7. PRECAUTIONS PRIOR TO USE

The following explains precautions to be understood prior to using this unit.

7-1. Paper Used

If using folded or curled paper, flatten first prior to use.

Note Always pile up paper when storing. Also do not store paper in humid places.

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

Otherwise, the ink will dirty the paper feed ring and folding roller, and this will not only lead to reduced folding performance, but the ink will also adhere to and dirty the folded paper.

Use paper that has been cut at right angles.

Otherwise, problems such as folding misalignment will result.

Fan paper just copied or printed well prior to use.

Paper just copied or printed contains considerable static electricity, and if not fanned well, problems such as double-feed will result.

Note In some cases, paper may not be fed smoothly into the folding plate due to the environment (temperature,

humidity), paper thickness, paper type, paper grain direction, paper states (curled, etc.), and processing speed, etc., and as a result, the paper may not be folded properly. In such cases, lower the processing speed, or improve the paper states (curled, etc.) before use.

7. PRECAUTIONS PRIOR TO USE

7-2. Precautions on Stacking Paper

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

<Paper unaligned on the left and right sides>

<Paper unaligned at the lead and trail edges>

This unit 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. It may also result in problems such as paper feed errors and folding misalignment, etc. Be sure to align paper neatly when stacking.

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

This will result in unstable paper feed, and result in problems such as paper feed errors and folding misalignment, etc. Be sure to align paper neatly when stacking.

7-3. Automatic Detection of Paper Size

Five standard paper sizes can automatically be detected by this unit: LGR, LGL, LTR, STMT, and INV. For paper to be automatically detected, paper must be set in the short edge feeding direction.

Note For some paper, stacking paper on the paper feed tray in the long edge feeding direction will result in paper

size detection error. (For example, if LTR paper is stacked in the long edge feeding direction on the paper feed tray, it will be detected as LGR size.)

When paper is stacked on the paper feed tray according to the corresponding paper size on the tray scale, and the paper feed guides are secured at the scale position, the paper size is automatically detected. The detectable range is within ±0.28".

When paper size is detected, it will be displayed on the left window.

7. PRECAUTIONS PRIOR TO USE

7-4. Checking the Front/Back, Top/End of Paper

Check how the paper was placed on the paper feed tray (front/back, top/end), because this will affect the folding misalignment which may occur.

<Example> When paper with a white front and black back is finished in the following folding modes

7-5. Using the “QUICK START”

The QUICK START at the end of this manual outlines the most common paper folding procedure standard folding of standard paper to facilitate use of this unit, after having read this instruction manual once.

Use it as follows.

Enlarge pages 1/2 and 2/2 of the QUICK START on a copy machine, and paste them on the wall in front of the unit for reference when operating this unit.

Copy pages 1/2 and 2/2 in the same size, and place them in a plastic file for reference when operating this unit.

Note When adding comments or changing the contents of the QUICK START, give consideration to safety.

8. PAPER FOLDING METHODS

The paper folding methods of this unit can broadly be divided into the following three types.

1. Standard folding of standard paper

This is the basic paper folding operation of this unit. With this method, the “standard paper” designated by this unit is set to the standard folding mode displayed on the control panel and paper folding is performed.

2. Standard folding of non-standard paper (folding by entering paper length)

With this method, the length of paper other than the standard paper designated by this unit (this is called “nonstandard paper”) is registered, this paper is set to the standard folding mode displayed on the control panel, and paper folding is performed. The length of the paper registered is calculated to match the standard folding mode, and the positions (folding positions) of the folding stoppers of the folding plates are automatically set.

Set the positions (folding positions) of the folding stoppers of folding plates 1 and 2 manually. As the stopper position (folding position) can be specified, it allows non-standard folding to be performed freely.

Note There are certain restrictions (unfoldable areas) according to the paper length, folding plate length, etc. for the

above methods. For specific details of folding methods and restrictions, refer to the following chapters on folding methods.

10. FOLDING MISALIGNMENT

Depending on the paper type, thickness, printing state, processing speed, etc., paper of the same size may be folded differently and folding misalignment may occur. Folding misalignment consists of two types; “folding misalignment along the sides of the paper” and “folding misalignment along the vertical length of the paper”. Other than this, “deformed folding” may also occur due to paper characteristics, etc.

The following describes how to correct folding misalignments and deformed folding.

