Print System Sample Sheet Discharge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional print systems face challenges in achieving both image verification and sample printing simultaneously, leading to user inconvenience due to inconsistencies in the order of printed sheets and reference images.
Innovation Solution
A print system that includes a printing apparatus, a verification apparatus, and an information processing unit, which determines the presence of a discharge tray between the printing and verification units, allowing for controlled discharge of sample printed sheets during print jobs, ensuring they bypass the verification process to maintain consistent order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sample printing is performed during a print job, then user convenience is improved by allowing confirmation of printed color and data, but the order of printed sheets becomes inconsistent with reference images expected by the verification apparatus, causing verification failures
Solution Approach 1:
The patent segments the print job processing into two distinct paths: normal printed sheets go through verification, while sample printed sheets are discharged separately to a different tray. This segmentation allows both verification and sample printing to coexist without interfering with each other's order consistency.
Solution Approach 2:
The patent extracts sample printed sheets from the main verification flow by diverting them to a separate discharge destination. This extraction prevents sample sheets from mixing with the sequential order expected by the verification apparatus, thereby maintaining verification reliability while enabling sample printing functionality.
2Reliability
If sample printing is disabled for all verification jobs, then verification reliability is maintained, but user convenience is lost as users cannot perform intermediate checking even when device configuration allows it
Solution Approach 1:
The patent dynamically adjusts the discharge destination based on whether a sheet is a sample printed sheet or a normal printed sheet. This dynamic control allows the system to adaptively route sheets appropriately, enabling both verification and sample printing functions to operate simultaneously without conflict.
3Adaptability or versatility
If a device with discharge tray is present between printing apparatus and verification apparatus, then sample printing can be accommodated by discharging to the discharge tray, but the system complexity increases due to need for detecting device presence and controlling discharge timing
Solution Approach 1:
The information processing apparatus detects the presence of a discharge tray device and uses this feedback information to dynamically control the discharge destination. This feedback mechanism enables the system to automatically adapt its behavior based on the actual device configuration, supporting sample printing when appropriate without requiring complex manual configuration.

AI summary
A print system including a printing apparatus that prints an image on a sheet, a verification apparatus that verifies a sheet printed by the printing apparatus and an information processing apparatus. The information processing apparatus determines whether or not a device having a discharge tray is present between the printing apparatus and the verification apparatus, and in a case where it is determined that the device is present, controls to discharge a sheet printed in a sample printing to the discharge tray when a timing of the sample printing for a user to confirm printing on the sheet is during execution of a print job in which the printing apparatus and the verification apparatus are used.
