Abstract: Acoustic Transfer Assist (ATA) systems are used in media printing devices to help transfer toner to paper by use of ultrasonic vibrations. A transducer (10) is driven at its resonant frequency, though somewhat dampened. To shorten the decay time of the transducer when its vibration is not desired, a compensating signal is used. A reverse drive voltage is used during transducer shut-off. The reverse drive causes the transducer to vibrate at its normal resonant frequency, but at a 180° phase shift, causing the transducer to stop vibrating significantly faster than without a reverse drive. An open phase-locked loop system drives the transducer from resonance to rest. When the transducer stops vibrating, current to the reverse drive loop is cut off.

Abstract: A bottom vacuum corrugated feeder (BVCF) includes a tray for supporting a stack of documents. The tray is angled downhill relative to the feeding direction of the documents such that the leading edge of the stack is urged to a common stop member. The tray also includes a single side guide for aligning one side edge of the stack. A stack height sensor sends a signal corresponding to stack height to a controller which in turn controls voltage to be applied to a DC motor controlled blower based on a predetermined ratio of air flow pressure to stack pressure. The structure enables intermixed size document feeding in a BVCF.

Abstract: The sheet registering appts comprises a belt partially entrained around a drive member forming a selected arcuate configuration with an outer surface of the belt being adapted to contact a topmost sheet of the stack to urge the sheet into a registered position. A restraining device operatively associated with the belt maintains the belt in the selected arcuate configuration as the sheets in the stack increase. The drive member comprises a rotatably supported, driven roll about which the belt is partially entrained. A sheet compiling tray is disposed adjacent to the belt for receiving sheets to be compiled into the stack and includes an end registration edge adjacent to the discharge nip. A rotatable idler member is adjacent the drive member so as to form a sheet discharge nip with it. for ejecting a compiled sheet stack from said sheet compiling tray.

Abstract: PROBLEM TO BE SOLVED: To provide a method and system evaluating performance of a printing device.SOLUTION: A diagnostic routine is executed in the printing device. The diagnostic routine evaluates performance of the printing device using a set of instructions stored on a computer-readable medium. The set of instructions are configured to identify a fault in the performance of the printing device based on an artifact identifiable on at least one diagnostic output. The diagnostic output is generated by the printing device with the identifiable artifact in accordance with the diagnostic routine for identifying the artifact and associated fault of the printing device.

Abstract: PROBLEM TO BE SOLVED: To quickly dampen vibrations of a transducer when the transducer is turned off.
SOLUTION: A media output device includes a drive belt configured to propagate printable media along a print path, the transducer for emitting ultrasonic vibrations that assist in adhering toner to the printable media, and a transducer drive control circuit for providing a drive signal to the transducer. The transducer drive control circuit includes an inverted drive portion that selectively inverts the drive signal to dampen vibrations of the transducer.
