IMPORTANT NOTES ON TK23 HANDLING

In order to guarantee a long life of the printer, it is necessary to keep some precautions on the TK23 handling. Please read carefully next lines to make a good use of the printer.

SAFETY PRECAUTIONS

Before using the printer, please carefully read point

2- INSTALLATION

. BEWARE not to invert power supply polarity. This may irremediably damage the printer. Use power supply voltage within specified range. Over-voltage may irremediably damage the printer. Voltage under the specified range may cause incorrect operations. Keep TK23 away from water or any other liquid. Do not use in locations subject to high humidity or dust levels. DO NOT put any objects into the printer. It could cause severe damage like shortcircuits, broken thermal head or general printer failure. DO NOT blow the TK23.

•

NEVER modify the TK23.

•

DO NOT try to repair the TK23 by yourself. If some failure is detected contact with your usual dealer technical service.

•

Since the printer contains permanent magnets (in the motor) as well as electromagnets, it should not be used in areas containing excessive dirt, dust and metallic particles.

•

Never print without paper installed or the head away from the platen, because the life of the thermal head may be shortened.

•

Never pull the paper out (forward or backward) with the head down against the platen.

•

Since the head heating elements and the driver IC are very delicate, avoid touching them with any metal objects, such as tweezers or screwdrivers.

•

Since the head area and the motor surface reaches high temperatures right after printing, never touch it with your bare hands; wait about 15 min.

For it to cool.

•

Design the product so that when handled the user can not touch the edge of the printer unit and/or the cut surface of the metal parts used in it, because the edge of the printer unit and the cut surfaces of the metal parts are sharp. Or include any necessary precautions regarding this matter.

•

Never touch the surface of the head heating elements and the driver IC, as dirt may stick to them, affecting the head heating elements or causing damage by static electricity.

•

When printing a black pattern at a high print rate in a low temperature or high humidity environment, the vapour from the paper during printing may cause condensation to form on the printer unit or may soil the paper. If water condenses on the printer unit, keep the thermal head away from water drops as it may corrode the thermal head, and turn printer unit power off unit it dries.

HEAD CLEANING PROCEDURE AND PRECAUTIONS

Do not clean the thermal head immediately after printing because thermal head and its periphery are hot during and after printing. Do not use sandpaper, cutter knives etc. when cleaning. They will damage the heat elements.

a) Open the paper cutter expanding the raised edges slightly as shown in the figure

Figure a. Opening the paper cutter

Lift the head up/down lever until clicking. The thermal head is held in the up position.

Figure b. Head cleaning procedure

Clean the head elements using alcohol (ethanol, methanol, or IPA) and a cotton swab. Wait until the alcohol dries and close the platen block. Fenix recommends cleaning the thermal head periodically (advisable every 3 months) to maintain receipt print quality.

RECOMMENDATION Before connecting any input interface, verify the correct operation of the TK23 printer with self-test feature.

2 – INSTALLATION

2.1- FIXING THE TK23 PRINTER

The TK23 is an industrial printer designed to be fixed in a bigger case or structure, or another kind of appropiate chassis. There are two models for the TK23 printer with 4 different fixing points each.

2.1.1 - TK23 INSTALLATION

• Fix the TK23 to the chassis by screwing, putting 4 metric screws (M4 / L10 mm)

through the holes marked with A

and

B in

fig 2.1 - Fixing the TK23.

• Place all the screws in the same direction, from up to down.

• It is strongly recommended that the fixing holes of your chassis have an oval shape

so as the TK23 can move backward and forward for an easy manipulation.

• The paper-near-end sensor included in TK23 detects when remaining paper is about

17m long (65µm paper thickness).

2.2- TK23 INSTALLATION CONSIDERATIONS

There are some general considerations to take into account when installing the printer with the TK23 printer. A wrong installation can cause many serious problems like paper jam, difficult maintenance of the printer, difficulty in changing the paper roll, etc. Moreover, a correct installation can prevent the printer from being damaged by external agents, such as weather or vandalism.

The basic points that a correct installation must follow are:

• Smooth exit of the ticket. Prevent problems with static electricity due to the nature of

the used materials.

• Allow enough space and accessibility to reach the maintenance procedure points in

case it is needed. These points are:

• Thermal mechanism & Autocutter.

• Paper roll.

• Interface.

• Connectors.

• Led and Push-buttons.

