IMPORTANT NOTES IN SM2000 THERMAL PRINTER MANAGEMENT

In order to preserve the life of the printer, it is necessary to keep in mind some precautions in thehandling of the SM2000 printer. Please read carefully the following points in order to make a good use ofthe printer.

SECURITY PRECAUTONS

Before using the printer, read carefully section 2-INSTALLATION. NEVERconnect the external power supply with the wrong polarity. This could permanently damage

the printer. Turn off the printer immediately if it produces smoke, a strange smell or an unusual noise. Keeping

on using the printer could cause fire. Unplug the equipment immediately and contact your officialdistributor.

NEVER connect cables with different connectors from the ones mentioned in this manual. Makingdifferent connections (for example, connecting a telephone line in the coins drawer connector) couldpermanently damage the printer.

Use a power supply voltage whose output voltage is within the specifications range stated in thismanual. Over voltage can permanently damage the printer. Under voltage can cause malfunctions.

NEVERwet SM2000 thermal printer with water or any other liquid. If any liquid is spilled inside of theequipment, unplug the power cable immediately and then contact your technical service.

Make sure the printer is on a steady, horizontal, securely fixed surface. If the printer fell down, it couldbreak or damage.

NEVER use the printer in high humidity or dirty places. NEVERplace heavy objects on top of the printer and never lean on it. NEVERput any object inside of the printer, as it could cause hardware damage on it, such as short-

circuit, print head breaking or general failure of the printer. NEVERshock the SM2000 printer. NEVERdisassemble or modify the SM2000 printer. NEVERtry to repair the SM2000 printer. Please contact your official distributor in case of failure. As the printer contains electromagnets (inside of the motor), it should not be used in excessively dirty

environments or places with dust or metal particles. NEVERprint without paper loaded or without the cover closed, as the thermal print head life can behighly shortened.

NEVERpull the paper out when the cover is closed. Use the paper advance button instead. Avoid touching with metal objects, such as screwdrivers or tweezers, the print head thermal elements

as well as the electronic printed circuit. They are delicate parts. Never touch with your hands the areas around the print head and the motor surface as they become

very hot during and just after printing; wait 15 seconds to let them cool down. NEVERtouch the surfaces of the print head thermal elements or the electronic printed circuit, as dust

and dirt can stick to their surface and cause damage by electrostatic discharge. The thermal paper contains Na+, K+ and Cl- ions that can cause harm to the print head elements.

Therefore, use only the specified paper. If the printer has not been used for long period of time and the paper was loaded, the paper could

become deformed by the drive roller pressure. It is recommended to make it advance at least 30 mmbefore printing again.

For security reasons, unplug the printer if it is not going to be used over a long period of time. Don t print continuously (without stopping) for more than 6 minutes.

CLEANING PROCEDURE AND PRECAUTIONS

In order to clean the thermal print head, proceed as indicated by the following steps:

1. Open the printer cover. Wet a cotton sponge in alcohol (ethanol, methanol or IPA), and use it inorder to clean the thermal elements of the print head and to remove the possible accumulationof paper particles found on the cover, roller and nearby surfaces.

2. Wait for alcohol to evaporate before inserting the paper roll and closing the cover.

FENIX recommends cleaning the thermal print head periodically (each 2 or 3 months) in order tokeep the print quality.

NOTES:" The print head could be hot after printing. Make sure it has thoroughly cooled down

before proceeding to clean it." Unplug the power supply cable before the cleaning." Never touch the thermal elements of the print head with your hands." Never use metallic or piercing elements for the cleaning of the print head, as they

could scratch it.

Fig a. Thermal print head cleaning

RECOMMENDATIONS

The plug have to be located near the printer and have to be easily obtainable. Before connecting any communication data cable, check the printer is working properly by executing

the self-test. Set the SM2000 in a place where the connection cables do not suffer stretching or cross with each

other.

PD160R-N (Oji Paper Co.)HP220AB1 (Mitsubishi Paper Mills Limited)

1.6- Internal buffer

The SM2000-Sand SM2000-Pprinters contains a 128 Kbytesinternal memory, whose functionality isdynamically shared by the receiving buffer and the loaded logos. In this way, the receiving buffer usesthe space not occupied by the logos. The maximum capacity allowed for the logos is 127 Kbytes,whereas the minimum capacity for the receiving buffer is 1 Kbyte.The SM2000-Uprinter contains a 512 Kbytesinternal memory. In this model, the maximum capacityallowed for logos is 511 Kbytes, and the minimum capacity for the receiving buffer is 1 kbyte.