10-1. Correcting Folding Misalignment Along Sides of Paper

When the folded paper is misaligned along the sides as shown in the figure due to slight misalignment when the paper was trimmed, paper printing state, dirty folding roller, etc., correct using the skew correction knob of the paper feed tray.

10-2. Correcting Folding Misalignment Along Vertical Length of Paper

When the folded paper is misaligned along the vertical length as shown in the figure due to the paper thickness, type, printing state, etc., adjust the positions of the folding stoppers of folding plates 1 and 2 to correct the misalignment.

<Example of folding misalignment along vertical length of paper>

Adjust the positions of the folding stoppers using the folding stopper adjusting keys of folding plates 1 and 2 on the control panel. Pressing the “+” key moves the folding stoppers of folding plates 1 and 2 in the A direction of the figure. Pressing the “–” key moves in the B direction of the figure. Each press moves the folding stopper by 0.005". (One folding stopper is provided inside folding plates 1 and 2 respectively. Folding stoppers cannot be seen from outside.)

The value corrected using the folding stopper adjusting key is displayed on the right window. The left window displays “F1” when corrected using the folding plate 1 adjusting key and “F2” when corrected using the folding plate 2 adjusting key.

Note Corrected values cannot be registered in the standard folding of non-standard paper. To register the folding

stopper position, use the custom folding registration function.

10. FOLDING MISALIGNMENT

Correction by the “+” key Within +0.2"

For standard folding, the adjustable range using the folding stopper adjusting key is within ±0.2" from the center of the paper.

If set exceeding ±0.2", the buzzer sounds

“pi.pi.pi”, and the folding stoppers will stop at the ±0.2" position of the adjustable range.

Correction by the “–” key Within –0.2"

The positions of the folding stoppers of folding plates 1 and 2 may not be adjustable to ±0.2" according to the length of the paper used. This restriction is due to the length of the paper and length of folding plates 1 and 2. The restricted folding plate and correction details differ according to the folding mode and paper length. Refer to the following table.

10-3. Correcting Deformed Folding

The paper fed to the folding plates may be folded without reaching the folding stoppers inside the folding plates due to the using environment (temperature, humidity), paper thickness, paper type, paper grain direction, paper state such as curling, processing speed, etc., resulting in deformed folding. If this occurs, check the following.

<Example of deformed folding>

1. Is appropriate paper within the specifications used?

Do not use paper outside the specifications. Particularly, deformed folding occurs frequently in the use of thin, flimsy paper not appropriate for the paper folder.

See e “21. SPECIFICATIONS” ( ☞ p.59)

2. Is the processing speed too fast?

Lower the processing speed when deformed folding occurs for thin and flimsy paper.

3. Was the paper fanned appropriately prior to stacking on the paper feed tray?

Fan paper well prior to stacking.

4. Is the paper stacked correctly on the paper feed tray?

Stack paper on the paper feed tray after aligning well, and set the paper feed guides at the correct positions. Also tighten the fixing screws of the paper feed guides firmly.

11. STANDARD FOLDING OF NON-STANDARD PAPER

Standard folding of non-standard paper is the process of registering the length of non-standard paper, setting the paper to a standard folding mode (six types) displayed on the control panel.

Paper other than the five standard paper specified by this unit LGR, LGL, LTR, STMT, and INV are called non-standard paper.

Note Standard paper size is the size of the paper stacked on the paper feed tray in the short edge feeding direction.

Standard paper which is stacked on the paper feed tray in the long edge feeding direction is considered nonstandard paper.

Six standard folding modes are available as shown below.

13. CROSS FOLDING

Cross folding is folding single-folded paper another time as shown in the figure. Many cross folding styles are available according to settings.

13-2. Precautions on Cross Folding

Pay attention to the following in cross folding.

The maximum thickness of paper used is 28 lb.

The maximum thickness depends on conditions such as using environment (temperature, humidity), paper size, paper type, paper grain direction, paper printing state, etc.

Press along the folded line of singlefolded paper with the fingers.

If the folded line is not folded properly, paper feed will be unstable.

13-1. Cross Folding Methods

The following three cross folding methods are available on this unit.

1. Cross folding of standard paper

Standard paper consists of five types LGR, LGL, LTR, STMT, and INV (short edge feeding of paper) and is paper whose size can be automatically detected.

