An image forming apparatus includes a storage device capable of storing image data, a task processing unit that accesses the storage device and executes a predetermined service task, and an anti-virus protection unit. The anti-virus protection unit applies a search for a computer virus at predetermined timing to the storage device, suspends the virus search when a request for service task processing involving access to the storage device is received during the virus search, and resumes the virus search after the service task processing requested is finished.

Image forming apparatus and control method thereof

An image forming apparatus with a plurality of functions includes an image information member at a position in a scan area of a scanner and outside an original document placement area. Image information which can be read by the scanner and specifies a permitted function or a prohibited function in the plurality of functions is formed in the image information member. Besides, a processing unit is provided which reads the information to specify the permitted function or the prohibited function from the image information read by the scanner and performs a permission or prohibition processing on the function.

In a digital multifunction peripheral that has a fingerprint reader capability, a display panel displays the duration of time from when the user places his finger immovably at the fingerprint read position until a carriage of the scanner actually starts reading the fingerprint. Consequently, the user becomes careful not to move his finger during the fingerprint scan or before or after the scan starts, and a rate of erroneous reading in fingerprint reading can be lowered.

An image forming apparatus may include an image acquiring section for acquiring the image to be printed, an attribute information acquiring section for acquiring attribute information of the recording sheet to be used for printing the image acquired by the image acquiring section from the IC tag attached to the recording sheet and storing the attribute information, a printing control section for controlling the operation of printing the image so as to make the image match the attributes of the recording sheet on the basis of the attribute information acquired by the attribute information acquiring section and an image printing section for printing the image under the control of the printing control section.

An image reader of the present invention comprises a fluctuation detector that can be connected to the external equipment by means of an image data input-output section, and can subject image data, continuous in a first direction and outputted as image information on a test chart is photoelectrically converted by means of a CCD sensor when a mirror set or the test chart is moved in the first direction, to Fourier conversion, thereby obtaining the frequency of a fluctuation of the obtained image data and a maximum value of the amplitude thereof. If the obtained maximum value of the fluctuation amplitude is greater than a given value, the fluctuation detector is used to compare the frequency of the fluctuation and the natural frequency of a drive motor for generating driving force for moving the mirror set or the image. If the fluctuation frequency and the natural frequency are not equal, the value of current supplied to the drive motor is increased.

Image reader for use in image forming apparatus

The image scanning apparatus capable of reading an image by scanning a carriage equipped with a light source, mirrors and the like in a sub-scanning direction of an original document O, is provided, and in this apparatus, the stepping motor is used to drive the carriage, and an open loop control and switching of the exciter are carried out. With this structure, the scanning speed of the carriage can be increased to be higher than the set speed once, and then reduced to the set speed, thus making it possible to shorten the time for the carriage to move from the home position to the top of the document to be scanned, while suppressing the load on the CPU.
