern data:

As the 40-column model is of half-dot printing system, continuous dots
cannot be arranged in the printing direction (lateral direction). Therefore,
even if any pattern is specified at point “*” at the right of point “●” above,
it cannot be registered as a pattern.
In case of CBM-920 emulation, when data is printed with print data arranged
on the 9th line, some effect may occur in the print pattern of the next print
character.
In case of CBM-920 emulation, registering two-character data and configuring
one double-width character is available.

(13) Bit Image Printing (ESC +“K”) Command
With ESC (1BH) + K (4BH) + n1 + n2 + n3 code being input, conversion from Text
mode into Bit Image mode takes place. The n1/n2/n3 assigns amount of
transmission of bit image data which follows these. Where, n1 represents the
no. of bytes in lateral direction and n2 (lowermost)/n3 (uppermost) represent the
no. of dot lines in vertical direction.
[Relations between data and print-out]

D1~D8 indicate dot location in each position.
To place a dot in a particular position,
put 1 in binary and 0 for a space.
[Parameter assignable range]
Model n1 n2 n3

40 columns 1~23 0~255 0~1
In case that assignment has been made out of the assignable range or n2 = n3 =
0 has been assigned, Bit Image mode is cancelled and Text mode starts.
On completion of receiving 4-dot-line data or on completion of receiving n1/n2/
n3 assigned data, this printer starts printing with insufficient data treated as
spaces.
Note 1: With n1 = 23 having been assigned in 40-column model, 4 dots from the
lowermost column (LSC-DOT) are made invalid. This is because the
printing position in one line equals 180 dots.
Note 2: On termination of bit image printing, Text mode is reinstated.
— 45 —
(14) x4 Enlarged Letter Assignment / Cancel (FS + “W”) Command
Specifies/clears double-height, double-width character by the entry of FS (1CH) +
“W” (57H) + n code. If double-height, double-width character is specified,
character data following this code is printed enlarged by 2 times both vertically
and horizontally.
n= (00H) : Clears double-height, double-width character.
n= (01H) : Specifies double-height, double-width character.
Note 1: Although standard and laterally enlarged letters can coexist in one line,
automatic (buffer-full) printing takes place on reaching to 24th (40th)
column counted in standard characters.
Note 2: With x4 enlargement and double-width having been assigned, x4
enlargement has priority.

(15) Set Line Spacing (ESC + “A”) Command
Sets a line space of “n” dot line by the entry of ESC (1BH) + “A” (41H) + n code.
Initial setting is 2-dot line space.
Here, n is an even number in the range of 0 £ n £ 255.
Note: When an odd number is set to n, a line space of n-1 dots is specified.
When n=0 or 1 is specified, continuous printing is permitted.
(16) Power Down Function (DC2, DC3) Only when 3110 emulation is selected
1.CBM-920 emulation
When the DC3 (13H) code is entered, the POWER lamp on the back of the
printer goes off.
In other case, normal operating condition is maintained.
If paper-end, mechanism error, or the like occurs, the POWER lamp lights/
blinks correspondingly and returns to normal indication.
The DC2 (12H) code is assigned to the command with another meaning.
— 46 —
2.iDP3110 emulation
In order to reduce power consumption when printer is not in operation, two
power down modes triggered by the codes DC2 (12H) and DC3 (13H) are
available with this printer.
When the printer receives DC2 (12H) or DC3 (13H), it enters the power down
mode after all data previously received is printed out.
To exit the power down mode, re-enter the printer power or apply the “LOW”
signal to the RESET terminal for more than 4 ms.
(a) DC2 (12H)
The printer enters the power down mode when DC3 (13H) code is
entered. In this mode, the oscillator does not stop oscillation.
(b) DC3 (13H)
The printer enters the power down mode when DC2 (12H) code is
entered. Operation of the oscillator is terminated, reducing the power
consumption to less than that of the DC2 power down mode.
(17) Change Memory Switch (ESC + “)“) Command
By the entry of the ESC(1BH)+ “)”(29H)+55H+n1+n2+AAH code, contents of
memory switch shown in the table below can be changed.
When receiving this code, the printer enters the BUSY state and writes specified
data (value) to the memory switch.
In this case, the printer performs reset operation. Here, the input buffer/print
buffer is cleared, all set values are restored to the initial value, and the contents
of memory switch are read again.
This command cannot be executed consecutively. When two or more memory
settings are changed, set the value one by one.
NOTE
• If the parameter value is other than specified, writing to memory switch is not carried out.
• If the first byte and the fourth byte of parameter is other than specified code, writing to memory
switch is not carried out.
• In case of serial interface, communication bit length must be set to 8 bits. When set to other
than 8 bits, the communication bit length must be set to 8 bits by manual setting or the like.
* For manual setting, refer to “4.9 Setting Memory Switch”.
