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.

NoteNote

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.

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

NoteNote

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.

7-2. Precautions on Stacking Paper

7. PRECAUTIONS PRIOR TO USE

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

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.

<Paper unaligned on

the left and right sides>

<Paper unaligned at

the lead and trail edges>

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.

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

NoteNote

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 at the top left of the LCD.

7. PRECAUTIONS PRIOR TO USE

7-4. Automatic Rise/Descent of the Paper Feed Tray

When paper is stacked on the paper feed tray, the paper feed guides are set, and the start or test key is pressed, the paper feed tray rises automatically.

When using large or heavy paper, the paper feed tray may not be able to rise due to the weight of the paper. In

NoteNote

such cases, stack less paper.

Paper feed guides

The paper feed tray descends automatically when paper is removed from the paper feed tray. It will also descends automatically when paper runs out on the paper feed tray during a folding operation.

Raising/lowering paper feed tray manually

To raise the paper feed tray, press the “+” key of the folding plate 1 folding stopper adjusting key while pressing the stop key. To lower, press the “–” key.

7-5. 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.

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.

(3) Custom folding

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.

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

NoteNote

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

9. STANDARD FOLDING OF STANDARD PAPER

Standard folding of standard paper is the basic operation of this unit.

9-1. Standard Paper

The standard paper designated by this unit consists of the following five types: LGR, LGL, LTR, STMT, and INV. All of these sizes are valid only when stacked on the paper feed tray in the short edge feeding direction.

The above standard paper may not be usable for

NoteNote

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.

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.

NoteNote

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

14-2. Operation Procedure

Fan the paper well.

NoteNote

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

Stack paper on the paper feed tray after neatly aligning the paper, and set the paper

feed guides.

For precautions on paper, refer to “7. PRECAUTIONS PRIOR TO USE” (☞p.18).

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

NoteNote

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.

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

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

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.

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

NoteNote

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.

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.

“9. STANDARD FOLDING OF STANDARD PAPER” (☞p.22)

eSee

15. USING SPECIAL PAPER

15-1. Double Folding Thick 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.

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

NoteNote

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

Thick paper mode

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)

NoteNote

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.

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

NoteNote

lighting.

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.

“11. STANDARD FOLDING OF NON-STANDARD PAPER” (☞p.32)

eSee

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.

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

NoteNote

light, and is not a malfunction.

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

17-1. Interval Function

The interval function suspends paper folding operations for a certain period of time after every specified number of sheets, and sorts the folded paper. This allows the ejected paper to be removed, and preparations made for distributing folded paper, placing paper in envelopes during the suspended time. For example, if there is a need to bind the folded paper in sets of 50 sheets, the unit can be set to suspend folding operations for the certain period of time for every 50 sheets.

Feed Inlet Sensor

The paper feed inlet of this unit has a sensor for checking the paper feed state. This sensor may fail with the error message “JAM FEED SECT” when printing powder and paper dust accumulate on it.

When this message appears, clean the sensor with an Air Duster (a commercially available air spray for eliminating dust for office equipment).

Open the top cover.

Insert the nozzle of the Air Duster into

the hole of the sensor cover and paper feed inlet, and spray briefly.

NoteNote

Use a non-flammable type. Read the instructions on use carefully, and be sure to observe them. The Air Duster gas will cool the sensor and metallic parts, causing temporary condensation. After cleaning, leave for about five minutes before use.
