A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.

Roasting system with clean emissions and high thermal efficiency

A method of supplying ink to an inkjet printhead having multiple ink color channels. The method includes the steps of: supplying black ink to a black color channel of the printhead; and supplying yellow ink to a yellow color channel of the printhead. The black ink is supplied to the printhead at a lower pressure than the yellow ink.

Method of supplying inks to printhead having multiple color channels

A system for reducing ink color mixing effects in a printer is provided having a printhead having multiple ink color channels mounted to a housing of the printer at a first level, and a plurality of ink supply cartridges mounted to the printer housing so as to be fluidically connected to the printhead and stacked in an array having a plurality of rows defining a plurality of levels which are lower than the first level. The plurality of ink supply cartridges include at least one black ink supply cartridge which supplies black colored ink to a black ink color channel of the printhead. The black ink supply cartridge is disposed at the lowest level defined by the array.

System for reducing ink color mixing effects in printer

Embodiments of the present invention include hybrid ink delivery systems which allow a flexible arrangement of free ink supplies to be connected to multiple printhead assemblies, while preventing printhead deprime or drooling during setup, and provide control and verification of ink supply replacement through the use of integral memory components on the in supplies.

Hybrid ink delivery system

A fluid-ejection assembly of one embodiment is disclosed comprising first and second arrays of fluid-ejection mechanisms, first and second service stations, and first and second drive mechanisms. The first array ejects fluid onto media; the first service station is to service the first array. The second array ejects fluid onto the media; the second service station is to service the second array. The first drive mechanism moves the first array between a first position to eject fluid onto the media and a second position at the first service station, while the second array ejects fluid onto the media in place of the first array. The second drive mechanism moves the second array between a third position to eject fluid onto the media and a fourth position at the second service station while the first array ejects fluid onto the media in place of the second array.

Fluid-ejection assembly

A printhead for printing on a print media includes a column of nozzles oriented at an angle to an axis of relative movement between the printhead and the print media, and a print axis oriented substantially parallel to the axis of relative movement between the printhead and the print media such that at least some of the nozzles are variably aligned to the print axis.

Printhead orientation

The present invention provides a low profile stackable Internet appliance printer for use with a television receiver and monitor and responsive to commands from a remote device for printing user desired information. The printer has a box like rectangular shaped housing conforming in size to that of conventional electronic audio video components such as cable boxes, DVD players, amplifiers, video tapes and the like to facilitate the stacking of the printer with such other components. A base member supports in a front portion of the printer a printbar and associated printheads to provide the user with easy printhead head access. The base member has an open bottom for receiving a removable combination input/output tray cassette. Upon removal of the combination input/output tray cassette, front user access is made available for the purposes of removing a paper jam should one occur. A channel member mounted to the base member helps define a paper path from the cassette to a print zone disposed beneath the printbar. A U-shape cutout in the channel member further provides user access to the paper path for facilitating the removal of paper jams while the printer is in a stacked configuration with other electronic devices.

Media channel and method of clearing media jams

Combined ink-jet printer, facsimile and copier

A suspendable or hanging sheet receiving bin for a printer or plotter which includes a front wall, a back wall, and a bottom wall, all joined together in a bar or wire grid network to define a sheet receiving region. The sheet receiving region has a length dimension, a width dimension, and a depth dimension all defining at one end of the bin an opening for receiving paper fed from the output of the printer or plotter. The front wall of the bin includes a plurality of U-shaped or hook-shaped members having upwardly faced convex surfaces for receiving stacked sheets of paper falling into the opening of the bin and for enabling the sheets to be stacked uniformly and readily accessible to an operator for removal from the bin after the completion of the printing or plotting operation. Advantageously, the bin is provided with an adjustable tray or lever member which may be positioned at different locations along the depth dimension of the bin for receiving different length sheets from the plotter or printer. Additionally, hook members or the like are provided on the wire or bar grid network for positioning the depth dimension of the bin at a predetermined angle with respect to the free fall vertical direction of paper ejected from the printer or plotter.

Hanging bin for uniformly stacking cut sheets at the output of a plotter

A method and apparatus for stacking cut sheets of printed media wherein the leading edge of sheets received from a printer or plotter are first passed vertically downward into a bin and then rotated through an angle away from the printer or plotter. The front side member of the bin has a convex, upwardly facing and smoothly contoured section thereof over which cut sheets are laid with a uniform weight distribution and then down into an adjacent sheet output collection tray. This method of sheet transport and stacking has the advantage of minimizing the crumpling and curling of the cut sheets during the sheet handling and accumulation process. In addition, this method rapidly and efficiently moves the cut sheets out of the way of upstream sheet feeding to thereby prevents paper jam and crushing of paper in the plotter or printer. The apparatus for carrying out this method is of economical and durable construction and may be readily retrofitted to existing large size plotters for handling and stacking relatively large size cut sheets of printed media.
