Abstract: An imaging system includes a housing that defines a housing space, a fuser disposed inside the housing space to fix a toner image onto a print medium, a collecting device including an ionizer and a particle filter, and a controller. The fuser is associated with operation history information. The ionizer of the collecting device includes a first electrode and a second electrode. The ionizer generates a discharge between the first electrode and the second electrode so as to charge floating particles that are discharged from the fuser. The particle filter of the collecting device collects the charged floating particles. The controller controls a current to flow between the first electrode and the second electrode due to the discharging, based on the operation history information of the fuser.

Abstract: An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.

Abstract: An image reading apparatus includes an image sensor, a document feeder, and a processor. The document feeder includes a first driving device, a second driving device, a third driving device, a first sensor, and a second sensor. The first driving device includes a pick-up member to move documents from a tray to a document conveying path using a driving force through a first clutch. The second driving device is to move the tray with the documents to a side of the pick-up member using a driving force through a second clutch. The third driving device to move the documents along the document conveying path onto the image sensor using the driving force of the motor The first and second sensors detect the documents on the document conveying path. The processor controls an operation of the first clutch based on the signals of the first and second sensors.