By default, the SM2000 printer does not provide any loaded logo; therefore providing 128 Kbytes for thereceiving buffer (512 Kbytes for SM2000-U printer).

This big receiving buffer allows the printer working in the following way: Firstly, all data are buffered, and

afterwards the printing is done at the maximum possible speed, without it being affected by thecommunications time processing.

2 INSTALLATION

2.1- INTRODUCTION

The SM2000 printer should be installed horizontally on a rigid surface, avoiding locations where hightemperatures or vibration risks exist. Its location must allow the final user an easy access to all thehandling elements of the printer for their use and maintenance.

Fig. 2.1- Maintenance and use elements of the SM2000 printer

The SM2000 connectors are located in the rear part of the printer. All models include a power supplyconnector and a coins drawer connector. Depending on the communications model, the printer isprovided with a serial interface SUB-D25 connector (SM2000-S), a parallel interface CENTRONICS

connector (SM2000-P) or an USB interface connector plus a serial SUB-D9 connector (SM2000-U).

12/65

The SM2000 printer includes a connector cover in order to protect the cable connections from shock anddirt. At the same time, it avoids user contact.Once all the cables are connected, follow these steps for its installation:

1. The connector cover has three openings: left, right and rear. If needing to use any of theside openings, remove the corresponding tab by breaking it with your fingers (once a tabhas been removed, it can no longer be reinstalled).

2. After removing the tab, be sure to remove any remaining piece of plastic in order tokeep the plastic border flat and avoid any possible cable harm.3. Place the cover to its default position and assemble the two fixing screws as shown in

the following figure:

Fig. 2.3-Connectors cover

2.2- POWER SUPPLY

The SM2000 is powered by an external power supply by means of a female polarized connector of 3pins that includes a security anchor. The power supply voltage must be verified before making theconnection between the supply and the printer.

Fig. 2.4-SM2000 printer power supply connector

The power supply male connector must be a KYCON806-KPP-3Por an equivalent model.

It is not advisable to use a different power supply from the one provided by FENIX along with the printer(FAPOS-1). Using a different power supply could harm the printer or prevent it from working properly.

NOTE:The current flow increases when the number of active dots in a horizontal graphic line increases. Print

quality can decrease if the printing ratio and the printing speed are high.If the average workload of the printer is high during a long period of time, it is recommended to use thelow consumption mode (see DIP-switches 2-3, 2-4).

21/65

NOTES: Use paper rolls that meet the specifications indicated in this manual. DO NOT open the printer cover during the printing operation. Close the cover correctly, checking that the PAPER OUT LED turns off.

3.2- CLEARING A PAPER JAM

If a paper jam occurs, please proceed as indicated in the following steps:

1) Switch the printer off and press the button in order to try and open the cover.2) If the paper is jammed with the cutter and the cover can not be opened, then the cutter

posit ion must be restored: remove the screw located on the right side of the prin ter, inset a

philips screwdriver ( 3mm) until search the cutter continuous screw, and turning it until the

cover can be lif ted easily.

Warning: Never force the opening of the cover, as the cutter blade could bend and becomepermanently damaged if the paper is jammed with it.

Fig. 3.2- Manual cutter positioning.

3) Remove the jammed paper and any other remaining piece of paper. Install the paper roll in thesame way as indicated in the previous section.

3.3- BUTTONS AND SWITCHES

3.3.1- Power supply switch

It is placed on the lower front of the printer and acts as the switch of the external power supply. The frontpanel provides a POWER LED that indicates whether the power is on.

3.3.2- Paper advance button (FEED)

The FEED button in the front panel activates the automatic paper advance.The paper is advanced while the button is kept pressed. The FEED button functionality is not enabled inthe following conditions:

(1) The paper sensor does not detect paper.(2) The cover is open.(3) The ESC c 5command has been sent.

Warnings:

"DO NOT attempt to open the printer cover unless acting on the cover open button."DO NOT open the printer cover while printing."DO NOT open the printer cover while the cutter is working, as the mechanism could be

damaged.

3.3.4- DIP-Switch

The SM2000 printer provides different configurable parameters through 2 DIP-switches with 8 switcheseach. In order to access to the DIP-switch devices, proceed as indicated in the following steps:

Fig. 3.3. - DIP-switch location.

Every time the SM2000 is powered on, the printer reads the content of the DIP-switch devices, and thecorresponding configuration parameters are initialized. The functionality of the DIP-switch depends onthe communication interface used.

c) Change the switches positioning

(ON/OFF) as needed, according tothe tables described in thefollowing sections.

d) Close back the cover andsecure it with the screw.

a) Unplug the SM2000 power supply cable.

b) Remove the metal cover that hides the DIP-switch devices (which is located in the bottom sideof the SM2000) by removing the screw that holdsit.

