Matters needing attention in using a4 paper
When loading paper, please press the fixed handle of the paper dragging gear box first, then adjust the width of the paper dragging gear box according to the width of the paper and move it to the appropriate position. Open the paper dragging tooth cover, insert the four holes in the front of the computer paper into the teeth of the paper dragging tooth, then close the tooth box and move the paper dragging tooth box to flatten and lock the paper.
When placing computer paper, be sure to pay attention to whether the paper feeding position is appropriate and whether it is aligned parallel to the tractor. After the paper is loaded into the tractor, it should be flat, so as to ensure that the edge of the first paper is clean and flat, and the paper feed is smooth, so as to avoid being stuck in the tractor or the paper feed slot.
