摘要： An interlock/latch system for a machine cover, particularly for an electrophotographic printing machine. A cover latch is provided with a latching mechanism and a set of electrical contacts which are mechanically closed when the cover is closed and the latch engaged. A sensor such as a Hall-Effect sensor is mounted in close proximity to the latch. A magnet in the cover actuates the Hall-Effect sensor when the cover is closed and latched sending a signal to the machine controller. The machine controller prohibits operation of the machine until the signal is received.

摘要： A sheet which entered between a first sheet conveying unit and a second sheet conveying unit is detected by a sheet detecting unit. A loop of the sheet formed with a difference of sheet conveying speeds between the first and second sheet conveying units is detected by a loop detecting sensor. After the sheet detecting unit detected the sheet, if the loop detecting sensor does not detect the loop, a control unit which controls the sheet conveying speed of at least one of the first and second sheet conveying units controls the sheet conveying speed of at least one of the first and second sheet conveying units, thereby reducing an amount of the formed loop.

摘要： An image forming apparatus including a mechanism for forming a visual image on a sheet of paper and a plurality of sheets supply mechanisms each including a sheet storage cassette detachably incorporated therein. A detector for detecting the attaching operation of the sheet storage cassettes in each of the sheets supply mechanisms is also provided. An automatic selecting circuit, which is responsive to the detector, automatically selects the sheets supply mechanisms for which the attaching operation has been detected by the detector. A signal is generated to disable the automatic selecting circuit. The disabling signal enables operation without a cassette attached to the sheets supply mechanism irrespective of the sheet size selected.

摘要： An interlock/latch system for a machine cover (200), particularly for an electrophotographic printing machine is provided with a latching mechanism (202,204) and a set of electrical contacts (206,207) which are mechanically closed when the cover (200) is closed and the latch (202,204) engaged. A sensor such as a Hall-Effect sensor (212) is mounted in close proximity to the latch (202,204). A magnet (214) in the cover (200) actuates the Hall-Effect sensor (212) when the cover (200) is closed and latched sending a signal to the machine controller (29). The machine controller (29) prohibits operation of the machine until the signal is received.

摘要： An image forming apparatus includes an image forming portion, a rotatable endless belt, a plurality of stretching rollers including an inner roller and an upstream roller; an outer member, a pressing member, a moving mechanism; and a control portion. The moving mechanism is capable of changing a pressing amount of the pressing member to the belt or a contacting and separating state of the pressing member to the belt by changing a position of the pressing member. The control portion controls magnification of a toner image, to be formed on the belt by the image forming portion, with respect to a conveyance direction of the belt based on a position of the pressing member by the moving mechanism while the toner image is transferred to the recording material from the belt.

摘要： An image forming apparatus adjusts a size of the loop of the sheet between the fixing unit and the transfer unit, according to a signal from a loop detection unit provided in a sheet conveyance path between a transfer unit and a fixing unit and configured to detect a loop of a sheet. The loop detection unit includes a detecting lever that is provided protrudably and retractably from and into the sheet conveyance path and abuts against the sheet, and a loop detection sensor that is turned on or off by the detecting lever. If the sheet is to be conveyed only by the transfer unit, the detecting lever moves to a retracting position from the sheet conveyance path.
