GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER

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

1. Transportation/Installation

• When transporting/installing the copier, move it by the casters while lifting the stoppers. The copier is quite heavy and weighs approximately 250 kg (551 lb), therefore pay full attention when handling it.

• Be sure to use a dedicated outlet with AC 115V or 120V/20A (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.

2. 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, the transfer belt and the highvoltage transformer.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, 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.

• 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.

3. 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.

4. 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.

Page 3

5. 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.

6. 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.

7. Basically, the machine should not be operated with any parts removed or disassembled.

8. 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 RAM-IC’s (including lithium battery)

according to the manufacturer’s instructions.

Vorsicht : Entsorgung des gebrauchten RAM-IC’s (inklusive

der Lithium Batterie) nach Angaben des Herstellers.

1.2 Self-Diagnostic Modes

[

]

This copier is a multi-function copier (net work printer, DSS). So, compared with conventional copiers:

1) It has more setting items in the self-diagnostic mode.

2) Setting items are related to each other. For this reason, if normal operations are continued on the control panel (by [0] + [9] or [C] keys) when adjustments are completed, operation trouble (e.g. machine lock) may occur due to the internal structure of the program. So, when the self-diagnostic mode in adjustments after unpacking, servicing or preventative maintenance, first turn the power OFF before handing the copier over to the user.

When the K-SRAM as a service part is installed, the setting mode "08-203" must be changed at "0". When it is set at "1" the copier may not be able to operate.

Due to the error of an optical component such as the galvanomirror or an error caused by the passing time of the housing, if the beam positioning adjustment is not finished correctly, an temporary countermeasure will be brought about and a mode in which printing can continue to operate be applied. (if the HSYNK is not taken, printing is impossible). If there is an error in the galvanomirror, then correction control is not performed and "Service Call" is displayed so the copier stops. When image deterioration is allowable, copier can be used without any judgement as to whether adjustment has been finished or not. This can continue until a replacement unit is available and service technician can use this mode for that purpose.

If paper runs out during printing with the bypass, "automatic start or not" is set after paper has been added to the bypass.

Function Clear when there is no key copy counter. When the key copy counter or the card is pulled out, all the setting contents will be cleared. Only when the setting value of 08/202 is 2 or 3, this function is effective.

1.7 Automatic Adjustment of Gamma correction

(1) At the time of unpacking

When the gradation reproduction deviation is too large, it can be corrected by the automatic adjustment of gamma correction. This adjustment shall be done upon user’s request when the gradation reproduction is too high or too low.

(2) When any of the following parts are replaced, check the image and judge whether adjustment is

necessary or not.

• Exposure lamp • Indicator unit with shading board

• Lens unit • Laser optical system unit

(3) When any of the following parts is replaced or adjusted, check the copy image and determine the

necessity of this adjustment.

• Optical system position (CRG1, CRG2 position) • Mirror 1, 2, 3

• Reflector • Drum • Developer

• Main charger • Development bias • Transfer/bias

Note: This adjustment must be done only after the image adjustment described in 1.5.

After this adjustment, the image density adjustment described in 1.6 must be done.

of gamma correction

[Procedure] (1) Turn on the power switch with [0] [5]. (2) Select A3 or LD paper for the output paper size. (3) Press the [2] key and then [ENERGY SAVER] key.

(One copy of the 33-gradation pattern is outputted.)

(4) Confirm that there is no blank or line on the gradation pattern outputted in

the above step (3) and the density changes gradually. If there is any problem in the gradation pattern, repeat the step (3) to output a gradation pattern again.

(5) Face the darker side of the output gradation pattern to the original scale at

the exit side and put it on the original glass with the printed face down.

(6) Input the code [580] through the control panel and press the [START] key.

(The scanner automatically reads the original and the operation for the automatic adjustment of gamma correction will be done. About 10 seconds)

(7) When the operation completes normally, the machine returns to the stand-

by status. If the operation ends abnormally, “TEST MODE ERROR” will be displayed. (See the indication on the next page.) For the abnormal ending, press the [C] key to release the error indication. When released, the display on the control panel returns to the stand-by status. Check the position, direction and skew of the gradation pattern on the original glass, and repeat the steps from (5).

• The carrier in the developer adheres to the photosensitive drum, and scratches tend to occur

more easily on the cleaning section.

Checking the operation of empty detection lever

(1) Move the empty detection lever up/down by

hand. When the lever goes down, check that the leading edge of the lever is always in the concave of the empty sensor (as shown in the illustration.).

