Abstract: An image formation device includes a plurality of motors, an overcurrent detection portion, a load application portion, and a specification portion. The plurality of motors each include an output shaft. The overcurrent detection portion detects an overcurrent with respect to a resultant current including currents flowing through the plurality of motors. The load application portion applies, while the plurality of motors are being rotated, a load to the output shaft of at least some of the plurality of motors. The load applied by the load application portion is a load for causing fluctuation components that enables the currents of the plurality of motors to be distinguished from one another to be generated in the resultant current. The specification portion specifies, when the overcurrent is detected, a motor that is a cause of the overcurrent from among the plurality of motors based on the resultant current.

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: In a two-component developer, toner particles include toner mother particles and external additive particles including strontium titanate particles. A first percentage content being a percentage content of the strontium titanate particles to the mass of the toner mother particles is 0.30-0.90% by mass. The carrier particles include carrier cores and coat layers. The coat layers contain barium titanate particles and a coating resin including a silicone resin. The barium titanate particles have a number average primary particle diameter of 100-500 nm. A second percentage content being a percentage content of the coat layers to the mass of the carrier cores is 2.0-4.0% by mass. A third percentage content being a percentage content of the barium titanate to the mass of the coating resin satisfies formula (1) “(X×10)≤Z≤45.0”. In formula (1), X represents the first percentage content and Z represents the third percentage content.

Abstract: A processor causes a printing portion to execute, when first conveying processing is executed, test print processing for executing processing of forming a plurality of test toner images on a sheet under a print condition that differs for each of the plurality of test toner images. The processor acquires a plurality of first sensing densities when the first conveying processing is executed. The processor causes the printing portion to execute the test print processing when second conveying processing is executed. The processor acquires a plurality of second sensing densities when the second conveying processing is executed. The processor compares the plurality of first sensing densities and the plurality of second sensing densities to adjust the print condition in the print processing when the second conveying processing is executed.

Abstract: A sheet transport device includes a first transport route, a roller, a second transport route, a switching nail, a lever, a sheet detection piece, a cam, an intermediate rotary member, a rotary member, a sensor, a driver, and a controller. The controller controls the driver to switch the switching nail between a first transport position and a second transport position, decides that the sheet is transported through first transport route, when the sheet detection piece retreats contacted by the sheet on the first transport route, with the switching nail being set to the first transport position, and the sensor detects that the rotary member is in the second posture, and decides that the switching nail has been switched from the first transport position to the second transport position, when the sensor detects that the rotary member is in the second posture, after the sheet has passed the sheet detection piece.

Abstract: A first operation restriction portion forms a first step between the first operation restriction portion and a first operation portion. A second operation restriction portion forms a second step between the second operation restriction portion and a second operation portion. A first locking portion releases locking of a locked portion when a first push of pushing the first operation portion or a second push of pushing the second operation portion is performed. When the sheet stopper is rotated in response to the first push, a second locking portion stops the sheet stopper in a first upright state. When the sheet stopper is rotated in response to the second push, the second locking portion allows the sheet stopper to rotate beyond the first upright state. A third locking portion stops the sheet stopper in a second upright state.
