摘要:
A former roller, which is driven for rotation, is located at the intake of a former for a folding unit. A controller unit is utilized to control the rotation of the motor, which drives the former roller, in such a way that the former roller exerts a tensile force on a material web that is fed to the former roller.

A system and method for correcting position of a pusher member after power loss to a motor controlling the pusher includes a pusher transport having at least one pusher member mounted to belt and a controller for controlling the pusher transport. A motor is coupled to the belt for controlling the movement of the pusher transport. The motor is driven by a driver coupled to the controller. An encoder is coupled to a shaft of the motor and operatively coupled to the controller, wherein the controller is programmed for using encoder counts representing pusher member position at power loss and at power restored to determine whether the pusher member is past or before an expected position at power loss. The controller is also programmed for determining the distance and direction the pusher member must move to be at the expected position, the controller causing the driver to drive the motor at a specific motor profile to move the pusher member to the expected position.

A sheet stacking apparatus for performing post-processing on sheets received from an image forming apparatus and discharging the processed sheets. A stacking tray has the received sheets stacked thereon. A CPU controls a tray lifting/lowering motor to drive the stacking tray to be lifted or lowered. The CPU determines a vertically moving state of the stacking tray. When the stacking tray is not lowered though the tray lifting/lowering motor is controlled to lower the stacking tray, the CPU notifies the image forming apparatus that a job should be suspended. After notifying, the CPU controls the tray lifting/lowering motor to lift the stacking tray. Then, when the stacking tray can be lifted, the CPU notifies the image forming apparatus that the job is to be resumed.

A translatable media height sensor assembly for measuring a media stack in an imaging forming device. The assembly includes a support and drive and insertion assemblies mounted thereon. Insertion assembly includes a translatable plunger having mounted thereon a sensor and a translatable probe. At a home position, the sensor is actuated by a flag on the support placing sensor output in a first state. During measurement, drive assembly translates insertion assembly toward a media stack and the sensor output changes to a second state and a counter is started. The probe initially encounters the media stack and stops while plunger continues to translate. As the plunger reaches the media stack, the probe engages the sensor causing the sensor output to again change state and stops the counter. The insertion assembly retracts back to the home position where the flag actuates the sensor causing the sensor output to change state.
摘要:
A method of operating an imaging device having a failed or failing media-full sensor determines whether or not a controller can trust the output signal received from the media-full sensor. A reduced power or intensity level is used to test the media-full sensor and, in particular, the light source to counter the dimming of the light source that occurs due to aging and electrical noise in the system. When the output signal of a photoreceptor is at or below a threshold value, the photo-receptor is considered to have not detected the light beam from the light source and the light beam is deemed not to have been detected even though the photo-receptor may be providing a lower level output signal. Thus, an output signal of the photo-receptor is not trusted and an indication that a media storage area is not full is provided and an imaging operation is carried out.

An image forming apparatus has a rotary guide including a path for a sheet being conveyed. The guide is rotatable so that an exit of the path faces one of at least two conveyance destinations. A motor rotates the guide, and a detector outputs a detection signal when a predetermined posture of the guide is detected. An instructing section outputs instruction signals to the motor to rotate the guide toward the predetermined posture. A judging section judges whether a detection signal has been received in response to the instruction signal, and a notifying section counts a consecutive occurrence number of a judgment result to the effect that no detection signal was received in response to the instruction signal this time and gives a notification prompting an inspection request of the image forming apparatus when the consecutive occurrence number reaches a set number.
摘要:
An apparatus for wrapping harvested crop material into bales wherein the wrapping material web is drawn off from a wrapping media supply which rotates about a vertical axis while, at the same time, the bale rotates about a horizontal axis. A sensor is provided which signals a tear in the wrapping media web or the absence of material media. The sensor may be optical ultrasonic or sense electromagnetic radiations of different frequency ranges, as appropriate for the media of which the wrapping media involved. A position sensor is provided which activates an evaluation of signals from the sensor that a signal is produced when the web tears or is absent.
摘要:
An image forming apparatus comprises a conveyance section, a plurality of sensors, an image forming section, a conveyance control section and a control section. The conveyance section forms a conveyance path for conveying paper. The plurality of sensors outputs detection signals indicating the existence of the paper at a plurality of positions along the conveyance path. The image forming section forms images on the paper conveyed by the conveyance section. The conveyance control section controls the conveyance of the paper conveyed by the conveyance section based on the detection signals of the plurality of sensors. The control section determines, in a case in which the detection signal of any of the plurality of sensors is abnormal, whether it is due to sensor failure or paper conveyance abnormality, and sets to ignore the detection signal of the failed sensor and continue the processing if it is due to the sensor failure.
