Accumulation Printing Controller Skipping Warm-Up Processing

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In printing devices that perform accumulation printing, the warm-up processing is unnecessarily continued from the time a print job is received until printing starts, leading to user discomfort and reduced energy saving performance.

Innovation Solution

A controller determines whether printing is set to accumulation printing based on received print setting information, skipping unnecessary print preparation processing when accumulation printing is enabled, and storing print job data without performing preparation operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If warm-up processing is performed in parallel with print data reception, then first print out time is shortened, but energy consumption increases and user comfort deteriorates when accumulation printing is set

Engineering Contradiction:

Improvefirst print out timeVSAvoidenergy consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the execution of warm-up processing based on the accumulation printing setting. When accumulation printing is enabled, warm-up processing is suspended or cancelled; when disabled, warm-up processing is executed in parallel with print data reception. This dynamic adaptation resolves the contradiction by making energy consumption conditional on the printing mode.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameter of warm-up processing based on the accumulation printing setting. By detecting whether accumulation printing is set, the controller modifies the warm-up processing behavior (execution vs. suspension), thereby optimizing the balance between first print out time and energy consumption according to different printing scenarios.

2Reliability

If warm-up processing is continued from print job reception until printing starts, then printing readiness is ensured, but user comfort and energy saving performance deteriorate

Engineering Contradiction:

Improveprinting readinessVSAvoiduser comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts warm-up processing execution based on user-selected printing modes. When accumulation printing is chosen, the system understands that printing will be triggered later by user instruction, so continuous warm-up is unnecessary. This dynamic adjustment improves user comfort by avoiding unnecessary operations while maintaining printing readiness when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses the print setting information (accumulation printing flag) received from the user as a trigger to self-adjust its behavior. The controller automatically determines whether to perform warm-up processing based on the user's printing mode selection, eliminating the need for separate user instructions and improving ease of operation.

Inventive Principle:

Principle #25Self-service

AI summary

A printing device includes a controller configured to receive print setting information, determine whether or not printing is set to accumulation printing, perform the printing, in a case where it is determined that the printing is not set to the accumulation printing, and perform a print preparation processing of performing a predetermined preparation operation before printing, in a case where it is determined that the printing is not set to the accumulation printing. The controller is configured to accumulate print job data without performing the print preparation processing, in a case where it is determined that the printing is set to the accumulation printing.
