To maintain a uniform spacing between the print media, such as paper, and an inkjet printhead having a large print swath, for instance about 25 millimeters (one inch) wide, a new media support system is provided for inkjet printing mechanisms, such as printers or plotters. The support system employs an endless belt driven from the belt interior surface by a roller drive system that uniformly supports the print media under the reciprocating printhead. The belt may be lined with anti-cockle ribs t...

A sheet feeding apparatus comprising, a feeding device for pinching a sheet and for selectively performing an operation for temporarily stopping a sheet supplied from an upstream side by abutting a leading end of the sheet against a nip of the feeding device and then feeding the sheet toward a downstream side and an operation for feeding a sheet supplied from the downstream side toward the upstream side; a guide mechanism shiftable between a first position near the nip to direct the sheet suppli...

A recording apparatus with a recording unit for recording an image on a recording medium in consonance with an image signal, a feeder for feeding the recording medium to the recording unit, first auxiliary feeding unit, which contact the feeder when the recording medium is cut sheet paper, but which is separated from the feeder when the recording medium is continuous sheet paper in order to form a feeding route for the continuous sheet paper, second auxiliary feeding unit, which contacts the fee...

A sheet convey apparatus and a printer having such a sheet convey apparatus have rock arms rockable around a rotational center of a driven roller on which an endless belt is supported. Urging roller attaching plates for supporting the urging roller, a transmission shaft, urging roller driving arms and urging cylinders are attached to the rock arms, and the urging cylinders can abut against the corresponding urging roller driving arms. Urging force releasing springs are connected between the urgi...

The present invention provides a sheet convey apparatus with a first convey unit for pinching and conveying a sheet, and a second convey unit disposed at a downstream side of the first convey unit and adapted to pinch and convey the sheet. When elongation of the sheet generated between the first and second convey units is t, a convey amount of the first convey unit is L1 and a convey amount of the second convey unit is L2, a relation of L2.gtoreq.L1+t is satisfied. The present invention further ...

A sheet supply apparatus includes a sheet supporting device for supporting sheets, a sheet supply for positively contacting the sheet supported by the sheet supporting device and for feeding out the sheet, a release mechanism for releasing contact between the sheet supply and the sheet, a separation device for separating the sheets fed by the sheet supply one by one, a pair of convey rotary devices for conveying the separated sheet, and a controller. The controller effects control such that, aft...

A copy sheet collection station, in one embodiment as used in an ink jet printer, incorporates an exit guide ramp which prevents the sheets deposited into the output tray from being smeared by successively deposited sheets. The exit guide ramp comprises a sheet support surface balanced on a pivot edge, the position of the ramp on either side of the pivot point effectively forming an articulated ramp. A ramp segment on the print zone exit side of the printer has a greater mass than the remaining ...

In a printer of which the installation area is significantly reduced, a paper roller, a pressure roller, an eject roller, and a spur roller carry printing paper at an angle of T to a horizontal plane. A stacker for storing the printed paper horizontally therein includes a fixed stacker base formed by part of a housing bottom wall and an auxiliary stacker that can be pushed in and pulled out from under the stacker base. This design shortens a horizontal distance between the paper feed roller and ...

An ink-jet printer includes a rotary drum having a peripheral surface with a plurality of suction holes arranged therein for rotating at a constant speed, a sheet loader for loading a paper sheet to the peripheral surface of the rotary drum, a sheet holding system for holding the paper sheet on the peripheral surface of the rotary drum by applying negative suction pressure to the paper sheet via the suction holes, and a print head for printing an image by jetting ink onto the paper sheet. The ro...

A device for printing comprising a stationary inkjet-style pen, two stationary motors and a paper holder movable on two axes, a slew axis and an advance axis, wherein the paper is moved into the proper position for each step in the printing process by the paper holder and the two motors.
