HOW TO USE THIS SECTION

ADJUSTMENT

[1] Scope and Precautions

This section provides detailed information about the adjustment items and procedures. Before addressing customer complaints, perform the following checks:

1. Check whether the power supply voltage meets the specifications.

2. Check whether the power supply is properly grounded.

3. Check whether this machine shares the power supply with any other machine that draws large current intermittently (e.g., elevator and air conditioner that produce electrical noise).

4. Check whether the installation environment is good. a. The machine must be installed in a properly

ventilated area not exposed to high temperature, high humidity , and direct sunlight.

b. The machine must be installed on the

horizontal floor.

5. Check whether original has a problem to cause the defective image.

6. Check whether the selected density value is correct.

7. Check whether the surface of the platen glass and the bottom of the RADF are clean.

8. Check whether correct paper is used for cop ying.

9. Check whether copying materials and parts (e.g., developer, drum, and cleaning blade) are replenished and replaced when they reach the end of the useful life.

10. Check whether toner remains.

4. T ak e care not to damage the drum with tools and so on.

5. Do not touch IC pins with bare hands.

1 ADJUSTMENT

When servicing the machine, observe the following precautions:

1. Only either side of the AC line is shut off when the main power of this machine is turned off. Always unplug the power cord bef ore starting the service work. If it is necessary to service the machine with the power on, take care not to be caught in the scanning gear of the exposure unit.

2. Special care should be taken when handling the fixing unit because it operates at extremely high temperatures.

3. The developing unit has a strong magnetic field. Keep watches and measuring equipment away from it.

* When adjustments must be made in order of precedence, numbers will be shown in circles.

Cautions:

• When a damaged control board is replaced, the memory board on this board must be used on the new control board. Only when the memory board is also damaged, use a new memory board on a new control board. Since the new memory board does not have adjustment data, the above adjustments are required. Before making the above adjustments, make the “47-92” setting to make the new memory board effective.

• After making any adjustment, make the “”47-96" setting so that this adjustment value can be restored simply by making the “47-93” setting even if another adjustment is made later.

• Various adjustments (stapling stopper position adjustment, f olding stopper position adjustment) must be made to the FNS (FS-108BM) and an adjustment (cover sheet tray size adjustment) must be made to the PI (PI-108).

Note 1: Bit 7 of DIP SW6 (potential control performed/not performed) is set to determine whether potential

control is to be performed using the drum potential sensor. This setting is used to check whether the image quality has been deteriorated due to a faulty drum potential sensor.

1 ADJUSTMENT

Fixing may be insufficient in the morning if the temperature of the place where the machine is installed is low. To prevent this, increase the warm-up time (fixing upper roller initial rotation time) to allow the fixing lower roller to be warmed up to the normal temperature. This bit specifies the condition(s) under which initial rotation of the fixing upper roller is required.

• Low temperature: Initial rotation of the fixing upper roller is carried out only under the low temperature condition.

• Low and normal temperatures: Initial rotation of the fixing upper roller is carried out under low and normal temperature conditions.

• Low, normal, and high temperatures: Initial rotation of the fixing upper roller is carried out under low , normal, and high temperature conditions.

* 24 Selection of area to be erased in non-original area

automatic erasure This bit is used to make a setting associated with the non-original automatic erasure mode (application function).

1. Selection of the area to erase

There are two methods for selecting the area to be erased, “rectangular erasure” and “ tilted erasure.” Select the desired method.

· Tilted erasure: The original is not rectangular (e.g., circular original).

· Rectangular erasure: The original is rectangular (e.g., original of a standard size). If a rectangular original is placed in a tilted position, black stripes may appear in the “rectangular erasure” mode. If there is a b lack area on the periphery of the original, this area may be judged as being outside the original, resulting in improper erasure of the area outside the original. In such a case, the “rectangular erasure” mode is selected automatically.

2. Selection of identification level

When the original is dark or external light (from the fluorescent lamp or sun) enters the machine, it becomes sometimes difficult to discriminate between the area inside the original and the area outside it. In such a case, the original area identification level can be changed.

Remarks:

In the key operator mode, you can use the memory switch that has a non-original area automatic erasure function. This memory switch allows you to select the area to be copied when copy paper is selected manually.

• To copy only image size area determined by the APS sensor, select “Erase the area outside the original.”

• To copy the entire area of the original to the selected paper, select “Do not erase the area outside the original.”

Note:

The APS sensor is effective if copy paper is selected manually.

Mode Standard Dark original Darker original Interference light Uneven stripes Standard

* For rectangular original density (dark original

/darker original)

Use this mode to set the density level threshhold value to the dark when copying a news article on a newspaper.

(This mode is for copying a ne wspaper whose texture color is dark. Margin for interference light decreases.)

* As a prev entive measure to cope with the non-

standard original density(appearance of uneven stripes)

Use this mode to suppress uneven stripes appearing on a copied paper when copying a newspaper whose texture color is dark.

(Margin for interference light decreases.)

* Threshold for coping with interference light

Use this mode to increase the probability of copier to operate normal, when it is hard to prevent interference light penetrating to scan area, and when copying comparatively low density (bright texture color) original.
