5. Handling Paper

5-1. Paper used

• Make sure that the printing ink on the paper has dried completely prior to use.

• If used without the ink completely dried, the folding roller or paper may become dirty.

• Paper printed with special ink may cause the swelling and deformation of the rubber rolls, leading to folding misalignment.

• If curled paper is used, depending on the environmental condition (temperature, humidity), paper quantity, paper type, and paper fiber, it may not flow smoothly into the folding plate or may not be folded properly. Flatten the paper prior to use.

• When folding B6 size paper or less, if you use fine quality paper of 64 g/m 2 may not be able to be ejected. (EU)

/17.1 lb or thicker, the paper

• Fan paper well prior to use.

5-2. Precautions on stacking paper

[a] Do not stack paper on the paper feed tray with the left and right sides of the paper unaligned or some sheets protruding out.

[b] Do not stack paper on the paper feed tray with the lead and tail edges unaligned or some sheets protruding out.

• Processing with sheets unaligned on the right or left side may cause such trouble as folding misalignment and jamming.

• If the paper is protruding at the lead or tail edge, paper will not be fed stably, resulting in problems such as paper feed error and folding misalignment.

[a]

[b]

Chapter 1 Before Operation

• When stacking just a few sheets of paper on the paper feed tray, lower the paper set lever while pressing the lead edge of the paper against the guide plate.

5. Using Specific Paper

Do not put fingers inside during operation.

Keep away long hair, ties, jewelry and loose clothing.

It could cause injury.

5-1. Art paper, coated paper

• By their specifications, art paper or coated paper use print ink, etc., to adhere to paper, becoming difficult to peel off, and easier for two sheet feeds to occur. When using art paper or coated paper, observe the following procedures to perform the operations.

• Art paper or coated paper that are made of recycled paper may lack of stiffness, and may not be suitable for processing.

• The recommended ream weight is 104.7 to 127.9 g/m 2 /27.8 to 33.9 lb. Depending on the usage environment or other conditions, the processing may not go very well.

Carefully separate the paper.

Art paper and coated paper adhere more easily than copy paper or other fine quality paper, and carefully separate them.

Arrange the paper.

Stack paper in the paper feed tray.

Chapter 2 “2-3. Stacking paper” (p.19)

Keep the volume of paper stacked in the paper feed tray to a minimum.

A general guide is about half the height (about 25 mm/0.98 inch) of the paper feed guides. If the volume of paper is too large, the weight will cause the paper to adhere together, making peeling off difficult, and occurrence of two sheet feeds.

Perform the operations in Chapter 2 “3-1. Selecting paper size” (p.20) to “3-8. Performing folding operation” (p.26).

• Paper feed pressure adjustment lever

DF-870: Set to [3].

If paper mis-feed has occurred, raise the paper feed pressure to [4] or [5].

DF-850: Set to (thick paper).

• Separation pressure adjustment dial (DF-870 only)

Set to [2.5].

When two-sheet feed has occurred, raise the separation pressure by [0.5] scale points at a time.

Chapter 3 Advanced Operation

• If paper mis-feed still occurs even after the paper feed pressure and separation pressure are adjusted, set the [Feed Time] to [Long].

After the operations are ended, restore the paper feed pressure and separation pressure.

If copy paper or fine quality paper is used in the setting of art paper or coated paper, the strong paper feed pressure could cause two-sheet feeds, while the strong separation pressure could cause damage to the front edges of the paper.

Return the auxiliary paper feed ring to its original position.

If the [Feed Time] is changed, return the setting to [Mid].

5-2. Rough paper, recycled paper

Rough paper and recycled paper are thin paper lacking stiffness. Perform processing with caution for the following points.

• Before stacking in the paper feed tray, carefully separate the paper.

• Set the processing speed to low.

If the processing speed is high, it could result in paper wrinkling or abnormal folding.

• Set the paper feed pressure to low.

If the paper feed pressure is high, it could result in two-sheet feeds.

5-3. B7, A6 size paper (For EU)

The B7, A6 size paper can be processed under the following conditions.

Paper stacking orientation: Vertical stacking

Folding form: Single fold

There are limits to the folding form depending on paper quality and paper size.

If paper is small and light, a high processing speed could result in chaining (hooked feeds). Keep the processing speed as low as possible.

6. Adjusting Misalignment

Folding misalignment consists of two types, "up/down direction misalignment" and "left/right direction misalignment." Moreover, in addition to that, factors such as paper characteristics, etc., can also lead to

"abnormal folding."

Misalignment of the folding position can occur, based on the usage environment (temperature, humidity), paper quality, paper thickness, paper grain direction (vertical, horizontal), cutting precision, and print condition, etc.

Chapter 3 Advanced Operation

6-1. Correcting folding misalignment along vertical length of paper

If the folding position is misaligned in the up/down direction, use of the following method to change the folding stopper position, and perform fine adjustment of the folding dimension, can correct the misalignment.

DF-870

The folding stopper fine adjustment position cannot be registered. If the paper size and folding mode has been reset, or the power switch has been turned off, the folding stopper is automatically returned to the setting position.

Perform the adjustment again.

7. Function Settings

Function settings can adjust in support of operating procedures or various paper types, according to use.

7-1. Operation modes

Operation mode refers to setting operations for the stoppers for the folding plate 1 and folding plate 2 when the power is first turned on.

[STD] (Standard)

[LF] (Last fold mode)

Function for starting up in the normal setting condition when the power is turned on.

Function for starting up using the setting last used on the machine the previous time.

If the power is turned off during paper folding operation, the setting information is not stored.

[SF](Stopper fixed mode) Function for omitting the operations panel setting when always processing using the same conditions.

The machine is constantly set automatically using the same conditions.

When the power is turned on, the initial operation is no longer performed.

Because automatic setting is performed under the same conditions, the paper size and folding mode cannot be changed.

Folding misalignment in the up or down direction will occur if the power is turned on after turned off during operation of the folding stopper or during temporary stop caused by opening the cover. In this case, be sure to press the C key while pressing the

key to forcibly eject paper when you turn on the power.

If the sheet number set by the subtraction counter differs from the sheet number set in the interval, the sheet number set by the subtraction counter takes priority.

For example, if the interval is set to 20 sheets and the subtraction counter to 50 sheets, the 20 sheets will be set in 2 set processing (total of 40 sheets process completed), followed by the start of the third set, but the machine stops after 10 sheets process completed because the subtraction counter is functioning. If the key is pressed after the machine shutdown, the remaining 10 sheets process is ended, and an interval is entered.
