6. PRECAUTIONS BEFORE USE

6-2. PRECAUTIONS FOR STACKING PAPER

• If the paper is not stacked neatly on the paper feed table,

the unit will not be able to read the size of the paper

accurately and as a result, may determine the paper as

outside the standard size. Therefore, be sure to stack the

paper neatly.

The paper feed table has a built-in device for readingpaper size.Take note that this device will not be able to read thepaper size correctly if the paper is stacked unevenly.This may as a result cause problems.

• Automatic paper size detection can be carried out for

paper up to ±2.5 mm of the fixed paper.

• If the paper is not stacked properly lengthwise, mis-feed

or chain feed may occur.

• When stacking just a few sheets of paper on the paper

feed table, lower the paper set lever while pressing the

back edge of the paper.

• If the paper flowing into the folding plate is folded

without reaching the stopper due to conditions

such as environmental conditions (temperature,

humidity), paper quantity, its type, paper couch

conditions, folding speed, curling etc., it may not

be folded properly.

• In some cases, the paper may also coil around the

rubber roll and cause problems.

• As such problems can be corrected by decreasing

the folding speed, keep decreasing the speed until

the paper is folded properly.

23


11 Check the folded paper for testing.

• Proceed onto the next step if the sheets of paper

have been folded satisfactorily.

Check the second ejected paper to confirmthat folding is performed correctly.

• If the sheets of paper have not been folded

satisfactorily, refer to the following steps.

óIf folding has slipped in the vertical direction:

Press the “folding stopper adjustment” button and

adjust the folding slippage.

Refer to “Adjusting the folding slippage in the

vertical direction” on page 36.

7-3. DOUBLE FOLDING THICK PAPER


• When thick paper (above 105 g/u) such as fine

quality paper, etc. is folded into fours, its thickness

may cause its folds to open when it is ejected to the

stacker. As a result, the paper will not be able to

pass through the stacker rolls and paper jam will

occur.

Note : Take note that paper below B6 size(157 g/m2) cannot be ejected if foldedinto fours.

• In this case, proceed in the following steps.

9. USING ART/COATED PAPER• Art/coated paper are difficult to fold as their printed surfaces tend to stick together

easily and cause double feeding.• When folding such a kind of paper, observe the following precautions before starting

folding operations.

1 Loosen the paper thoroughly.

2 Next arrange the paper neatly andstack them on the paper feed table.

3 For other precautions, refer to“Precautions for Stacking Paper” onpage 16.

9-1. PRECAUTIONS FOR STACKING PAPER

Paper

Paper set lever

42

9-2. OPERATING PRECAUTIONS

1 If double-feed occurs frequently andcannot be corrected, reduce theamount of paper on the paper feedtable until the middle of the guide(approx. 25mm)

As the specific gravity of this type of paper ishigher than that of normal paper, they tend tostick together, causing double-feeding tooccur frequently.The amount of paper loaded on the table istherefore reduced.

2 Adjust the paper feed pressureadjusting lever to “3”.

• If the paper slips, gradually raise the paper feed

pressure one level at a time , from “3” to “4”, until

the appropriate paper feed pressure is obtained.

• When the paper slips, the display shows “-¡-”

and the unit will stop. Raise the paper feed pressure

one level when the unit stops.

Set the paper feed pressure within the rangeof 3 to 5.

3 Next, open the top cover and adjustthe separator pressure.

• Set the separator pressure adjusting dial to “2.5”.

• If the paper sticks and several sheets of paper are

fed at one time (double feeding), gradually raise

the separator pressure adjusting dial 0.5 at a time

until the appropriate separator pressure is obtained.

Set the separator pressure within the range of2.5 to 3.5.

• The separator pressure may have to be set to 3.5 or

above if the paper feed ring or paper separator, etc.

is worn out.

But try to set the pressure at the lowest level

possible.
