1. Precaution Segment

1-1 Safety Precautions

1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields.

2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices including:

nonmetallic control knobs and compartment covers.

3. Make sure that there are no cabinet openings through which people – particularly children - might

insert fingers and contact dangerous voltages. Such openings include excessively wide cabinet

ventilation slots and improperly fitted covers and drawers.

4. Leakage Current Hot Check:

WARING: Do not use an isolation transformer during this test.

Use a leakage-current tester or a metering system that complies with American National Standards

Institute (ANSI C101.1, Leakage Current for Applications), and Underwriters Laboratories (UL Publications

UL1410, 59.7).

With the unit completely reassembled, plug the AC line cord directly into a 100VAC or 240VAC outlet of the

Adaptor.

With the unit’s AC switch first in the ON position and then OFF, measure the current between a

known Earth ground (metal water pipe, conduit, etc.) and all exposed metal part, including: metal cabinet,

frame, and screw-heads and printer. The current measure should not exceed 0.1 milliamp. Reverse the

power-plug prong in the AC outlet and repeat the test.

5. Design Alteration Warning:

Never alter or add to the mechanical or electrical design of the ECR. Unauthorized alterations might create

a safety hazard. Also any design changes or additions will void the manufacture’s warranty.

6. Components, parts and wiring that appear to have overhead or that are otherwise damaged should be

replaced with parts that meet the original specifications. Always determine the cause of damaged or

overheating and correct any potential hazards.

7. Observe the original lead dress, especially near the following areas: sharp edges, and especially the AC

and high voltage supplies. Always inspect for pinched, out-of-place, or frayed wiring.

Do not change the spacing between components and the printed circuit board. Check the AC power cord

for damage. Make sure that leads and components do not touch thermally hot parts.

8. Product Safety Notice:

Some electrical and mechanical parts have special safety-related characteristics, which might not be

obvious from visual inspection. These safety features and the protection they give might be lost if the

replacement component differs from the original-even if the replacement is rated for higher voltage,

wattage, etc.

Components that are critical for safety are indicated in the circuit diagram by shading, ( )or ( ).

Use replacement components that have the same ratings, especially for flame resistance and dielectric

strength specifications. A replacement part that does not have the same safety characteristics as the

original might create shock, fire or other hazards.

1-2 Servicing Precaution

WARNING 1: First read the Safety Precaution section of this manual. If some unforeseen

circumstance creates a conflict between the servicing and safety precautions,

always follow the safety precaution.

WARNING 2: An electrolytic capacitor installed with the wrong polarity might explode.

1. Always unplug the unit’s AC power cord from the AC power source or the Power Switch off before

attempting to:

(a) Remove or reinstall any component or assembly,

(b) Disconnect an electrical plug or connector,

(c) Connect a test component in parallel with an electrolytic capacitor.

2. Some components are raised above the printed circuit board for safety.

An insulation tube or tape is

sometime used. The internal wiring is sometimes clamped to prevent contact with thermally hot

components. Reinstall all such elements to their original position.

3. After servicing, always check that the screws, components and wiring have been

correctly reinstalled.

Make sure that the portion around the serviced part has not been damaged.

4. Check the insulation between the blades of the AC plug and accessible conductive parts

(example: metal panels and input terminals).

5. Insulation Checking Procedure: Disconnect the power cord from the AC source and

turn the power switch

ON. Connect an insulation resistance meter (500V) to the blades of the AC plug.

The insulation resistance

between each blade of the AC plug and accessible conductive parts (see above) should be

greater than 1 mega-ohm.

6. Never defeat any of the B+ voltage interlock. Do not apply AC power to the unit

(or any of its assemblies)

unless all solid-state heat sinks are correctly installed.

7. Always connect an instrument’s ground lead to the instrument chassis ground before

connecting the positive lead; always remove the instrument’s ground lead last.

1-3 Precaution for Electrostatically Sensitive Devices (ESDs)

1. Some semiconductor (solid state) devices are easily damaged by static electricity. Such components are

called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-effect

transistors. The following techniques will reduce the occurrence of component damaged caused by static

electricity.

2. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge

from your body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device.

(Be sure to remove it prior to applying power-this is an Electric shock precaution.)

3. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to

prevent accumulation of electrostatic charge.

4. Do not use freon-propelled chemical. These can generate electrical charges that damage ESDs.

5. Use only a grounded-tip soldering iron when soldering or unsoldering ESDs.

6. Use only an anti-static solder removal device. Many solder removal devices are not rated as anti-static;

these can accumulate sufficient electrical charge to damage ESDs.

7. Do not remove a replacement ESD from its protective package until you are ready to install it.

Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam,

aluminum foil or other conductive materials.

8. Immediately before removing the protective material from the leads of a replacement ESD, touch the

protective material to the device will be installed.

9. Minimize body motions when handling unpacked replacement ESDs. Motions such as brushing clothes

together, or lifting a foot from a carpeted floor can generate enough static electricity to damaged an ESD.

1-4 Operational Precautions

1. The heating element of the printer mechanism’s thermal head and the driver IC are easily damaged.

Never allow these components to come into contact with metal or other hard objects.

