Abstract: A printing apparatus that prints images onto sheets includes a conditioner that scents selected images of a job. For example, the job can be a magazine that advertises a particular fragrance or fragrances. A fragrance or scent is placed in a reservoir which is transferred via a hydrophilic donor-like roll and deposited onto a sheet by way of a nip that is engaged only when scenting is required.

Abstract: A high voltage MOS transistor, for use in a thermal ink jet printhead, is fabricated with a single, uniformly thick layer of polysilicon that serves as a field plate over the drift region and a gate over the channel region. The fabrication of the drift region and associated drift oxide is performed in a sequence independent of the device channel stop and field oxide fabrication, allowing the drift region to be optimized by varying the thickness of the drift oxide. Using a field plate to increase the breakdown voltage of the device by reducing the concentration of the electric field, the device transconductance is increased by increasing the doping of the drift region without an attendant decrease in breakdown voltage.

Abstract: A paper conditioner to control image dependent curl in a copier/printer includes a nip formed between metering and transfer rolls with grooves positioned on end portions of both of the metering and transfer rolls. Portions of both the metering and transfer rolls are located over a sump connected to a reservoir that supplies liquid to the nip for transfer to the transfer roll. The grooves act as gutters and allow excess liquid to flow into a sump, and subsequently, back into the reservoir. Flaps are positioning in the grooves in order to aid in the flow of fluid back into the sump.

Abstract: Ferroelectric polymer films are applied in a charge transfer imaging process to generate latent electrostatic images on a dielectric receiver media. The dielectric receiver media may be the final imaging substrate which is then xerographically toned and fixed, e.g., Versatec dielectric paper, or an intermediate surface from which a toned image is transferred to plain paper. Charges may be generated applying either the piezoelectric or the pyroelectric effect exhibited by ferroelectric films.

Abstract: A vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top or bottom of a stack. A retractable corrugator is included in the vacuum feedhead which prevents smearing of coated sheets due to relative motion between sheet surfaces and the corrugator.

Abstract: A device and method for controlling sheet moisture and cooling rate for reducing curl in sheets includes the steps of providing a fuser with the fuser being heated at a predetermined temperature; providing a moisturizer; positioning the moisturizer a predetermined distance downstream of the fuser as indicated in accordance with the predetermined temperature of the fuser; and controlling ambient relative humidity around the moisturizer.

Abstract: A ball-on-belt transport includes a belt with a steel ball positioned on top of the belt and a magnet on the back side of the belt with the ball forming a nip with the belt to provide necessary normal force against a conveyed sheet and thereby allowing easy lateral pulling of sheets in clearing jams from the nip. Alternatively, a steel ball is retained while in contact with a belt to apply a normal force to a sheet on the belt equal to the weight of the steel ball. The ball is encased in a housing that is surrounded by a solenoid coil such that when current is applied to the coil, it acts as a solenoid and raises the ball off the belt surface and thus releases the nip pressure.

Abstract: A top vacuum corrugation feeder includes articulating suction fingers to assist in raising the top sheet of a stack of sheets to the feedhead of the vacuum corrugation feeder. The suction fingers are rotated down from their interleaved position between feed belts to contact the top sheet in the sheet stack and raises the top sheet to the feed belts. As a result, the feeder can handle heavy sheets, curled sheets, and sheets which are edge welded.

Abstract: A paper conditioner re-moisturizes paper immediately following fusing to restore paper moisture equilibrium and reduce curl. The paper conditioner uses moisturizing rollers with a textured elastomeric surface that prevents bead buildup of water at a nip formed between the moisturizing rollers and allows the rollers to conform to the surface texture of a sheet of paper passing therethrough.

The system (10) includes a tear strip opening device (40) which provides access to the contents thereof. Structure (60, 66) is provided in each of the opposite sidewalls (24, 25) above the position of the opening device (40) which allows the lid portion (30) to be pressed onto the base portion (20) without detaching the lid portion (30) and base portion (20), the structure (66) in sidewall (25) also forms a hinge about which the lid portion (30) can be rotated once the opening device (40) has been operated.

Abstract: A baffleless, easily accessible, copy sheet transport apparatus without sheet baffles that enables viewing and accessing jammed sheets without opening any baffles. The transport includes a pulley driven narrow timing belt with biased idler rolls providing normal force on belt driven copy sheets. Unobstructive copy sheet side guides are included to enhance viewing and removal of copy sheets from the copy sheet transport.

Abstract: An adjustable, pivoting paper tray that enhances the feeding of a full ream of shorter than standard size paper by a feed roll from the paper tray without encountering stack normal force relief impediments includes a half ream sized adjustable backstop. The backstop has floating or articulating fingers resting on the ream of paper in the paper tray that slide downward as each sheet is feed from the paper tray. This movement of fingers allows every sheet to be fed from the sheet stack.

Abstract: A device for adding controlled amounts of moisture to one or both sides of a copy sheet. The device includes a pair of water jets, a reservoir for storing a quantity of liquid and connected to the water jet, a pair of generally cylindrical, pressure rolls, each having an outer cylindrical surface with the rolls being aligned with respect to one another along their axes so as to define a nip between the outer cylindrical surfaces, and a controller for controlling application of water from the water jets to selected portions of each sheet passing thereunder before each sheet enters the nip formed between the outer cylindrical surfaces. Alternatively, the water jets could apply the liquid to the cylindrical surfaces of the pressure rolls.

Abstract: A system which controls image dependent curl by moisturizing a sheet immediately after fusing, determines critical machine and environmental characteristics through a series of on-line sensors. An operator selectable table is used to indicate the type of sheet loaded in each sheet holding tray.

Abstract: An ionographic printer directs a sheet of ions from a source to a charge receptor to create an electrostatic latent image thereon. An ion sheet splitting rod is positioned between the ion source and the charge receptor that splits the ion sheet into two separate streams of ions and insulating wedges serve to focus the separate ion streams into two rows of apertures in an ion control device. The ion streams pass through relatively large apertures having associated therewith a pinch electrode for narrowing the ion streams to a preselected width, and displacing electrodes for positioning the narrowed ion streams within the apertures.

Abstract: A device and method for measuring the thickness of liquid on an adjustable metering roll. The device comprising a transfer roll that mates with a back-up roll to form a nip through which a sheet passes for wetting a side of the sheet. An adjustable metering roll mates with the transfer roll and has a portion thereof positioned in a liquid filled sump for liquid to be added to an outside surface thereof. An optical sensor is positioned to detect the type of reflected light from the liquid on the outside surface of the metering roll and give off a Go/No Go signal when indicating contact between the metering roll and the transfer roll. The correct liquid thickness is obtained on the surface of the metering roll by further adjsutment of the metering roll.

Abstract: A tape containing a supporting substrate and a magnetic layer coated thereover. This tape can be selected for thermal fusing processes where the coating, after heating of the tape which is in contact with a nonmagnetic image, transfers into the image and renders it magnetic. The corrected image can then be selected for MICR processes and devices.
