5. Operating Instructions
This section details the steps for operating your automatic paper folding machine.
5.1 Basic Operation
- Power On: Flip the red power switch to the 'ON' position.
- Load Paper: Place a stack of paper into the input tray, ensuring it is aligned correctly with the guides.
- Set Electronic Counter: Use the electronic counter to set the desired number of sheets to be folded. If you set '0010', the machine will stop after folding 10 sheets. If '0000' is displayed, the machine will not fold.
- Adjust Speed: Turn the speed control dial to set the desired folding speed. Start with a lower speed for testing and adjust as needed.
- Start Folding: Press the 'START' button to begin the folding process.
- Power Off: Once folding is complete or if you need to stop, press the 'STOP' button and then turn off the power switch.

5.2 Adjusting for Different Fold Types
The machine can perform various fold types. Adjustments are made by manipulating the folding plates and rollers.
- Standard Folds: For common folds like single or double folds, adjust the folding plates according to the desired crease lines.
- Cross Fold: To achieve a cross fold, the horizontal crease is formed by adjusting the No. 1 plate. The vertical crease is an indentation. Adjust the position of the two rollers: moving them closer to the middle deepens the vertical indentation, while moving them farther apart makes the indentation disappear.
- Roller Adjustment: The machine is equipped with three soft rollers with gears for smooth feeding. Different rubbing pads can be chosen to adapt to various paper types.

- Cleaning: Regularly clean the paper dust and debris from the input tray, rollers, and output area using a soft, dry cloth or a small brush. Ensure the machine is unplugged before cleaning.
- Roller Inspection: Periodically inspect the rollers for wear or damage. Worn rollers can affect folding quality.
- Lubrication: Refer to the manufacturer's guidelines for any specific lubrication requirements. Generally, moving parts may require light lubrication over time.
- Storage: When not in use for extended periods, store the machine in a clean, dry environment, preferably covered to protect it from dust.
