Abstract: A peer-to-peer network of printing devices is configured to share printing device information, such as job queue status, configuration information, and resource information for automated load balancing, capability matching, failover, and print splitting operations. A digital front end (DFE) of a printing device establishes connections with the DFEs of other printing devices to manage output within the peer-to-peer network in an automated manner. When a print job is received at a DFE for a printing device, it is evaluated to determine how to best manage the output for the print job.

Abstract: An inkjet ink contains quinacridone pigment, pigment dispersion resin, and aqueous medium. The pigment dispersion resin contains absorbed resin that is absorbed by the quinacridone pigment and unabsorbed resin that is not absorbed by the quinacridone pigment. A ratio of the unabsorbed resin to the pigment dispersion resin is 50 weight percent or less. A sulfur concentration in the 10-fold diluent of supernatant liquid obtained by centrifuging the inkjet ink at 1,050,000 G for three hours is 0.4 ppm or more and 7.0 ppm or less. In an ultraviolet and visible ray absorption spectrum of the 25-fold diluent of the supernatant liquid, light absorbance at a predetermined peak is 0.7 or less. The predetermined peak is a maximum peak in a wavelength range of 400 nm or more and 490 nm or less.

Abstract: An image reading device includes a document tray, a linear conveyance path, a curved conveyance path, a document conveyance device, a scanning device, a length detecting device, an operation device, and a controller. A plurality of conveyance rollers are disposed at a predetermined first interval in the linear conveyance path. In the curved conveyance path, a plurality of conveyance rollers are disposed at a predetermined second interval longer than the first interval. When accepting through the operation device an instruction for conveying an original document through the curved conveyance path, the controller allows conveyance of the original document through the curved conveyance path when a length of the original document detected by the length detecting device is not shorter than the second interval or disallows conveyance of the original document through the curved conveyance path when the detected length of the original document is shorter than the second interval.

Abstract: The developing device includes a development container, a developer carrier, and a toner trapping mechanism. The development container includes a first conveyance chamber and a second conveyance chamber placed in parallel juxtaposition and communicated with each other at their longitudinal both end portions, and the development container contains a toner-containing developer to be fed to an image carrier. The toner trapping mechanism includes a duct, an air inlet port, a trapping filter, and a fan. The duct is connected to the second conveyance chamber, and allows air present in the second conveyance chamber to flow therethrough. The development container has an air vent opened in the first conveyance chamber and communicated with outside of the development container.

Abstract: An image forming apparatus includes an attachment part and a sheet feeding cassette attached to the attachment part. The sheet feeding cassette includes a cassette main body, a lift plate, a lock member and a biasing member. The lift plate is supported in a turnable manner. The lock member is movable between a lock position where a turning of the lift plate is restricted and a release position where the turning of the lift plate is permitted. The biasing member biases the lock member to the lock position. In a state where the sheet feeding cassette is not attached to the attachment part, the lock member is biased by the biasing member to be positioned at the lock position. In a state where the sheet feeding cassette is attached to the attachment part, the lock member is movable either to the lock position or the release position by hand.
