Image Forming Unit Waiting Time Control for Printer Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image processing apparatuses have a limited lifetime for the image forming unit due to unnecessary operations, which affects the overall efficiency and longevity of the device.
Innovation Solution
The apparatus includes multiple medium storage portions, a medium feeding unit, an image forming unit, a storage unit, and a control unit that manages waiting times to synchronize the feeding and image formation processes, reducing unnecessary operations of the image forming unit by implementing a waiting period based on the image formation waiting time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the image forming unit starts image formation immediately after medium feeding begins, then the productivity is improved, but the image forming unit performs unnecessary operations reducing its lifetime
Solution Approach 1:
The control unit performs preliminary calculation of the waiting time based on the distance between the medium feeding unit and the image forming unit before the actual operation. This pre-calculated waiting time ensures that the image forming unit only performs necessary operations, avoiding unnecessary rotations and extending its lifetime while maintaining efficient productivity.
2Duration of action of stationary object
If the image forming unit waits for the medium to reach the image forming unit after medium feeding starts, then the lifetime of the image forming unit is extended, but the overall processing time increases
Solution Approach 1:
The control unit uses feedback information about the medium feeding progress and calculates the appropriate waiting time based on the distance between the medium feeding unit and the image forming unit. This feedback mechanism ensures that the image forming unit waits only for the necessary duration, optimizing both the lifetime of the image forming unit and the total processing time.

AI summary
An image processing apparatus includes a plurality of medium storage portions, a medium feeding unit that feeds a medium from any one of the medium storage portions, an image forming unit that performs image formation to thereby form an image on the medium fed by the medium feeding unit, a storage unit that stores an image formation waiting time after the medium feeding unit starts feeding the medium from the medium storage portion and before the image forming unit starts the image formation, and a control unit that causes the image forming unit to wait for a time interval based on the image formation waiting time, after the medium feeding unit starts feeding the medium.