For these reasons, FENIX suggests the following systems as solutions to a correct installation:

2.2.1- EXTERNAL CHUTE SYSTEM

The idea of this system is to internally print and cut the ticket inside the machine, and then make it fall into a receptacle where the user can have external access. Therefore, there must exist some distance between the printer and the front side of the user’s chassis in order to build a useful chute for the ticket, and to be able to open the printer thermal head. Two points must be assured to make this system work right:

• The construction of the receptacle must avoid the user to reach any internal

parts of the machine.

• The way of the ticket from the printer outlet to the receptacle must be smooth,

clean and free of obstacles to allow the ticket to actually fall into it and avoid paper jams or tickets that do not fall. Depending on the construction materials, care must be taken with static electricity; otherwise tickets may get stuck inside the machine and never reach the receptacle.

Next figure shows a scheme of this system:

Make sure this distance allows the opening of the printer thermal head (min: 20mm)

15/81

2.2.2- PAPER GUIDE SYSTEM

When using this system, the printer must be set quite near the front side of the user’s chassis. The paper guide is to avoid external handling of the printer outlet. Two points must be assured to make this system work right:

• Special care in the design of the part which goes from the printer outlet to the

paper guide (Paper jams can a occur due to an inappropriate design). Depending on the construction materials, care must be taken with static electricity; otherwise tickets may get stuck in the paper guide and never reach the receptacle.

• As the printer is placed very near the user’s chassis, some system must be

implemented in order to move the printer when accessing the printing head (i.e. giving the fixing holes of the chassis an oval shape to allow the printer moving forward and backward). Otherwise there will be no access to the printing head.

Next figure shows an scheme of this system:

Fig. 2.4-

Paper guide system.

The distance between the mechanism and the frontal side of the user’s chassis may not allow the opening of the printer thermal head. Take special care about this point when designing your system.

2.3.1- POWER SUPPLY CONNE CTOR

Attach power supply cable to the 3-pin micro connector. Verify power supply voltage before making the connection. The connector is a female 3-pin HOSIDEN type, which have the following pin-out:

Fig.2.6-

Power supply connector as seen from outside the TK23.

Use a 3-pin DC jack KPP-3P model or equivalent.

2.3.1.1 - Optional Power supply connector :

A special version of TK23 (under agreement only), can use for power supply a Male 4pin 0.156" pitch (3,96mm) disconectable Crimp style connector.

User side connector type:

Housing: VHR-4N (JST or compatible)

Contact: SVH-21T-P1.1 (JST or compatible) NOTE: All 4 pins must be connected. Terminals 2 and 3 are VCC (24V DC)

Terminals 1 and 4 are GND

The TK23 requires one power source: VCC (24V DC) for driving the thermal head and motor. This voltage is internally regulated to 5V to control the electronic active parts. The power supply must meet the following conditions:

VCC:

24V DC +/- 2,4V

Example of printhead current consumption (for the 80mm-wide mechanism):

Print head current consumption at a printing ratio of 35%: (Printing ratio is defined as the number of dots/dot lines (576 dots)).

Peak current:

3.05 A (when all 208 dots are powered).

NOTE: Peak current is measured at the minimum resistive value of thermal

head and the maximum operating voltage.

Conditions: VH max: Head connector terminal voltage max. 26.4V

Rmin: Head resistance value min. 1800 Ohm.

The following formula is used to obtain the head drive peak current:

Ipeak = Vmax (volts) x 576 dots x printing ratio / minimum head resistance value (ohms)

FENIX IMVICO

TK23 OPERATION MANUAL

18/81

Mean current:

Approx. 1.4 A

Conditions: - Head terminal voltage = 24V

- Head resistive value Rh = 1800Ohm

- Mean energizing pulse width of 832 µs, synchronizing with 1667µs

motor cycle.

The following formula is used to obtain the head drive current:

Imean = [V(volts)/Rh(Ohms)] x 576dots x printing ratio x [energizing pulse width/cycle]

NOTES:

(1) If the number of dots that are energized at the same time is increased, a higher

current will flow; therefore, the user should use a power supply with a current

capacity adequate for the corresponding print duty. (2) When designing lines and bit images, take the printing ratio and print duty into consideration. (3) Print quality may be poor if the printing ratio or print duty is high. (4) Definitions:

• Printing ratio: the number of printing dots (energizing pulses)/dot line.

• Print duty: the number of printing dots (energizing pulses)/ elements/ paper

feed amount (two steps, including non-printing area)

WARNING: Beware not to invert the polarity of power supply. This may irremediably damage the printer.

