Why does paper wrinkle in Duplo DF-915 Folding Machines?
Paper wrinkles may occur in Duplo Folding Machines if the press pressure of the folding roller is too strong. Adjust the press pressure, especially setting the press pressure of folding roller 1 weak, around 45 to 46 mm (1.77" to 1.81"). Another cause can be a deformed folding roller, in which case you should replace it.
How to fix skewed paper conveyance in Duplo DF-915?
If paper is conveyed skewed, it could be due to several reasons. * The left and right nip amount differs between the folding rollers, check the attached state of the reference stopper, and make the roller nip the same. * The thrust play of the folding roller drive gear is large. Adjust so that there is no thrust play. * The press pressure of the folding roller is not balanced between the left and right sides. Adjust the press pressure. * The folding roller is deformed, in which case replace the folding roller.
What to do if stacker belt rotates heavily on Duplo DF-915?
If the stacker belt rotates heavily, the thrust play of the paper ejection drive shaft and paper ejection clutch may not be appropriate. Adjust it so that the thrust play is less than 0.1 mm (0.004”).
Why are there abnormal metal sliding sounds during rotation of folding rollers in Duplo DF-915?

As a last resort, turn off the power and re-insert the control cord into the connector.
How to correct folding misalignment along the sides of the paper in Duplo Folding Machines?
To correct folding misalignment along the sides of the paper in your Duplo folding machine, try reducing the amount of paper. Ensure the paper feed guides are set correctly and tighten the fixing screws properly. You can also use the skew correction knob to correct the folding misalignment.
What to do if continuous-feeding occurs with small paper in Duplo Folding Machines?
If continuous-feeding occurs with small paper in your Duplo folding machine, ensure you are using paper that meets the specifications. Decrease the paper feed pressure. Adjust the paper feed guides firmly to the paper, ensuring no gaps. Align the paper well before stacking it on the paper feed tray and lower the processing speed.
What to do if paper is not folded at the normal folding position in Duplo Folding Machines?
If paper is not being folded at the normal folding position in your Duplo folding machine, try resetting folding plates 1 and 2. Lower the processing speed, fan the paper well, and humidify the area with a humidifier if needed.
How to resolve folding misalignment along the vertical length of the paper in Duplo Folding Machines?
To resolve folding misalignment along the vertical length of the paper in your Duplo folding machine, return to the speed before the change. When changing the speed, the folding stopper positions of folding plates 1 and 2 must be adjusted. Use the paper you were using before the change. When changing paper, the folding stopper positions of folding plates 1 and 2 must be adjusted.
