GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER 4560/4570

The installation and service should be done by a qualified service technician.

1.Transportation/Installation

•When transporting/installing the copier, use two persons and be sure to use the positions as indicated below.

The copier is fairly heavy and weighs approximately 95 kg (210 lb), therefore pay full attention when handling it.

2.Installation

•Be sure to use a dedicated outlet with AC 115V/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 and fasten them with screws.

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 such as the lamp terminal, etc. and rotating/operating sections.

•Use suitable measuring instruments and tools.

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” etc. to see if there is any dirt on their surface or 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 packing materials, 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.

1.3Auto-Toner Sensor Adjustment

When the developer material is replaced, the auto-toner sensor needs to be adjusted.

Notes:1. If the high voltage (main/transfer/separation charger) output adjustment is combined, high voltage adjustment should be performed first before the developer material is loaded into the developer unit.

2. Make sure that the drum blade is pressed to the drum before the auto-toner adjustment.

<Procedure> (Use code “0” in the “05” mode.)

(1)Install the process unit into the copier (the main blade should contact with the drum).

(2)Press the keys “0” and “5” at the same time and turn on the power switch.

The following display appears indicating that the adjustment mode has been entered.

0 5					AJ
				TEST MODE A	100%
READY

(3)Enter “0” using the digital keys and press the PRINT key. The following display will appear.

								(Example)		A
0								128		0
			PRINT				WAIT	147%

B

Note: B : Indicates the output voltage of the auto-toner sensor. (The above example is only a typical value.) The above display indicates an output voltage of 1.47V.

The drum, developer unit, etc., are operating at this time.

(4)After approximately two minutes, the A and B displays on the message display will automatically begin to change.

0

A few minutes later	%
WAIT

(5)After a short time, the A and B displays on the message display will automatically stop changing and, at the same time, the message will also change as shown below.

(Example)

	148	0
ADJUST MODE	240%

(The numerical values shown above for A and B are only typical values.)

Note: The numerical value displayed in B may vary in the range of ±4 or less.