IMPORTANT NOTE ABOUT TK23 POWER SUPPLY: The necessary supply of power depends on the content to print on the

ticket. A 150W power supply covers all adverse possibility (printing ratio of 100% black at any temperature). However, if the average print ratio is not over 25%, a 60W power supply can be used. Any way, power supply must meet the peaks current that mechanism requires, which are determined by the following formula:

Ipeak = [24 / 1800] x number of printing dots

NOTE: Transmit data to the printer after turning on the power and initializing the printer.

The TK23 receives data continuously, even while performing printing operation. The TK23 serial input/output signals (RXD, /RTS and TXD) can be RS232C level or TTL

level (see APPENDIX F- HOW TO ORDER).

The TK23 receives and checks serial data according to the transmission baud rate programmed. If the input data is not printed correctly, the transmission conditions between the host

device and the TK23 do not probably match. If this happens, the character “?” is

continuously printed and user must adjust the transmission conditions so that they match.

Serial data output (TXD): output pin, SUB-D9-3

• Data is output according to the programmed transmission conditions.

Serial data input (RXD): input pin, SUB-D9-2

• Data input port

• Data is input from the host device according to the programmed transmission

conditions.

NOTES: (1)

If the host is not provided with all or any of the Centronics Signal lines listed above

(TK23 specific signals are not required), both-way communication can fails.

(2)

For interfacing, is recommended that signal lines use twisted pair cables with the

return sides connected to signal ground level.

(3)

Data transmissions shall not ignore the /ACK or BUSY signals. An attempt to

transmit data with either /ACK or BUSY signal ignored, can cause lost data. (Data transmissions to the printer shall be made after verifying the /ACK signal or while the BUSY signal is at the low level.)

(4)

Interface cables shall have been made with the minimum length required (Max. 2 meters recommended).

3 – BASIC OPERATIONS

3.1- LOADING PAPER

When the printer runs out of paper, there are two ways of loading paper: automatic and manual. Before starting the paper load sequence, please make sure the paper roll has been placed in the right way:

Place the paper roll on the spindle.

2) Place the paper roll in the right direction. The thermal paper has only a side which TK23 can print (thermal side). If the user don’t know which one it is, just scratch the paper: the thermal side will show up the track on.

Place the fixing button to assure the good positioning of the paper roll.

Once in its place, the paper roll must be able to turn around the spindle smoothly, with very low friction.

3.1.1- AUTOMATIC PAPER LOAD

1) Make sure the TK23 is power supplied.

2) Open the printing head and remove paper from inside the mechanism (if there is any).

3) Make sure that the printing head is closed.

4) Make sure the paper end is cut in a straight way.

Fig.3.1-

Automatic paper load.

Pass the paper end below the paper guide as shown in fig. 3.0 and fig 3.1

and

enter the paper in the mechanism inlet.

6) Push the paper in until the TK23 detects it and starts the auto-load sequence.

7) Wait until the auto-load sequence extracts the paper from the printer outlet.

NOTE:

In the automatic paper load, the printer motor runs at low speed, because the printer

needs the maximum motor torque. Running at low speed, the motor is noisier, but it is not a wrong performing.

3.4- SPECIAL MODES

Apart from the normal printing mode, where all the data received by the printer is printed according to the adjustments or conditions set by the commands also received and processed, the TK23 allows three

SPECIAL MODES

which must be set at the moment

of turning on the printer or via commands.

3.4.1- SELF-TEST MODE

The printer has a self-test function that checks the following:

• Firmware version.

• Printer mechanism which is connected to the printer interface.

• Interface operating.

• Printing speed.

• Print density.

• Selected font.

• Character scale.

• Character spacing.

• Line Spacing.

• Status of the Black Mark sensor.

• Status of the CR command function (See point 4.CONTROL COMMANDS).

Starting the self-test mode:

To start the self-test on a paper roll, turn off the printer, and hold down the PFEED button then turn on the printer. Then the current printer status is printed.

After printing the current printer status, if the PFEED button is still hold down, the TK23 will print the scaling text pattern printing. While printing this sample text, some features of the TK23 can be checked:

• Control circuit functions.

• Status of the printer mechanism which is installed.

• Print quality (at current print density).

• Interface type and its operating condition.

• Control software version.

• Idea of its printing speed.

3.4.2- PROGRAMMING MODE

The TK23 has a PROGRAMMING MODE in order to set up some parameters of the printer, without sending any command. In this mode, the printer makes some questions to the user. These questions must be answered by pressing one of the two push buttons. PFEED button means “YES” and “PROG” button means “NO”.

