Cassette lift operation (PD) The lift-up operation keeps the stack surface of media in the paper deck at a specified position to perform stable pickup operation. The paper deck driver drives the PD lifter motor (M1700) to move up the lifter plate in which media is stacked. The PD lifter motor uses four pulleys to wind the wire cables and two wire cables lift the lifter plate. When the PD front door is opened, the pulley gears and the motor gear are disengaged and the lifter plate lowers under its own weight.
The paper deck driver monitors the PD media stack surface sensors (PS1701, PS1702) when the product is turned on, when the PD front door is closed or during a print operation to perform the lift-up operation. Lift operation (PD) 1. Initial lift-up operation The initial lift-up operation is performed if either one of the PD media stack surface sensors (PS1701,PS1702) does not detect the media surface when the power is turned on or when the PD front door is closed. The paper deck driver drives the PD lifter motor for a specified period after both of the PD media stack surface sensors detect media and lifts the stack surface to the pickup position.
The paper deck driver determines a paper deck lifter motor failure and notifies the DC controller if both of the PD media stack surface sensors do not detect media within a specified period from when a lift-up operation is started. 2. During print lift-up operation The during print lift-up operation is performed when the media surface is lowered for a specified level due to a pickup operation.
