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.

Notes: 1. When frequent paper jams occur near the aligning roller by using special thin paper other than specified, the aligning value can be changed (reduced) as a measure. However, when the aligning value is reduced excessively, this may possibly cause the registration to be shifted. Therefore, make sure that no registration shifting occurs while adjusting the value. 2. Long size adjustment is used as the base when there are both long and short adjustments.
1.5.3
Registration adjustment
Incorrect registration (or top margin) may occur due to paper quality, feed roller surface condition, etc. besides, misadjustment. Check these items before starting adjustment.
Note: When the adjustment value of the cassette is changed, the registrations by all the other feedings will be shifted correspondingly. Therefore, be sure to check all other registrations after the cassette adjustment. However, each adjustment other than the cassette can be performed individually.

Code to be used in the test mode "05": "38": Main charger "39": Transfer charger "40": Separation charger "43": Developer bias (The output check uses code "38")
Notes: 1. Clear the drum counter (mode "08", code "76") to "0" when the drum is replaced with a new one. 2. When carrying out adjustments of the main, transfer and separation charger output, refer to the points below. · Adjustment codes "39" and "40" are not used if developer material is inside (Error code "C35"). · Adjustment codes "39" and "40" are used to perform detection of the remaining developer material for 15 sec. (adjustment is impossible during this period). · The input value can be adjusted after the remaining developer detection is finished. · If detection has already been performed once, detection of the remaining developer material cannot be performed unless disconnection and connection of the developer unit connector are done. 3. Use a digital tester with an input impedance of 10M or over.

[C] Output adjustment procedure Caution: · When pockmarks occur: When pockmarks (irregularities) are generated on the halftone areas, reduce the output in accord ance with the adjustment procedure described on the previous page. Note: Do not reduce the output excessively. Otherwise, the separation ability will decrease. · Defective separation: When defective paper separation occurs despite the charger wires being clean, or when the user is likely to use a large quantity of thin paper, raise the output in accordance with the adjustment procedure described on the previous page. Note: Do not increase the output excessively, otherwise pockmarks will be generated and the separation ability will decrease. · When developer bias output is adjusted: If backgrounding occurs over the entire copy with no under-exposure conditions, increase the bias output. However, increasing it excessively would result in poor image contrast, bias leakage or adherence of carrier powder to the drum surface.

[A] Focus and horizontal reproduction ratio adjustment for 100% (1) Make an actual size-copy and check the focus and horizontal reproduction ratio. If adjustment is necessary, the adjustment data must be re-entered as follows. · Poor focus and reduced horizontal reproduction ratio: reduce the mirror position data (code 61). · Poor focus and enlarged horizonal reproduction ratio: increase the mirror position data (code 61). · Good focus, but reduced horizontal reproduction ratio: increase the lens position data (code 60). · Good focus, but enlarged horizontal reproduction ratio: decrease the lens position data (code 60).
Notes:
1.
The focus and horizontal reproduction ratio change when the lens or the mirror is moved. But the lens position data mainly change the horizontal reproduction ratio and the mirror position data mainly change the focus.
2. 3. 4. 5.
The horizontal reproduction ratio should be adjusted after adjusting the focus, then check the focus again. If the horizontal reproduction ratio is incorrect (within ±0.5%), it will not be possible to achieve good focusing. Because of the lens characteristics, there is a greater margin for focusing at the center of the image than at the corners. For 200% and 50%, the horizontal reproduction ratio (lens position) will automatically assume the optimum condition when the focus (mirror position) is adjusted. So, horizontal reproduction ratio adjustment is not normally necessary.
[B] Focus and horizontal reproduction ratio adjustment for 200% (1) (2) Make a 200% copy and check the focus and horizontal reproduction ratio. If the focus and horizontal reproduction ratio are poor, re-enter the data of code 63 to adjust them. Adjustment of code 62 is usually unnecessary. [C] Focus and horizontal reproduction ratio adjustment for 50% (1) (2) Make a 50% copy and check the focus and horizontal reproduction ratio. If the focus and horizontal reproduction are poor, re-enter the data of code 65 to adjust them. Adjustment of code 64 is usually unnecessary.