Fig. 3.5-

Programming buttons.

NOTE - You can use the in-board push buttons: SW1 is PFEED and SW2 is PROG

Starting the programming mode:

To start the programming mode, turn off the printer, and hold down the PROG button then turn on the printer. Then the printer asks for the configurable parameters.

These are the configurable parameters during PROGRAMMING MODE:

• Mechanism: LTP2242 series at 60mm, LTP2342 series at 80mm or

LTP2442 series at 112mm (total cutter or partial cutter).

• Baudrate: 4800, 9600, 19200 or 38400 baud.

• Parity for serial transmission: ODD, EVEN, NO PARITY.

• Head Activation: 1 strobe (fixed mode) or 2 strobes (dinamic mode).

• Print density: Light (-50%), Normal or Dark (+50%).

• Black Mark: Enable / Disable marked paper.

• Carry Return: Enable / Disable CR command.

3.4.3- HEXADECIMAL DUMP MODE

The hexadecimal dump prints the data transmitted from the host computer as hexadecimal numbers and their corresponding ASCII characters.

In this mode, no commands are processed. All the received data is printed as it is in Hexadecimal mode. This is very useful for the user can debug the software implementation during the initial period of his application. He can check whether the communication is correct and the commands are well defined. If a set of commands and data does not act as it was expected, the error can be easily detected using this mode, for the user can compare what he is supposedly sending to the printer and what the printer is actually receiving.

Starting the hexadecimal dump: To start the hexadecimal dumping, turn off the printer, and hold down the PFEED button and the PROG button then turn on the printer. Then the printer first prints “Hexadecimal Dump” on the paper roll and prints the received print data in hexadecimal numbers and in its corresponding ASCII characters.

NOTES:

(1) If no characters correspond to the data received, the printer prints “.” (2) During the hexadecimal dump, no commands are processed.

Ending the hexadecimal dump: You can end the hexadecimal dump by turning the power off.

Next figure shows an example of the HEXADECIMAL DUMP MODE:

3.5- ERROR PROCESSING

The TK23 can detect several errors. These errors are indicated in different ways depending on their relevancy and on the communications interface used (serial or parallel). There are two ways of indicating these errors:

•

SERIAL PORT:

When an error occurs, the DTR signal goes to active level (logical “HIGH” level). If the user detects that this signal is “high”, that means that an error has occurred. The TK23 can send the STATUS BYTES by the serial port, to communicate some of these errors (command

DEL EOT

), in

RS232 protocol.

•

PARALLEL PORT:

When a No Paper / Head-Up error occurs(see 3.5.1), it is indicated in the PE and /ERR signals. If a generic error ocurrs, it is indicated in the /ERR signal. Paper-Near-End sensor can be signaled in the PE signal by using Control Commands (see 3.5.2).

NOTE:

(1) For more information on how each error is indicated see points 3.5.1 to

3.5.8, here every error is explained in detail.

Name Description

NO PAPER There is no paper in the printer inlet HEAD-UP The thermal head is open PAPER-NEAR-END The paper roll is near its end HEAD TEMPERATURE The thermal head temperature is above 75ºC CUTTER The autocutter can not cut VOLTAGE

The thermal head voltage is out of range (Vp = 24V ± 10%)

HARDWARE There is an error in the control board interface OPTICAL MARK The optical mark is not detected NO ERROR There is no error

Table 3.1-

Errors explanation.

3.5.1- NO PAPER / HEAD-UP ERROR

Although these two errors have different causes, they are indicated in the same way because the action to recover from these errors is actually the same. This error is quite significant, so when it arises the motor stops and no printing is allowed.

• ERROR ORIGIN: There is no paper in the printer inlet or the thermal head is open.

• LEDS INDICATION: The PE led turns ON.

NOTE:

(1)

This error is indicated in the parallel port depending on the conditions set by

the

”ESC c 3”

command (See point 4. CONTROL COMMANDS).

• RECOVERY: To recover from this error, user must do a paper load (See point 3.1- LOADING PAPER), or turn down the head lever.

FENIX IMVICO

TK23 OPERATION MANUAL

35/81

3.5.2- PAPER-NEAR-END ERROR

This error is not as significant as the “NO PAPER/ HEAD-UP” error. So, the user must decide what to do when this error comes. Depending on the settings of command

“ESC

c 4”

this error stops the printing or not (See point 4. CONTROL COMMANDS).

If this error is set to stop the printing, it will be detected as any other error. If this error is not set to stop the printing, user must detect it by polling the status bytes.