2. Never touch the printer mechanism’s heating element with your hand. Doing so can damage the heating

element and affect proper operation.

3. The head and motor areas are very hot during and immediately after printing. Do not touch components

in these areas directly with your hand.

4. Do not use any paper other than these specified in this manual otherwise print head reliability and print

quality are affected adversely.

5. Thermal paper starts to color at around 70ºC. Take care to protect unused and printed thermal paper

against the affects of heat, light and characters on the paper to feed.

6. Take the roll paper out of the printer when you will not use the printer for a long time in a high

temperature and humidity environment.

3-5-1(e) H/W Flow Control

When DTR/DSR flow control is select, before transmitting a data, the Printer checks whether the host is

BUSY or not. If the host is BUSY, the Printer does not transmit a data to the host. If the host is not BUSY, the

Printer transmits a data to the Host. The host is the same. Refer to the Interface Part of Chapter 7 (Special

Circuit Diagrams).

3-5-1(f) S/W Flow Control

When XON/XOFF flow control is selected, the printer transmits XON(ACSII 11h) or XOFF(ASCII 13h) signal

through the TXD line.

If the Printer is BUSY, the Printer transmits XOFF(ASCII 13h) to host through the TXD line. Then the host

recognize that the Printer is BUSY. So, the host does not transmit a data to the Printer. If the Printer is

released from BUSY, the Printer transmits XON(ASCII 11h) to host through the TXD line. Then the host

recognize that the Printer is not BUSY. And the host transmit a data to the Printer.

※ Note: Refer to the Operation Manual about XON/XOFF flow control.

3-5-2(b) Reverse Mode Specification (Nibble / Byte mode)

Data transmission from the printer to the host computer.

The STATUS data transmission from the printer to the host computer is accomplished in the Nibble or Byte

mode. This mode allows data transmission from the asynchronous printer under the control of the host

computer. Data transmission in the Nibble mode are made via the existing control lines in units of for bits

(Nibble). In the Byte mode, data transmission in accomplished by making the 8-bit data lines bidirectional.

Neither mode can operate at the same time as the compatibility mode, so switching is always required.

USB cable consists of four conductors, two power conductors, and two signal conductors.

High-/full-speed cable consists of a signaling twisted pair, VBUS, GND, and an overall shield. High-/full

speed cable must be marked to indicate suitability for USB usage. High-/full-speed cable may be used with

either low-speed, full-speed, or high-speed devices. When high-/full-speed cable used with low-speed

devices, the cable must meet all low-speed requirements.

Low-speed recommends, but does not require the use of a cable with twisted signaling conductors.

※ Note: Minimum conductor construction must be stranded tinned copper.

To minimize end user termination problems, USB uses a keyed connector protocol. The physical difference

in the Series A and B connectors insures proper end user connectivity. The A connector is the principle

means of connecting USB devices directly to a host or to the downstream port of a hub. All USB devices

must have the standard Series A connector specified in this chapter. The B connector allows device vendors

to provide a standard detachable cable. This facilitates end user cable replacement.

Figure 2-10 illustrates the keyed connector protocol.

The following list explains how the plugs and receptacles can be mated:

• Series “A” receptacle mates with a Series “A” plug. Electrically, Series “A” receptacles function as outputs

from host systems and/or hubs.

• Series “A” plug mates with a Series “A” receptacle. The Series “A” plug always is oriented towards the host

system.

• Series “B” receptacle mates with a Series “B” plug (male). Electrically, Series “B” receptacles function as

inputs to hubs or devices.

• Series “B” plug mates with a Series “B” receptacle. The Series “B” plug is always oriented towards the USB

4-3-3 Buzzer and Cash Drawer Circuits

1) Buzzer Driving Circuit

The Buzzer is used to inform several kinds of states which occur under system operating and gives some

information to users by controlling the CPU (SPEAr300)

[Figure 4-6 Buzzer Block Diagram]

2) Cash Drawer Driving Circuit

The circuit is used for opening cash drawer and driven by the Q301, Q302(2SD2170). When its state is high

level signal, Q301 or Q302 (2SD2170) drive the solenoid to open the cash drawer. As an optional item, we

provide sensor switch (we call it a compulsory switch) which checks the drawer whether it is opened or not.

This sensor switch turns on for the drawer open condition, and turns off for the other.

※ Caution: Make sure that the Cash Drawer solenoid resistance is more than 20Ω.

4-3-9 Thermal Printer Head Circuit

First, the CPU sends a Serial Clock and Serial Data 256bits(32Bytes) to the Shift Register of the Thermal

Printer. The Serial Data are stored to each Shift Register in the Thermal Printer. Because the Data#1 Pin and

the Data#2 pin are shorted on Main PCB, the Data(256bits) are stored in both Shift Register#1 and #2.

Second, the CPU send a Latch Signal to the Thermal Printer. Then, the Data of both Shift Register#1 and #2

(256*2=512bits) are moved to the Latch Register. After that, the CPU sends a Strobe Signal to the Thermal

Printer. Then, the Printer outputs the Serial Data. Each Strobe Signal manages the Printer Dot.
