TOSHIBA TEC CORPORATION

GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR DP1600/2000/2500 SERIES
The installation and service should be done by a qualified service technician.

1. Transportation
· When transporting/installing the copier, employ two persons and be sure to use the positions as indicated below. The copier is fairly heavy and weighs approximately 50 kg (110 lb), therefore pay full attention when handling it.

4 portions

2. Installation
· · · · · · Be sure to use a dedicated outlet with AC 115 or 120V/15A (220V, 230V, 240V/10A) or more for its power source. The copier must be grounded for safety. Never ground it to a gas pipe or a water pipe. Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and direct sunlight. Also provide proper ventilation as the copier emits a slight amount of ozone. To insure adequate working space for the copying operation, keep a minimum clearance of 80 cm (32") on the left, 80 cm (32") on the right and 10 cm (4") in the rear. After having installed the copier, be sure to push the carrying handles into the copier.

3. Service of Machines
· · · · · · Basically, be sure to turn the main switch off and unplug the power cord during service. Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the damp heater and their periphery. Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer. Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fans, etc. When servicing the machines with the main switch turned on, be sure not to touch live sections and rotating/operating sections. Avoid exposure to laser radiation. Use suitable measuring instruments and tools.

1600/2000/2500 GENERAL PRECAUTIONS

·

Avoid exposure to laser radiation during servicing. Avoid direct exposure to beam. Do not insert tools, parts, etc. that are reflective into the path of the laser beam. Remove all watches, rings, bracelets, etc. that are reflective.

4. Main Service Parts for Safety
· The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important for safety. Be sure to handle/install them properly.

5. Cautionary Labels
· During servicing, be sure to check the rating plate and the cautionary labels such as "Unplug the power cord during service", "Hot area", "Laser warning label" etc. to see if there is any dirt on their surface and whether they are properly stuck to the copier.

6. Disposition of Consumable Parts/Packing Materials
· Regarding the recovery and disposal of the copier, supplies, consumable parts and packingm a terials, it is recommended to follow the relevant local regulations or rules.

7. When parts are disassembled, reassembly is basically the reverse of disassembly unless otherwise noted in this manual or other related documents. Be careful not to reassemble small parts such as screws, washers, pins, E-rings, toothed washers in the wrong places. 8. Basically, the machine should not be operated with any parts removed or disassembled. 9. Precautions Against Static Electricity
· The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband, because the ICs on it may become damaged due to static electricity. Caution: Before using the wrist band, pull out the power cord plug of the copier and make sure that there is no uninsulated charged objects in the vicinity. Caution: Dispose of used batteries and RAM-ICs including lithium batteries according to the manufacturer's instructions. Attention: Se débarrasser de batteries et RAM-ICs usés y compris les batteries en lithium selon les instructions du fabricant. Vorsicht: Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive der Lithium-Batterie) nach Angaben des Herstellers.

Explanation of status display When the sensor test is carried out, the status of each sensor is indicated on the display with 0 or 1. Each signal is divided into 8-bit blocks. The character on the left edge of the display indicates as follows: A: Signal input to ASIC I: Signal input to the IO port S: Signal from the scanner or R/ADF P: Signal from the option connected to the PFC The display is switched using the or key.

Example 1: Confirm whether the front cover is open or close. The front cover is equipped with the 24-V ON/OFF switch (Interlock switch) and the front cover switch. The status of both switches is 1 when the cover is open, and 0 when it is close. When the status of the one is 0 and that of the other is 1 as shown in the example, there is something wrong with either of these switches.

Example 2: Confirm whether or not the optional memory PWA is installed, with the status of bits 6 and 7 of IO1 on the display. As shown in the table below, bits 6 and 7 detect the upper slot and lower slot, respectively. The installation of the memory PWA can be confirmed with these bits.