3.4- PANEL LED

The SM2000 includes three LEDs in its front panel showing printer information.

Fig. 3.4- LEDs and FEED button.

The POWERLED (green) shows whether the SM2000 is powered on (the led is on) or it is not (the led isoff).The PAPER OUTLED (red) shows whether the SM2000 does not have any paper and/or the cover isopen (the led is on).The ERROR LED (red) shows if there has been any error in the SM2000 (the led is blinking) (Seesection: 3.6- ERRORS PROCESSING).

3.5- SPECIAL PRINTING MODES

Besides the normal printing mode, in which all the received data are printed according to the settings orconditions fixed by the commands, the SM2000 printer allows two special working modes: the self-testmode and the hexadecimal mode.

3.5.1- Self-test mode

The SMS2000 provides the self-test mode withtwo different functionality: showing information on thefeatures of that particular printer model and verifyingthe printing.

To enter the self-test mode, the printer must bepowered on while keeping pressed the paperadvance button (FEED) and with the cover closed.The SM2000 will start printing a report, whichallows checking the features of this particularmodel, like the firmware current version, controlfunctions of the communications protocol,DIP-switch settings, and so on.

If, once this printing has been finished, thepaper advance button FEED is still keptpressed, the SM2000 will start printing

continuously and repetitively a character mapuntil it finally concludes the self-test by printing* * completed * *.This second option of the self-test mode has the goal tovalidate the printing speed and quality.

Fig. 3.5- SELF-TEST mode example.


26/65


26/65

3.5.2- Hexadecimal dump mode

Fig. 3.6- Hexadecimal dump mode example.

NOTES:(1) For any received characters that are under 20h, the ASCII . will be printed.(2) During the hexadecimal dump mode, the DEL EOT command does not work.(3) It must be taken into account that if the number of bytes is not bigger than the minimum

amount required to print one line (11 bytes), the SM2000 will not print. It is recommended tocomplete the hexadecimal dump by sending at least 11 bytes (for example 00h).

(4) It is also possible to enter the hexadecimal mode through the GS ( A command.

3.6- ERROR PROCESSING

3.6.1- Error types

When an error happens, the SM2000 visually notifies the error type through the ERROR LED and thePAPER OUT LED, located in the front part of the printer. This fact allows, the final user to have a directreference on the current printer status.On the other hand, the printer status and all its possible errors can also be obtained via software throughthe DEL EOT command. In this way, the application developer can have more complete information onthe printer status, therefore being able to act accordingly.

1) The errors detected by the ERROR LED are the following: near-end paper, coins drawer open,hardware error, cutter error, power supply voltage error and printing head temperature error.

In this mode, all the data received from the hostsystem is printed, without processing any command,in hexadecimal and its corresponding ASCII.This mode can be very helpful for the applicationdeveloper during the setup test time, as it allows to

detect and eliminate possible errors (as out of rangeparameters, non valid command sequences, errors inthe communication channel, etc.), comparing what ithas theoretically been sent to the printer to what it isreally being received.

To enter hexadecimal mode, proceed with thefollowing steps:

a) Open the cover and power the printer on keepingthe FEED button pressed.

b) Close the cover. The SM2000 will print the text~~~~HEXADECIMAL MODE~~~~, and it will remainwaiting for receiving data. As soon as the receivedbytes received complete one line (11 bytes), they willbe printed automatically.

Turn off the printer to quit the hexadecimal mode.


27/65


27/65

(2) When any of these errors happen, the ERROR LED blinks with a different blinking timing sequence for each of them. This fact allows the final user to understand, by visual inspection, the error that had happened.

More information on these errors can be found below:

near-end paper erro r

[Description] This error happens when the near-end paper sensor detects that the paper roll isclose to be finished. This means that using a paper roll with an external diameter of100 mm and inner diameter of 25 mm, the sensor will trigger the error when there arestill 1.5 meters of paper approx.This indication should be really taken as a warning, not as an error as such. The action

depends on the application and the developers criteria.[Recover action] Replace paper roll.[Notes] When this error happens the printing is not interrupted, although using the ESC c 4

command could stop it. This error is different from the out of paper error.

Coins drawer open error

[Description] This error happens when the coins drawer is open.This indication should be really taken as a warning, not as an error as such. The actiondepends on the application and the developers criteria.

[Recover action] Closing the coins drawer.

Hardware error

[Description] Some of the printer hardware devices are not working properly.[Recover action] This error cannot be recovered. One of the components of the control interface might

be broken and should be replaced or repaired.

