And the width adjuster 50 is driven to move in the direction of the side plate 42; when the width adjuster 50 is moved to the position where the paper 1 is touched, the screw 30 can be moved by the greater resistance of the width adjuster 50. η increases its rotational torque and consumes more power; when the controller 90 detects that the motor π consumes more power, it sends a signal that controls the motor 11 to stop rotating, so that the motor 11 stops rotating. When the 100 is placed on the bottom plate 41, the width adjuster 5〇 can be automatically moved to the clamp. When the motor 11 drives the encoder disc 60 to rotate synchronously, the encoder disc sensor 7〇 can sense the amount of rotation of the encoder disc 60; the controller 90 detects the encoder disc sensing. When the value of the amount of rotation of the code disc 60 is sensed, the width of the paper 100 can be known by comparing with the pre-stored value, and the user can be further reminded that the user is currently placed in the tray 40 by the audio-visual display device. The specification of the paper 100 allows the consumer to avoid the printing operation using the paper 100 which is not the required specification. The present invention also causes the button of the electrical controller 90 to replace the paper sensor 80, and sends a control signal to rotate the motor 11 so that the motor 11 is rotated. The width adjuster 5〇 automatically moves to the position where the paper 100 is clamped. The invention automatically moves the printer to the width of the paper sheet 200918324, and can automatically adjust the paper width of the paper tray, which can be avoided. The manual adjustment error can more accurately control the stability when entering the paper, and can feed back the width value of the paper to the printer, which can further remind the user that the paper to be printed does not match the paper in the tray.
