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. Each indicator element includes a matrix with 5\xd78 pixels for the display of a character. When the supply is off, the input is isolated from the output and an output signal derived from the high voltage supply is provided to the output. The first section features a two-input comparator that produces a PWM signal output with a fast transition in response to trapezoidal output fed as an input and compared to a stable reference signal. A size of the display of the information handling system is detected and the first change in image characteristics is further adjusted based on this size before the adjusted image characteristic in image characteristics is applied.