Cutter error

[Description] The cutter does not work correctly. For some reason, the cutter cannot start and comeback to its original position.

[Recover action] The printer tries automatically to recover from this error once it is initialized (ON/OFF).If there was paper jammed or any other obstacle preventing it from recoveringautomatically, the cover might not be able to open. In that case, proceed as specified insection 3.2. Clearing a paper jam.

Power supply voltage (Vp) error

[Description] The power supply voltage (Vp) is out of range (24V + 10%).[Recover action] This is a non-recoverable error.

Unplug the power supply from the printer and check if the output voltage of the power

supply is within the specified range. Replace it in case it is not working properly.

Temperature error

[Description] The print head temperature is above 80C.[Recover action] The printing recovers automatically from this error when the thermal print head

temperature is below 60C again.[Note] This error can happen if the ambient temperature is very high and the printer is working

continuously with high-density printing.

(2) The errors indicated by the PAPER OUT LED are the out of paper and/or open cover ones.

Out of paper error

[Description] The out of paper sensor detects there is not paper on the printing line.[Recover action] This error disappears loading a new paper roll in the printer (see section 3.1. Paper

loading).[Note] This error stops the printing and it cannot be restarted until it is not recovered.

Open cover error

[Description] The printer cover is open.[Recover action] This error disappears when closing the cover.[Note] This error stops the printing and it cannot be restarted until it is not recovered.

3.6.2- Printer operation when an error happens

When the SM2000 detects an error (except the near-end paper and coins drawer open errors), itexecutes the following operations:

It stops all printing operations. It changes its status to BUSY (refer to section 3.3- DIP Switches when the DIP switch 2-1 is off). The ERROR LED blinks or the PAPER OUT LED permanently lights.

NOTES:

(1) The circles represent the IEEE1284 phases.(2) This diagram can not be considered as the true state diagram.(3) The host system can request the negotiation phase at any time, but the SM2000 will on ly

return a status byte if the host system has send the DEL EOT command previously. (4) If the printer control of the host system does not have enabled or implemented the nibble mode

according to the IEEE-1284 interface, only the compatibility mode will make communication possible.

In this case, the error signaling is reduced to the information provided by the PError and nFault pins.

3.7- PAPER SENSORS

The SM2000 has two specific photo sensors for paper: out of paper and near-end paper.The out of sensor paper has the basic function of informing the printer controller about the existence ofpaper (on the printing line), as there are some actions (as an example, printing without paper) that couldseriously damage the mechanism. This error block all the printer activities related to cutting and printing.The near-end paper sensor detects when the paper roll is near its end of file. This error, by default,

does not stop printing, but through the ESC c 4 command, it can be achieved that the near-end paperdetection stops the printing. If a 25 mm inner diameter paper roll is used, the sensor will trigger when Xmeters of paper remain (approximately).The final user can detect these errors with the PAPER OUT LED and ERROR LED, and the applicationdeveloper can test them through the DEL EOT command, being able to act accordingly.

Fig.3.10-Localization of the out of paper and near-end paper sensors.

3.8- OPEN COVER SENSOR

When this sensor detects the opening of the cover, it lights the PAPER OUT LED, blocking all theactivity related to printing and cutting. The printing resumes when the cover is closed.The sensor is a micro switch sensor. The roller (once the roller is fixed in its anchor) applies pressureon the micro switch, and closes. For that reason, the cover must be closed so that it does not surpassthe chassis in any of its ends.

[Notes] n indicates the number of bar code data, and the printer processes n bytes from the next

character data as bar code data. If n is outside of the specified range, the printer stops command processing and processes

the following data as normal data. If d is outside of the specified range, the printer only feeds paper and process the following

data as normal data. If the horizontal size exceeds printing area, the printer only feeds the paper. This command feeds as much paper as is required to print the bar code, regardless of the

line spacing specified by ESC 2 or ESC 3. This command is enabled only when no data exists in the print buffer. When data exists in

the print buffer, the printer processes the data following m as normal data. After printing bar code, this command sets the print position to the beginning of the line. This command is not affected by print modes (emphasized, double-strike, underline,

character size, white/black reverse printing, or 90 rotated character, etc.), except forupside-down printing mode.

When the system of bar code is used JAN13(EAN13), the printer prints the bar code afterreceiving 12 bytes of data of the bar code and processes the following data like normal data.

The number of data for code ITF must be even numbers. When an uneven number of byteof data is introduced, the printer ignores the command.

When using the CODE 128 in this printer, take the following points into account for datatransmission:

# The top of the bar code data string must be code set selection character (any ofCODE 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.
