(8) Ensure that the power sockets and plugs are not cracked or broken in any way . Any such defects should be repaired immediately. Take care not to cut or damage the power cable or plugs when moving the machine. (9) Use caution during thunder or lightening storms. Dell recommends that this machine be disconnected from the power source when such weather conditions are expected. Do not touch the machine or the power cord if it is still connected to the wall socket in these weather conditions. (10) Avoid damp or dusty areas, install the printer in a clean well ventilated location. Do not position the machine near a humidifier. Damp and dust build up inside the machine can lead to overheating and cause a fire. (11) Do not position the printer in direct sunlight. This will cause the temperature inside the printer to rise possibly leading to the printer failing to work properly and in extreme conditions could lead to a fire. (12) Do not insert any metal objects into the machine through the ventilator fan or other part of the casing, it could make contact with a high voltage conductor inside the machine and cause an electric shock. 1-2 Service Manual Precautions 1.2.3 Handling Precautions The following instructions are for your own personal safety , to avoid injury and so as not to damage the printer (1) Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause the printer to tip or fall. (2) The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your fingers, hair or clothing in any of these rotating devices. (3) Do not place any small metal objects, containers of water , chemicals or other liquids close to the printer which if spilled could get into the machine and cause damage or a shock or fire hazard. (4) Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a humidifier or heater. Damage could be caused to the printer in such areas. (5) Do not place candles, burning cigarettes, etc on the printer , These could cause a fire. 1.2.4 Assembly / Disassembly Precautions Replace parts carefully, always use Dell parts. Take care to note the exact location of parts and also cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly . Please carry out the following procedures before dismantling the printer or replacing any parts. (1) Check the contents of the machine memory and make a note of any user settings.

After installation, double check that the printer is stable. 1-4 Service Manual Precautions 1.3 ESD Precautions Certain semiconductor devices can be easily damaged by static electricity . Such components are commonly called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity. Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 1. Immediately before handling a semiconductor component or semiconductor-equipped assembly , drain of f any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially avail able wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assem bly. 3. Use only a grounded tip soldering iron to solder or desolder ESDs. 4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ESDs. 5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs. 6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a compa rable conductive material. 7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed. 8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit. 9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one’ s foot from a carpeted floor , can generate static electricity suf ficient to damage an ESD. 1.4 Super Capacitor or Lithium Battery Precautions 1. Exercise caution when replacing a super capacitor or Lithium battery . There could be a danger of explosion and subsequent operator injury and/or equipment damage if incorrectly installed. 2. Be sure to replace the battery with the same or equivalent type recommended by the manufacturer. 3. Super capacitor or Lithium batteries contain toxic substances and should not be opened, crushed, or burned for disposal. 4. Dispose of used batteries according to the manufacture’ s instructions.

The AV power controls the switch with the Triac, a semiconductor switch. The ON/OFF control is operated when the gate of the Triac is turned on/off by Phototriac (insulting part). In other words, the AC control part is passive circuit, so it turns the heater on/of f with taking signal from engine control part. When the HEATER ON signal is turned on at engine, the LED of PC501 (Photo Triac) takes the voltage and flashes. From the flashing light, the Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of Triac and flows into the Triac. As a result, the AC current flows in the heat lamp, and heat is occurred. On the other hand, when the signal is of f, the PC501 is off, the voltage is cut off at the gate of Triac, the Triac becomes off, and then the heat lamp is turned of f.
