Abstract: An image forming system includes at least one piece of image forming apparatus and a server. The at least one piece of image forming apparatus transmits a sleep notification when entering a sleep mode which is a power saving state, and transmits a wake-up notification when returning from the sleep mode to a non-power saving state. The server monitors the sleep notification and the wake-up notification. When a specific image forming apparatus of the at least one piece of image forming apparatus has been in the sleep mode for at least a certain period of time, the sever issues a power-off command to the specific image forming apparatus, so that the specific image forming apparatus shuts off automatically. Before issuing the power-off command, the server delivers a power-off notice to the user who has used the specific image forming apparatus.

Abstract: An image forming system includes an image forming apparatus and a post-processing device. The image forming apparatus includes a scanner reading image data from a sheet, an image forming part forming an image on the sheet, and a sheet ejecting part ejecting the sheet after forming the image. The post-processing device includes a post-processing conveying path, and a stapling part. The post-processing conveying path introduces the sheet from the sheet ejecting part and conveys the sheet. The stapling part collects sheets conveyed on the post-processing conveying path for each predetermined number of sheets and executes staple processing to the sheets. The image forming apparatus or the post-processing device includes a size deciding part deciding a sheet size based on the image data. The post-processing device includes a staple controlling part determining a binding position for the staple processing on the basis of the sheet size.

Abstract: Provided is an image processing apparatus to form an image on a sheet of paper, including a main body and a submodule detachably disposed on the main body. The main body includes an asynchronous serial bus and a master control unit. The submodule includes a slave control unit. An interactive asynchronous serial communication is performed between the master control unit and slave control unit. The master control unit includes a detection timing changing unit. The detection timing changing unit changes a scheduled timing to detect a second signal. The slave control unit includes a transmission signal changing unit. The transmission signal changing unit changes a state of the second signal from a first state detectable by the master control unit at a first timing to a second state detectable by the master control unit at a second timing.

Abstract: An image forming apparatus includes: a transporter for transporting a sheet; an image forming section for forming an image on the sheet being transported by the transporter with an ink; a liquid absorbent member; a cleaning liquid feeding section for feeding a cleaning liquid to the transporter via the liquid absorbent member to clean the transporter adhered with ink residues; and a cleaning liquid feeding controlling section for controlling the cleaning liquid feeding section to perform the cleaning liquid feeding operation, based on a condition of the image forming apparatus relating to evaporation of the cleaning liquid. This arrangement enables to properly clean a transport belt in an inkjet image forming apparatus, while preventing waste of the cleaning liquid and securing stable driving of the transport belt.

Abstract: An inkjet recording apparatus which discharges ink onto a recording medium to form an image, the inkjet recording apparatus including: a recording head having a nozzle for discharging ink; a conveying belt for supporting a recording medium and conveying the recording medium to a position facing the nozzle; a cleaning roller for cleaning the conveying belt; a cleaning liquid storage section for storing cleaning liquid to be applied to the cleaning roller; a contamination detector for detecting a density of contamination of the cleaning liquid stored in the cleaning liquid storage section; a liquid supplying section for controlling supply of cleaning liquid to the cleaning liquid storage section in accordance with a density of contamination detected by the contamination detector; and a liquid draining section for draining at least a part of the cleaning liquid from the cleaning liquid storage section.
