3. Cross Folding

Cross folding refers to performing the double parallel, letter, or other types of folds for paper already folded using a single fold.

Cross folding can be used when, for example, a sheet of ledger size paper folded using the double parallel fold is still too large to be enclosed in an envelope.

Note: The maximum weight of paper that can be used for cross folding is 28lb. bond. This may vary due to the following conditions:

• Paper type and size
• Direction of grain
• Temperature and relative humidity
• Printing condition

The fold position may be displaced to a greater extent than when using a regular fold method. Also, a corner of the paper may be folded inside as indicated in the figure at right. This does not mean that the machine has malfunctioned.

Note: 1.) Move the paper feed rollers on both sides to proper position in advance so that all of the rollers can feed correctly.

2.) Flatten the crease firmly. Do not stack too many

sheets of paper on the feed table.

3.) Use paper support guide(s) to help hold paper down

(8) Adjustment

(A) Skew Adjustment

If the folding position is slanted it can be adjusted using the skew adjustment knob.

2. Fine Adjustment

Move the stopper using the stopper fine adjustment knob.

Caution: If the fine adjustment knob is moved, when the

TEST key is pressed, the machine will continue to fold, when

the START / STOP key is pressed, the machine will start to

fold after the stopper is returned to the previous position

10. Maintenance

Two rollers can be removed and installed without using any tool, which facilitates cleaning of the rollers and paper ejection photo sensor. As the other two rollers cannot be removed, they should be cleaned while revolving them little by little. Rollers should be moistened with water and wiped off with a cloth wrung tightly. If only one sheet of paper is fed, use a soft cotton swab to remove paper dust, etc. from the face of the paper ejection photo sensor shown by the arrow.

1. Removing the rollers

Remove the upper roller in the order of １ to ３, and then remove the lower roller.

１ Move down the roller setting lever to the OFF

position.

２ Slide the roller to the right. (Its shaft will come off from the left-side hole.)

３ Remove the roller from the right-side hole.

2. Setting of the rollers

In the reverse order of removal, set the lower roller first.

[1] Insert the roller deep to the right.

[2] Slide the roller to the left.

• Be careful not to let the roller shaft on both sides get stuck on Part A.

As shown above, the roller shaft should be placed on Part A.

[3] Move up the roller setting lever to the ON position.

If the roller is not firmly fixed, it may cause operating problems. If it cannot be fixed, contact your dealer.

<Cleaning the paper feed photo sensor>

Sensor position

Open the safety cover and wipe the surface (black plastic) of the paper feed photo sensor with the tip of a cotton swap or similar material moistened in water.

Caution! When cleaning, make sure that no residue from the cotton swab is left in the unit or the paper feed may stop with an error after feeding a single sheet (Check lamp (1) flashes). → See "(11) Troubleshooting, Check lamp (1)" on page 22.

When replacing the paper feed roller and paper separator, proceed in the order (1) → (2).

Brake pad (fixed with dual-sided adhesive tape)

Grasp the paper separator (with plastic part) at both ends and pull it out. To install, reverse the procedure.

To order the parts above, please contact your dealer.

11. Troubleshooting

If Check lamp (1) is flashing it may indicate:

2. Paper jam at paper feed photo sensor
3. Paper feed photo sensor is dirty

If Check lamp (2) is flashing it may indicate:

1. Paper jam at fold tables
2. Plug is disconnected

If Check lamp (3) is flashing it may indicate:

1. Paper jam at paper eject photo sensor
2. Paper eject photo sensor is dirty

Note: If paper is loaded immediately after printing, problems such as jamming, double feed, slipping, and wrinkling may occur. Make sure that the paper is completely dry before loading.

If the unit is placed in the vicinity of a fluorescent lamp that operates irregularly, the paper size detection sensor may not function properly. In such a case, increase the distance between the unit and the fluorescent lamp.

(12) Removing the fold tables

(1) Set the power switch to OFF.

(2) Disconnect the plugs.

(3) Remove the fold tables.

Be sure to always remove plugs prior to removing tables.