• ERROR ORIGIN: The paper-near-end sensor does not detect the paper roll.

NOTE:

This error is indicated in the parallel port depending on the conditions set by the

”ESC c 3”

command (See point 4. CONTROL COMMANDS).

• RECOVERY: To recover from this error, user must change the paper roll.

3.5.3- THERMAL HEAD TEMPERATURE ERROR

Due to very continuous use of the printer, or due to environmental conditions, the temperature in the thermal head may reach levels, which can damage the printer itself. When this situation occurs, an error must be indicated in order to protect the printer from abrasion. This error recovers automatically and the printer returns to normal status when the thermal head temperature drops to an acceptable level (below 70 ºC).

• ERROR ORIGIN: The thermal head temperature raises over 75 ºC.

• RECOVERY: The printer automatically recovers from this error when the thermal

head temperature drops below 75 ºC.

3.5.4- AUTOCUTTER ERROR

In some cases, after cutting a ticket, the cutter blade can be out of its home position. In other cases, an object may be obstructing the cutter blade, making it impossible to cut the ticket. After cutting a ticket, the printer checks the right position of the cutter blade, and if it has not returned to its home position, the printer indicates an error.

• ERROR ORIGIN: For some mechanical reason, the cutter blade can not return to its

home position after trying to cut.

• RECOVERY:

Not attempt turn up the head lever, because this can damage the

cutter blade.

The printer tries to automatically recover from this error at printer initialization (turn the printer OFF / ON). Remove the external paper or objects, and try recovering the cutter blade turning ON/OFF some times. If the cutter blade had been recovered, turn up the head lever and remove the internal paper or objects. If the cutter blade is still blocked, cutter unit must be replaced. See also

APPENDIX C

for manual recovering.

FENIX IMVICO

TK23 OPERATION MANUAL

36/81

3.5.5- THERMAL HEAD VOLTAGE (Vp) ERROR

The thermal head needs a stable voltage to produce a correct printing. This voltage is in the range of 21,6V to 26,4V. When the thermal head voltage (Vp) goes out of this range, correct printing can not be assured, so an error occurs.

• ERROR ORIGIN: The thermal head voltage (Vp) is out of range (24V ± 10%).

• RECOVERY: This is a Non-recoverable error. The only way to return the printer to a

normal status is to turn it OFF / ON and make sure that this time, the thermal head voltage (Vp) is in the specified range.

When this error occurs, some parts of the printer may be damaged. If this happens, the printer will be unable to recover itself and some of its components are likely to be replaced. Check the TK23 power supply.

3.5.6- HARDWARE ERROR

At initialisation, the printer internally checks its hardware devices. If they do not function properly, an error occurs.

• ERROR ORIGIN: Some of the printer hardware devices do not function properly.

• RECOVERY: This is a Non-recoverable error. One of the control board components

may be damaged and it is quite sure that the control board needs to be changed or repaired.

3.5.7- OPTICAL MARK ERROR

The printer can use marked paper. The use of the optical mark must be enabled via

hardware on printer start-up (See point 3.4.2- PROGRAMMING MODE). An error can

occur if:

• The paper does not have optical mark.

• The optical mark is not in the right position.

• The optical mark does not have the right size or intensity.

NOTE:

See point 3.6- OPTICAL MARK for details on using marked paper.

• ERROR ORIGIN: The optical mark sensor does not detect the optical mark.

• RECOVERY: This is a Non-recoverable error. User must turn OFF the printer, and

check the paper and optical mark characteristics.

3.6- OPTICAL MARK

The TK23 printer has the capability of using the No-Paper mechanism sensor as an optical mark sensor to work with paper, which is pre-printed with an optical mark. To make use of this feature, the optical mark sensor must be enabled via hardware (See

point 3.4.2- PROGRAMMING MODE).

The optical mark must be placed in the back of the paper, and in its right side as seen in

Fig. 3.11.-

Optical mark characteristics

The optical mark must satisfy the dimensions shown in Fig. 3.11.-

Optical mark

characteristics

The optical mark is detected at the position, which the top edge of the optical mark comes into approximately 2mm from the middle of the optical mark sensor. After detecting the optical mark, it is not detected for approximately 2cm.

The reflecting rate of the optical mark must be 10% or less, and the reflecting rate of the white must be 75% or more. The reflecting rate means the value, which is measured with Macbeth density meter (PCMII) D filter.

By factory default setting, the cutting position is corrected 25mm forward and the printing position is corrected 12,5mm backward:

with this adjustments paper begins exactly at the position of the paper optical mark (where the optical mark sensor makes the detection). If you are using partial cut (see page 49), correction backward are not recommended.

