Abstract: A terminal apparatus that can identify contents of work conducted to repair an image forming apparatus with its power supply turned off. A terminal apparatus can communicate with the image forming apparatus. An obtaining unit obtains information related to an error occurred in the image forming apparatus. A display unit displays work required to cancel the error. An input unit causes a user to selectively input contents of work. A control unit stores the contents of work selectively inputted through the input unit in a storage unit when the terminal apparatus stops communicating with the image forming apparatus and transmits the contents of work stored in the storage unit to the image forming apparatus when the terminal apparatus starts communicating with the image forming apparatus.

Abstract: A reading sensor has first and second detection regions. The first detection region has high directivity and detects a thickness of a recording sheet. The second detection region has low directivity and detects a surface roughness of the recording sheet. The material type of the recording sheet is determined based on the detected thickness and surface roughness. Based on the type of recording sheet, conditions for forming images on the recording sheet are determined.

Abstract: There is provided an image forming apparatus that can reduce the burden placed on the user by avoiding input errors and a complicated input operation when making settings for a color/black-and-white mixing operation and can perform a proper recovery even when a sheet determined to be abnormal is included in other sheets. Images are formed on sheets by an MFP 104 in accordance with an image forming job. The sheets on which the images have been formed are conveyed to a stacker tray 1207 detachably attached to the MFP 104. Information relating to the image forming job for the sheets conveyed to the stacker tray 1207 is written into a storage device 1202 provided in the stacker tray 1207.

Abstract: A CPU for a motor driving apparatus of an image forming apparatus excites a predetermined phase winding among plural phases of a stepping motor for a predetermined time period. Thereafter, before a rotation of the motor is started, it is judged whether there is the possibility of deviating a positional relationship between a rotor and a stator of the motor from a positional relationship determined by the excitation of the predetermined phase winding for the predetermined time period, by an external force, on the basis of judgement whether a door is opened for jam treatment. If the possibility of deviation is judged, the predetermined phase winding among plural phases of the stepping motor is excited again for a predetermined time period.
