Solution Overview

Problem

Existing image forming apparatuses face challenges in maintaining communication speed during animation display processing, particularly when transmitting operation screens capable of receiving gesture operations, as they require a wide communication band to ensure smooth animation without overwhelming the MFP main body.

Innovation Solution

The apparatus employs beam forming to validate communication for specific terminal devices, adjusting the phase and amplitude of radio waves to enhance signal intensity and transfer rate, allowing for stable and real-time transmission of second-type operation screens, which are necessary for smooth animation display.