(2) This operation should be repeated several

times, to ensure that no error condition occur. (as shown in the illustration.)

(Supplementary) When determining the adjustment amount for the horizontal deviation, make copies using the following mode. Decide the amount observing the 8th, 9th and 10th copy images.

[Mode] Original: A4 size (or LT size) manually placed original (2 sheets) Paper sheet: A4 size (or LT size) (LCF paper feeding is preferable.) Single-sided original → Duplexed copies, Group mode copy Quantity: 10 sheets

(Supplementary) Several sheets from the head stacked in the Duplexer will be fed right after stacked for the purpose of increasing efficiency of duplex copying. At this time, stacking operation comes as first priority so the width guide of the Duplexer becomes slightly wider than that of other feeding operation (2mm exterior from both edges of the paper). Depending on the mode, the timing to switch the width guide position changes. Thus, make copies using always the above mode and procedure described in (Supplementary) of [C] to make precise horizontal deviation adjustment.

1.18 Adjustment of Developer Polarity Position

As the developer polarity position is determined by the magnet roller and polarity fixing bush, no adjustment is necessary.

1.19 Adjusting the Heat Roller Pressure

Normally, the heat roller pressure need not be adjusted. However, it must be carried out when wrinkles frequently appear on copies made on plain paper.

<Procedure> (1) Make an A3 size copy (entirely black) with the ADF open. (2) Turn the power switch OFF after copying is finished. (3) Quickly open the front cover, and draw out the belt transport unit. (4) Insert the copy made in (1) into the fuser inlet guide with the entirely black side facing down then

turning the jam release lever CCW until the center of the copy paper is nipped by the heat roller. (5) After approx. 20 seconds, take the copy paper out by quickly turning the jam release lever CCW

again. (6) Measure the width of the section of the copy paper nipped by the heat rollers at the both front and

rear sides.

1.20 Setting the Heat Roller Temperature and Heat Roller Pressure

The fuser has been set (heat roller surface temperature: 200˚C, pressurizing pressure: 100 kg) taking the fusing performance, wrinkling, curling and toner transfer deficiency on the leading/trailing edge of duplexing copy into consideration when our company recommended paper is used. This is to allow the characteristics of the paper to be demonstrated in a well-balanced manner. However, various types of paper are used in the field, and factors such as the paper thickness and surface flatness greatly affect the fusing performance, in particular. If the fusing performance deteriorates while using a specific type of paper, adopt the following procedures to cope with each case:

Increase the preset temperature of the heat roller surface by keying in the temperature with the

control panel.

Increase the pressurizing pressure of the heat rollers by inserting spacers in the pressure springs.

Carry out both 1 and 2.

Perform this procedure in order

to 3 while confirming the effect and adverse influence of the adjust-

ment.

<Procedure

: Increase the preset temperature of the heat roller surface>

Change the heat roller preset temperature (when the copier is ready) by code 411 in setting mode (08). The default is “8” (200˚C), and can be changed within the range “8” to “11” ((200˚C to 209˚C).

Notes: 1. When a large value is set (to increase the temperature), the level of wrinkling, curling and toner

transfer deficiency on the leading/trailing edge of duplexing copy tend to worsen.

2. Do not set the temperature to value larger than “12” (210˚C or more). The fuser thermostat actuates to turn the power OFF, and the thermostat must be replaced.

1 - 77 ADJUSTMENT

Page 85

<Procedure 2: Increase the pressurizing pressure of the heat rollers.> (Carry this out when procedure

does not produce the desired result. If the preset value has been

changed in procedure (1), it must be returned to its original value before this procedure is carried out.)

Insert spacers (WAS-15-105-FUS) under the pressurizing spring as shown in the figure to increase the pressurizing force. (Up to three spacers may be inserted on one side.) Inserting one spacer on each side increases the pressurizing force by 5kg. This means that the current force of 100kg can be increased to 115kg (when a total of six spacers, three on each side, are inserted).

Notes: 1. The spacers must be inserted under the spring as shown in the figure below.

2. The same number of spacers must be inserted at the front and rear sides. (Skew occurs when a different number of spacers are inserted on the front and rear sides.)

3. Do not insert four or more spacers on one side. (The spring may deform.)

4. When the pressure is increased, the level of wrinkling, curling and toner transfer deficiency on the leading/trailing edge of duplexing copy tend to worsen.
