Abstract

An image forming apparatus for printing out one or more pages in an electronic file having color information in the form of at least one of character information and image information, includes an information acquiring unit configured to acquire at least one of the character information and the image information from the electronic file; and a blank page determining unit configured to determine whether a page in the electronic file is a blank page based on the color information of at least one of the character information and the image information acquired by the information acquiring unit. A page that is determined as being a blank page by the blank page determining unit is cancelled from being printed out.

Description

technical field [0001] The present invention relates to an image forming apparatus having a function of preventing blank sheet discharge and a method for preventing blank sheet discharge. Background technique [0002] In recent years and later, digital color multifunction peripherals (MFPs) including functions such as a copying function, a facsimile (FAX) function, a printing function, a scanning function, and a function of transmitting an input image have become indispensable in offices. MFPs generally have a device called an ADF (Automatic Document Feeder) that automatically feeds originals so that multiple originals can be scanned at a time. The user can use this function to effectively copy the original. [0003] Conventionally, when blank sheets were included in a batch of originals, the blank originals were printed as blank copies, which resulted in wasted transfer sheets. In an attempt to solve this problem, Patent Document 1 discloses a determination unit for deter...
