Imaging Device Component Wear Reduction via Dynamic Print Engine Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Imaging devices experience excessive component wear due to prolonged operation with motors running, leading to premature depletion of imaging supplies and print quality issues, caused by delays in image generation and transmission problems.
Innovation Solution
A system and methods that include a controller, raster image processor, and print engine, which adjust the printing performance by enabling or disabling functions such as Advanced Start and Smart Run-Out to reduce churn, optimizing the time to first print and throughput based on image generation speed and success, thereby minimizing wear on components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the print engine operates continuously while images are being generated by the RIP, then productivity is improved, but component wear increases and reliability deteriorates
Solution Approach 1:
The system dynamically adjusts the print engine operation state based on real-time monitoring of image generation status. The print engine transitions between active and idle states depending on whether the RIP has completed image generation, optimizing the balance between productivity and component wear
Solution Approach 2:
The system implements feedback control by monitoring the image generation process and using this information to control print engine operation. The print engine receives signals from the RIP to start or stop operation, creating a closed-loop system that prevents excessive wear while maintaining productivity
2Reliability
If the print engine waits for a long time for images to be available, then component wear is reduced, but productivity deteriorates
Solution Approach 1:
The system performs preliminary action by having the RIP generate images in advance before the print engine is needed. This allows the print engine to start immediately when images are ready, eliminating waiting time and maintaining high productivity while avoiding unnecessary continuous operation
3Productivity
If the print engine is prevented from shutting down while another print job is being processed, then productivity is improved, but component wear increases
Solution Approach 1:
The system dynamically controls the print engine shutdown based on the processing status of subsequent print jobs. When the RIP is actively processing the next job, the print engine remains active to maintain readiness. When no jobs are being processed, the print engine shuts down to conserve supplies and reduce wear

AI summary
An imaging system including a method for reducing component wear in an imaging device which includes receiving a print job in the imaging device, generating an image for each page of the print job, printing each image, determining whether an image generation during at least one of the receiving, the generating, and the printing is slow, and upon a positive determination, disabling one or more functions in the imaging device to adjust a default printing performance of the imaging device, wherein the one or more functions include an advanced start function and a smart-run out function stored in a memory of the imaging device for achieving the default printing performance.
