ards.

7 If the power plug or cord becomes abnormally hot, first turn off the power switch

and disconnect the power plug from the outlet.

If used continuously in this state, fire and electrical hazards may result. Contact

your dealer.

4 Do not bind up the power cord even if it is too long, or this will cause poor heat

emission and fire hazards as a result.

5 Do not touch the power plug with wet hands, or electric hazards may result.

5. NAMES AND FUNCTIONS OF THE CONTROL PANEL PARTS

This button is used to memorize the stopping position of the folding stopper, stacker,

etc. when moved in special folding modes such as cross folding and non-fixed folding

modes, etc.

Up to two registration methods can be memorized. Once memorized, the registered

data is preserved even after the power is turned off.

To erase the registered data, keep pressing the corresponding registration button (1) or

(2) until the buzzer sounds.

This button is used to register the correction value when the folding stopper is adjusted

finely in the fixed folding mode.

Up to 36 types (No. of fixed folding modes x paper type) of correction values can be

registered.

To erase the registration, select the folding mode of the corresponding paper size to be

delected and continue pressing this button until the buzzer sounds.

This window displays the number of processed sheets (counter), the values input for

paper length, error messages, etc.

This window displays the size of paper placed on the paper feed table which is

automatically determined (fixed sizes of A3 to B6).

Also displays the operation state “ O . P” when the paper length is input.

This window displays six types of fixed folding modes.

The display lamp blinks when a mode registered for folding correction is selected.

This lamp lights up when the special folding mode is set.

This mode cannot be selected if no special folding method has been registered.

• Straighten folded or curled paper before use.

• Make sure that the ink on the paper has dried up properly

before use.

If the ink has not dried properly, it may dirty the

machine, and cause other problems such as dirtying the

folded surface with ink, etc.

6. PRECAUTIONS BEFORE USE

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 reading

paper size.

Take note that this device will not be able to read the

paper 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.

6. PRECAUTIONS BEFORE USE

• Adjust so that the front part of the paper touches the

paper feed ring in front lightly. (Arrow)

• The paper will be folded as shown in the figure if placed

with the printed surface up on the paper feed table.

• For “accordion fold” and “irregular accordion fold”, the

printed surface of some paper will be folded outwards.

6-3. GENERAL PRECAUTIONS

6. PRECAUTIONS BEFORE USE

1 Occasionally make sure that the

power plug is not abnormally hot.

If the power plug is abnormally hot, contact

your nearest dealer.

2 Make sure that the power cord is not

frayed nor scratched.

3 Connect the power plug to the

electrical outlet properly upon use.

4 When not using the unit over a long

period of time, turn on its power

occasionally.

The unit has a built-in battery to protect the different

types of data registered.

• The battery is used when the power of the unit is

off. (It will be used even if there is nothing

registered.) It is charged when the power is on.

• As the data registered and set will be lost when the

battery has worn out, be sure to keep a copy of it.

• The battery will wear out when the unit has been

left off continuously for about three months. Turn

on the power occasionally to charge it.

19

1 Insert the power cord in the electrical

outlet and turn on the power.

• Press “I” to turn on the power.

• Press “O” to turn off the power.

The folding stoppers and stacker rollers on the

folding plates will move to their initial setting

positions when the power is turned on. Wait

for a few seconds for this to complete which is

indicated by the sound of the buzzer.

2 Raise the paper set lever and place

some paper on the paper feed table.

• Loosen the fixing screws of the guide, and move

the guide slightly more than the width of the paper.

• Loosen the paper and stack sheets of paper neatly

on the paper feed table.

• Insert the paper until its front part touches the front

guide plate lightly.

3 After pressing the guide to the side of

the paper lightly, tighten the screws

to secure the guide.

• The left and right guides move in the same

direction.

Paper can be stacked to a height of

approximately 45 mm at one time. Do not

stack too many sheets paper.

4 Lower the paper set lever.

Start the various fixed folding operations for fixed paper as follows.

no special folding methods have been registered,

the special folding mode cannot be selected and

instead the fixed folding mode will be set.

6 Check the paper size display.

• When paper outside the fixed size is used, the size

of the paper will not be detected automatically and

consequently not displayed.

When using such a kind of paper, refer to

“Using Non-Fixed Paper” on page 44.
