Chapter 1 Before Operation

Handling Paper

Paper used

• Make sure that the printing ink on the paper has dried completely prior to use.
• Wet ink or ink that is not completely dried may stain the folding roller causing trouble such as smearing on paper.
• Use of paper printed with special types of ink may cause the folding roller to swell or deform, and folding misalignment may occur.

Paper may not be fed smoothly into the folding plate or deformed folding may occur depending on different environmental factors (temperature, humidity), paper ream weight, paper type, paper grain direction if curled paper is used. Make sure to flatten curled paper or paper with folded lines before use. Separate the sheets of paper well before stacking them.

Precautions on stacking paper

Do not stack the sheets of paper on the paper feed tray with the sides of sheets unaligned or some sheets protruding from the stack. This machine has an automatic standard paper size detection function. It automatically detects paper size at the paper feed guides. Therefore, if paper is protruding out from the left or right side, it is unable to detect paper size accurately and may determine standard paper as non-standard. (DF-980)

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

Do not stack paper on the paper feed tray with the lead and trail edges unaligned or some sheets protruding out.

Processing with sheets unaligned on the lead and trail edges may lead to unstable feed causing such trouble as miss-feed and double-feed.

Chapter 3 Advanced Operation

Cross fold paper at the desired folding position

Cross fold is a method to cross-fold standard or non-standard paper at arbitrary positions. Standard paper or non-standard paper is handled in the same way and cross-folded by using a method to register the folding position as a custom folding.

Register custom folding referring to the procedures of “3. Custom Folding” (p.3-8).

Single-fold the paper in the custom folding mode.

Register the single-folded paper again as custom folding referring to the procedures of “3. Custom Folding” (p.3-8).

Take procedures for “4-1-1. Stacking paper” step 2~ “4-1-2. Adjustment of the parts”, and “4-1-3. Operation procedures” of “4-1. Cross fold of standard paper” (p.3-13).

Using Special Paper

Art paper, coated paper

Do not put fingers inside during operation. Keep away long hair, ties, jewelry and loose clothing.

It could cause injury.

Art paper and coated paper often stick to each other due to the printing ink and become difficult to separate, resulting in double-feed. When using these types of paper, follow the procedure below.

Some of recycled art or coated paper may be unsuitable for folding due to weak stiffness.

Chapter 3 Advanced Operation

Stack the paper on the paper feed tray.

Attach the paper feed guide.

Do not stack too many sheets of paper on the paper feed tray. If too many sheets are stacked, the paper will stick on each other from its height and become difficult to separate, resulting in double-feed. The amount of stacked sheets should be about half the weight of the paper feed guide (approx. 25 mm/0.98 inch).

25 mm 0.98 inch

Set the feeding pressure adjustment lever to [3].

• Set the paper feed pressure within the [3] to [5] range on the scale.
• If the paper slips and mis-feed occurs, increase the paper feed pressure to [4] or [5].

Set the separating pressure adjustment dial to [2.5].

If double-feed occurs, increase the separating pressure by [0.5] at a time.

Press the test key to test fold.

If abnormal folding occurs, decrease the processing speed.

After completing folding operation of art paper or coated paper, return the paper feeding pressure and separating pressure each to [0]. If fine quality paper is used with the paper feed pressure and separating pressure set to the values for art paper and coated paper, double-feed may occur, or leading edge of paper may be damaged.

Chapter 3 Advanced Operation

Rough paper, recycled paper

Some recycled paper may be thin, flimsy and easy to curl when copied, and therefore inappropriate for folding. When folding such paper, pay attention to the following points.

• Separate paper well prior to stacking on the paper feed tray.
• Set the processing speed as low as possible. If set to high, wrinkles or deformed folding will result.
• Set the paper feed pressure as low as possible. If set to high, double-feed will result.
• Set the paper separating pressure as low as possible. If set to high, the center of the lead edge of the paper may be scratched or turned over.

B7, A7, A6 size paper

B7, A7, A6 size paper (fed by short edge feeding) can be folded in the following conditions. However, B7, A7, or A6 paper is regarded as non-standard paper, and the paper length should be registered, referring to “2. Standard Folding of Non-Standard Paper” (p.3-7).

• Folding mode (When the [Folding Mode] key is pressed, the display lamp of the folding mode which cannot be selected will not light up). B7 : Single fold, Gate fold A7 : Single fold A6 : Single fold, Letter fold, Accordion-fold, Gate fold
• Thickness 64 to 81.4 g/m 2 /16 to 22 lb
• Stacking height 35 mm/1.37 inches or less
• Feeding pressure [0] or [-1]
• Separating pressure [0]
• Process Speed [1] to [4]

If small and light paper is used, too fast processing speed will result in stream-feed (continuous feed). Decrease the processing speed as slow as possible.

When mis-feed or double-feed occurs even though the feeding pressure and separating pressure are set to the set value, adjust the feeding pressure and separating pressure. (p.2-6)

Chapter 3 Advanced Operation

Changing the Stacker Roller Height

Some thick and stiff paper may not be ejected smoothly because the paper may open after folding. Change the stacker roller height and widen the space for the paper to pass in ejection.

Remove the auxiliary paper ejection guide.

Lift the stacker roller and hold it with hand to move to the [A] position shown in the figure.

After completing folding operations, be sure to return the stacker roller to the standard position. Leaving it in the raised state will result in poor alignment of ejected paper.
