Abstract: According to one embodiment, a thermal heat transfer printer (printer device) includes a printing data look-ahead unit configured to look ahead a data printing position if printing is performed; a head position control unit configured to cause a thermal head, an ink ribbon, and printing paper to be in a contact state or a non-contact state based on a look-ahead result of the printing data look-ahead unit; an ink ribbon saved amount calculation unit configured to calculate a saved amount of the ink ribbon based on a conveyed amount of the printing paper in the non-contact state; and an ink ribbon saved amount display unit configured to display the saved amount calculated by the ink ribbon saved amount calculation unit.

Abstract: A sheet processing apparatus is described. The sheet processing apparatus includes a housing section, a conveyance mechanism and a controller. The housing section accommodates a sheet. The conveyance mechanism conveys the sheet accommodated in the housing section to a predetermined position at the downstream side in a sheet conveyance direction. The controller controls the conveyance mechanism to remove a needle-free binding section of a sheet bundle if a conveyance jam of the sheet occurs.

Abstract: A toner supply device used for an image forming system for forming images with toner is provided for supplying the toner to the image forming system from a toner cartridge. The toner cartridge has a cylindrical container with a spiral protrusion being formed on the inner surface of the cylindrical container and with a toner-discharging hole being formed on the outer surface of one of two capped end sections of the cylindrical container.

Abstract: An image forming apparatus and method causes a connecting/conveying device to convey a recovered toner from a cleaner part to a recovered toner housing unit to house therein the recovered toner. A controller controls a recovered toner supply unit and new toner supply unit in accordance with a toner concentration ratio in a developing device, which is detected by toner concentration ratio detecting unit, to supply the recovered toner, which is stored in the recovered toner housing unit, and a new toner, which is stored in new toner housing unit, to the developing device.

Abstract: An image forming apparatus and method cause a connecting/conveying device to convey a recovered toner from a cleaner part to a recovered toner housing to house therein the recovered toner, and cause a control device to separately control a recovered toner supply device and a new toner supply device to supply the recovered toner, which is stored in the recovered toner housing, and/or a new toner, which is stored in a new toner housing, to a developing device. The control device restricts the supply of the recovered toner from the recovered toner housing to the developing device when a no-residual-amount detecting device detects no residual amount of the new toner in the new toner housing.

Abstract: The main body of a digital copying machine is connected to a finisher. The main body subtracts a certain length of time from the sheet processing time designated by the finisher. Owing to this, even when the finisher is used, printing processing is executed with no need to decrease the processing speed originally provided for the main body of the digital copying machine.
