A sheet conveyance apparatus includes: a speed detection roller that detects a conveyance speed of a sheet by coming into contact with the sheet being conveyed and being driven to rotate; and a hardware processor that performs temperature control to make an ambient temperature of the speed detection roller a predetermined temperature.

An information processing device includes circuitry. The circuitry is configured to control a temperature of a heater. The heater performs heating in a printing process. The circuitry is further configured to measure an elapsed time from satisfaction of a given condition, and to determine whether the elapsed time is equal to or longer than a given time. The circuitry is configured to cause the temperature of the heater to rise based on a determination that the elapsed time is equal to or longer than the given time.

Disclosed is an imaging system, which may include: an image forming apparatus including a conveyer, a sheet feeder on which recording media are exposed to an outside, a first hardware processor that causes the conveyer to convey the recording media one by one, an image former, and a first communicator; and an imaging apparatus including an imager, a second hardware processor that causes the imager to image documents one by one in accordance with a timing at which the conveyer conveys each document, the plurality of documents being the plurality of recording media loaded on the sheet feeder to be imaged, and a second communicator that communicates with the first communicator. The imaging system performs: transmission of first information for determining an imaging timing from the first communicator to the second communicator; and/or transmission of second information for determining a conveyance start timing from the second communicator to the first communicator.

An image forming apparatus includes a temperature detecting unit configured to detect a temperature outside the image forming apparatus, a storage portion, and a control unit configured to execute a dew condensation eliminating operation for eliminating dew condensation in the image forming apparatus based on a detection result of the temperature detecting unit. The control unit stores, in the storage portion, an execution time of the dew condensation eliminating operation executed when a power supply to the image forming apparatus is stopped during the dew condensation eliminating operation and determines, when the power supply to the image forming apparatus is started, whether or not to execute the dew condensation eliminating operation based on the execution time and a power supply stop continuing time from when the power supply is stopped to when the power supply is started.

An image forming apparatus includes a dew condensation removal unit configured to execute dew condensation removal processing if it is determined that dew condensation may have occurred in the image forming apparatus, a reception unit configured to receive a print job for instructing execution of print processing, a restriction unit configured to restrict the execution of the print processing during execution of the dew condensation removal processing, a display control unit configured to control a display unit to display a selection screen for selecting whether to execute or cancel the print processing based on the print job if the print job is received during the execution of the dew condensation removal processing, and a print control unit configured to control the print processing to be executed after completion of the dew condensation removal processing if the execution of the print processing is selected.

An image forming apparatus includes a heater, first control circuitry, second control circuitry, and a detector. The heater is configured to heat an inside of the apparatus. The first control circuitry is configured to cause the apparatus to be in a standby state, a sleep state having smaller power consumption than the standby state, or a deep sleep state having smaller power consumption than the sleep state. The second control circuitry is configured to control an operation of the heater. The detector is configured to detect humidity of the inside of the apparatus. The first control circuitry causes the apparatus in the deep sleep state to periodically and temporarily return to the sleep state, and the second control circuitry operates the heater according to the humidity detected by the detector in the sleep state to which the apparatus has returned from the deep sleep state.

A platen assembly in an image-forming device is designed to assist visually impaired users in situating a document into the home corner of the platen. The platen assembly has a pair of placement-assisting thermal strips disposed extending along intersecting sides of the platen. A temperature gradient is established in the thermal strips, by a warming source provided at common ends of the thermal strips, by the thermal strips being an electrical-resistance heating material and a cooling structure or device being provided at common ends of the strips, or by the thermal strips substantially consisting of a thermoelectric material. To further assist a user in situating a document on the platen, the assembly may feature a raised edge extending from the home corner of the platen, along where the pair of placement-assisting thermal strips meet, as well as Braille written strategically on the thermal strips to direct toward the document-orienting corner.

According to a multifunction peripheral according to the present disclosure, when a DC mixing detection circuit detects that electric source power contains DC power, a DC detection signal Sdc is output from the DC mixing detection circuit. This DC detection signal Sdc is input to a solenoid of a shutoff mechanism. In response, the solenoid turns off a mechanical switch via a movable member. In addition, the DC detection signal Sdc is input to a CPU. In response, the CPU displays an error message on a display and outputs a warning sound from a speaker.