The print starting position and the cutting position can be changed with the GS ( F command (See point 4- CONTROL COMMANDS)

3.6.1- EXAMPLE ON USING THE OPTICAL MARK

Some very concrete points must be observed when using the optical mark.

There are three commands for handling marked paper (See point 4- CONTROL COMMANDS for more details)

GS ( F

! Set adjustment values. This command allows setting the distances between the optical mark and the cutting position and printing position. These distances can be positive or negative starting from the optical mark.

GS FF

! Feed marked paper until printing position. This commands feeds paper until finding an optical mark. Then it moves the ticket backward or forward until placing it at the printing position.

GS V m n

!Cut paper. This command feeds paper until optical mark, then moves the

ticket to its cutting position and cuts, then it moves the ticket to the printing position.

Other considerations:

•

Paper can only be fed backward by using these previous commands. Feed backward is only recommended if Full Cut Autocutter is selected (see pag. 49 CONTROL COMMANDS ESC i / ESC m for more explanation).

•

Is highly recommended that the total amount that paper can be backward fed is less than 120 steps (15mm).

•

Pressing the PFEED button when the Optical Mark is enabled is the same as sending the GS V m n command.

Recommendations for the use of marked paper:

The optimum use of the marked paper follows this logical sequence: Place the current ticket at its printing position (PP): Print current ticket Use optical mark in current ticket to place current ticket at its cutting position (CP) Cut current ticket Place next ticket at its printing position (PP).

Marked paper normally uses tickets of the same length. Therefore the printing position (PP) and cutting position (CP) are the same for every ticket. Consequently, the optical mark handling sequence is the same for every ticket.

By default the distances for CP and PP are:

Printing position: 10mm after optical mark. Cutting position: 25mm after optical mark.

2. When using Code128 in this printer, take the following points into account for data transmission:

! The top of the bar code data string must be the code set selection character (CODE A, CODE B or CODE C), which selects the first code set. ! Special characters are defined by combining two characters “{“ and one character. The ASCII character “{“ is defined by transmitting “{“ twice consecutively.

4. If the combination of “{“ and the following character does not apply any special character, the printer stop command processing and processes the following data as normal data.

5. If the printer receives characters that cannot be used in the special code set, the printer stop command processing and processes the following data as normal data.

6. The printer does not print HRI characters that correspond to the shift characters or code set selection characters.

7. HRI character for the function character is space.

8. HRI characters for the control character (<00>H to <1F>H and <7F>H) are space.

<Others> Be sure to keep spaces on both right and left sides of a bar code. (Spaces

are different depending on the types of the bar code.)

APPENDIX C – RECOVERY FROM AUTOCUTTER ERROR

____________________________________________________________________

• If a foreign object, such as a push pin or paper clip, drops in the autocutter and

causes the autocutter to lock up, the printer enters an error state and begins the recovery operation automatically.

If the problem is not serious, the autocutter returns to its normal position without any intervention by the user.

If the autocutter does not return to its normal position by itself, turn the printer off. Insert a Phillips screwdriver through the slot as shown in

figure C.1

and into the

screw in the worm gear of the motor axis. Then, turn the screw until blade retreats.

• If you cannot rotate the motor gear, rotate it in the reverse direction to loosen it; then

press the paper feed button. Open the platen unit

(see pag. 7

figure a)

, remove

the jammed paper, and reinstall the paper roll. Then close the platen unit.

APPENDIX H – CODE128 BAR CODE

____________________________________________________________________

In Code128 bar code system, it is possible to represent 128 ASCII characters and 2digit numerals using one bar code character that is defined by combining one the 103 bar code characters and 3 code sets. Each code set is used for representing the following characters:

G.1 Description of the CODE128 Bar Code

• Code set A: ASCII characters 00H to 5FH

• Code set B: ASCII characters 20H to 7FH

• Code set C: 2-digit numeral characters using one character (100 numerals from 00

to 99)

The following special characters are also available in Code128:

SHIFT characters

In code set A, the character just after SHIFT is processed as a character for code set B. In code set B, the character just after SHIFT is processed as the character for code set A. SHIFT character cannot be used in code set C.

Code set selection character (CODE A, CODE B or CODE C)

This character switches the following code set to code set A, B or C.

Function character (FNC1, FNC2, FNC3 or FNC4)

The usage of function characters depends on the application software. In code set C, only FNC1 is available.