2. Cross folding of non-standard paper

14. USING ART PAPER AND COATED PAPER

14-1. Characteristics of Art Paper and Coated Paper

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.

Note Some recycled art paper and coated paper may be flimsy and inappropriate for folding.

14-2. Operation Procedure

1 Fan the paper well.

Note Art paper and coated paper need to be fanned well compared to fine quality paper such as copy paper.

For precautions on paper, refer to “7. PRECAUTIONS PRIOR TO USE” (

Note Do not stack too many sheets of paper on the paper feed tray, the amount of which should be about half the

height of the paper feed guide (approx. 1.0"). If too many sheets are stacked, the paper will stick to each other from its weight and become difficult to separate, resulting in double-feed.

3 Set the paper feed pressure adjusting lever to “3”.

Set the paper feed pressure within the “3” to “5” range on the scale. If paper slips and mis-feed occurs, increase the paper feed pressure to “4” or “5”. Paper feed pressure increases as the scale value increases.

the top cover, and set the separating pressure adjusting dial to “2.5”. 4 Open After setting, close the top cover.

If double-feed occurs, increase the paper separating pressure by 0.5 at a time. Paper separating pressure increases as the scale value increases.

Note Do not use fine quality paper such as copy paper with the paper feed pressure and paper separating

pressure settings for art paper and coated paper. Due to the high paper feed pressure, double-feed occurs more easily. In addition, due to the high paper separating pressure, the paper may be damaged at the lead edge. When using fine quality paper, always return to paper feed pressure and paper separating pressure settings to levels suitable for fine quality paper.

5 Press the test key to perform test folding, and check the finish.

If deformed folding occurs, the paper may not have reached the folding plate folding stopper. One solution is to lower the processing speed.

Other steps are the same as standard folding of standard paper.

When double folding fine quality paper larger than 10" in width and thicker than 28 lb, the stiffness of the paper makes it difficult for it to enter between the two folding rollers. For such paper, set the thick paper mode.

Note This mode is intended only for thick paper. Do not use it for folding other types of paper.

Use of this mode results in unstable paper feed, and quickens wear of parts such as the paper feed ring.

In this mode, the folding rollers rotate quickly to help paper enter between the folding rollers.

Setting the thick paper mode

Press the “+” speed key and set the maximum processing speed, and press it again for another two seconds. The maximum speed lamp blinks, indicating that the thick paper mode has been set.

Clearing the thick paper mode

Press the “–” speed key. The maximum speed lamp stops blinking and lights up, indicating that the thick paper mode has been cleared. This setting will also be cleared when the power is turned off.

Blinking (Thick paper mode)

Note This function may not be that effective, depending on the paper thickness and stiffness.

15-2. Using 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.

Fan 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.

15. USING SPECIAL PAPER

15-3. Folding Small Size Paper

Paper size ranges within 5.1" to 7.1" in length and 3.0" to 5.0" in width (fed by short edge feeding) can be folded in the following conditions.

Paper size ranges within 5.1" to 5.5" in length and 3.0" to 4.2" in width can only be single folded or brochure folded. Paper size ranges within 5.6" to 7.1" in length and 4.3" to 5.0" in width can be single folded, letter folded, accordion folded, and brochure folded, but not double folded and irregular accordion folded.

Note When the folding mode key is pressed, the lamps of unselectable folding modes will be skipped without

Paper within the above size ranges are non-standard paper. As the automatic paper size detection function does not work for these paper sizes, there is a need to register the paper length.

See e “11. STANDARD FOLDING OF NON-STANDARD PAPER” ( ☞ p.35)

The thickness of paper which can be used ranges from 16 to 20 lb.

Stack paper on the paper feed tray after fanning it well. However, stack less than usual, within a stacking height of 1.4".

Do not set the maximum processing speed. Set as low as possible.

Note Continuous-feed occurs easily when high processing speeds are set. This is because the paper is small and

light, and is not a malfunction.

Set the paper feed pressure to “0” or “–1”.

Set the paper separating pressure to “0”, and increase the value by 0.5 at a time according to the paper feed conditions.

16-2. Changing the Stacker Roller Height

Some thick and stiff paper may not be ejected smoothly because they may open up after folding. If this happens, change the height of the stacker roller and widen the space for the paper to pass in ejection.

Lift the stacker roller and hold it with subsupport.

Note 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.
