How to Use: Max EH-70F Electronic Stapler Instruction Manual

Overview

The EH-70F Electronic Stapler is a heavy-duty desktop stapling machine designed for offices, print rooms, copy centers, schools, and other workplaces that regularly staple document sets. Its motor-driven mechanism handles 2 to 70 sheets of suitable paper at approximately two staples per second, while automatic and manual modes help position staples accurately.

The EH-70F Electronic Stapler uses a replaceable MAX No. 70FE staple cartridge and supports adjustable stapling depth for standard, edge, and corner applications. A flat-clinch stapling action helps finished documents stack neatly.

Detailed Description

The stapler uses a motor-driven link mechanism to move staples through the paper stack. The automatic feed system advances the next staple into position after each operation, allowing repeated stapling without manually loading individual staples.

The case cap covers the cartridge and stapling mechanism. The selector switch chooses automatic or manual operation, while the LED lamp indicates the machine status. The paper table supports sheets during manual stapling, and the manual button activates a staple when the selector is set to Manual.

A center-position mark on the front helps align documents for horizontal stapling. The depth-control slider changes how far the paper enters the stapling area. A green lever and opener handle provide access for removing jammed staples.

Safety

Electrical and operating precautions

• Read and retain the instruction manual before using the machine.
• Use only the supplied AC adapter rated for AC 100–240 V, 50–60 Hz.
• Connect the adapter directly to a suitable wall outlet. Do not overload one outlet with multiple high-power appliances.
• Never connect or disconnect the power plug with wet hands.
• Keep the power cord free from heavy objects, and disconnect the plug by holding the plug rather than pulling the cord.
• Do not operate the stapler if it smokes, produces an unusual sound, or gives off an abnormal odor. Disconnect it immediately and arrange qualified servicing.
• Disconnect power immediately if water enters the machine.
• Do not disassemble or modify the stapler.
• Never insert fingers, pens, wires, or other foreign objects into the machine.
• Never touch the white switch by hand. The mechanism may activate unexpectedly.
• Keep fingers away from the stapling area during operation.
• Disconnect the power cord before loading or replacing a cartridge and before clearing a jam.

Installation and handling

• Use the machine indoors in a dry location.
• Place it on a stable, level surface away from vibration.
• Keep the stapler away from direct sunlight, heat sources, dust, and excessive humidity.
• Do not use or store it where temperatures fall below 0°C (32°F) or rise above 40°C (104°F).
• Do not place paper, cloth, or heavy items on the machine or power cord.
• Disconnect the power plug before moving or storing the stapler for an extended period.
• Do not share the outlet with high-capacity equipment such as air conditioners, refrigerators, microwaves, or office machinery that can cause voltage drops.

Staple and cartridge precautions

• Use only MAX No. 70FE staple cartridges.
• Keep cartridges away from children. A swallowed staple requires prompt medical attention.
• Do not reuse broken or shortened staples.
• Do not touch the staple sensor or feeding roller while removing staples.
• The motor can become hot after stapling. Avoid touching it during cartridge replacement.
• Wash skin promptly with soap and water if cartridge grease gets on your hands or body.
• The case cap must be fully closed before stapling. The safety mechanism prevents operation while it is open.

Setup and Operation

Loading the staple cartridge

1. Disconnect the power cord from the wall outlet.
2. Prepare the MAX No. 70FE cartridge. Pull off the stopper beneath the cartridge in the indicated direction.
3. Check the cartridge. If part of the staple sheet protrudes, push it back inside to help prevent a jam.
4. Open the case cap.
5. Insert the cartridge in the direction shown by the machine’s guide.
6. Close the case cap securely.
7. Reconnect the power cord.

Automatic stapling

1. Move the selector switch to Auto.
2. Adjust the stapling depth by loosening the depth-control knob and sliding the control between approximately 6 and 18 mm.
3. Turn the knob to the LOCK position after adjustment. Leaving it unlocked may interfere with the sensor or damage the mechanism.
4. Use the center-position mark on the front as a horizontal alignment reference.
5. Move the document left or right to choose the desired staple location.
6. Insert the paper into the stapling opening. The machine detects the paper and staples automatically.

Manual stapling

1. Move the selector switch to Manual.
2. Pull the paper table toward you.
3. Insert the document into the desired position.
4. Press the manual button to activate the stapler.

Manual mode is particularly useful when the staple must be placed close to the edge. The manual depth range is approximately 3 to 18 mm.

Corner stapling

1. Position the corner of the document in the stapling area.
2. For an automatic depth setting of 6 mm, the staple location is approximately 12 mm from the paper edge.

During the first use, the machine may make approximately five to seven idle strokes before stapling a document. This is a normal staple-feeding operation.

LED indicators

• Green: The stapler is ready to activate.
• Red: The cartridge has no usable staples remaining and should be replaced. Paper will not be stapled while this condition is present.

Cleaning and Maintenance

• Clean dirt from the housing with a dry cloth.
• Do not use alcohol, benzene, thinner, other solvents, or a damp cloth.
• Clean the power plug regularly to prevent dust accumulation and reduce fire risk.
• Allow the motor to cool if the stapler has been operating continuously for a long time. If it stops stapling because the motor is hot, stop operation for at least 30 minutes before trying again.
• Use fewer than 70 sheets per operation. Do not force the machine to staple thicker stacks or paper types outside its intended specification.
• Disconnect the power plug when the stapler will remain unused for a long period.

Troubleshooting

The stapler does not activate

• Confirm that the case cap is completely closed.
• Check whether the selector switch is set to the intended mode.
• In automatic mode, ensure that the paper is positioned in the sensing area.
• Check the LED. A red light indicates that the staple cartridge needs replacement.
• Confirm that the power cord and AC adapter are connected correctly.

The machine becomes hot or stops stapling

Continuous operation can heat the motor enough to prevent stapling. Stop using the machine for 30 minutes or longer so it can cool, then resume operation.

Clearing a jammed staple

1. Disconnect the power cord from the outlet.
2. Open the case cap.
3. Hold the cartridge and pull it upward to remove it.
4. Press inward on the green lever at the front of the machine.
5. While holding the lever, pull up the opener handle.
6. Remove the jammed staple carefully.
7. Push the opener handle back down to its original position.
8. Inspect the cartridge. If the staple sheet is exposed, push it back into the cartridge before reinstalling it.

If the machine remains out of order after these steps, do not continue operating it. Have it inspected by an appropriately qualified service provider.
