Image Forming Apparatus Confirmation Printing Mode Pattern Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General users are unaware of the confirmation printing mode used by servicepersons for test printing, leading to potential misuse of the image forming apparatus without identifying test prints, which can result in unintended charging for test prints.
Innovation Solution
The image forming apparatus includes a processor and memory that allows it to operate in different modes, including a confirmation printing mode where a predetermined pattern is superimposed on printed images, and prompts users to acknowledge the mode before printing, ensuring test prints are identifiable and not charged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the confirmation printing mode is used for test printing, then test prints become identifiable through superimposed patterns, but general users may inadvertently use this mode and print test patterns on their documents
Solution Approach 1:
The patent superimposes a predetermined pattern (such as a grid pattern) on the printed image in confirmation printing mode. This pattern acts as a visual indicator that distinguishes test prints from normal prints, allowing users to easily identify when the apparatus is in confirmation printing mode.
Solution Approach 2:
The control unit displays a message on the display unit indicating that the apparatus is operating in confirmation printing mode. This feedback mechanism informs users of the current mode before printing occurs, preventing inadvertent use of confirmation printing mode for normal document printing.
2Reliability
If the confirmation printing mode is always active, then all prints are identifiable, but servicepersons cannot perform normal printing without the pattern overlay
Solution Approach 1:
The patent implements a switchable confirmation printing mode that can be turned on or off by servicepersons through operation of the operation unit. This dynamic control allows the apparatus to adapt between confirmation printing mode (with pattern overlay) and normal printing mode (without pattern overlay) based on operational needs.
Solution Approach 2:
The control unit provides multiple functions: it can display information about the confirmation printing mode setting, accept instructions to switch the mode on or off, and control the printing process accordingly. This multi-functionality allows servicepersons to manage both test printing and normal printing requirements through a single integrated system.

AI summary
An image forming apparatus to function as an input unit configured to input image data, a printing unit configured to print an image based on the image data input by the input unit, a control unit configured to perform control to, if the image forming apparatus operates in a first mode, print by the printing unit an image generated from the image data input by the input unit, and if the image forming apparatus operates in a second mode, print by the printing unit an image obtained by adding a predetermined pattern image to the image generated from the image data input by the input unit, and an accepting unit configured to, if the image forming apparatus operates in the second mode, accept selection regarding whether to perform printing in the second mode in response to operation performed to start printing the image.
