Printer Tray Sorting with Visual Page Range Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in identifying and collecting printed materials from the correct tray, especially when multiple copies of a document are printed, as existing solutions do not adequately address the importance of maintaining the correct order of pages across multiple trays.
Innovation Solution
An image forming apparatus with a sorter unit that sorts printed sheets into sequential portions and outputs each portion to a different storage unit, while a display unit indicates the storage unit for the first or last sheet of each group, allowing users to easily recognize the order for collection.

Engineering Contradiction Analysis
1Productivity
If printed materials are output to multiple storage units, then the printing capacity and flexibility are improved, but the difficulty of identifying and collecting printed materials in the correct order increases
Solution Approach 1:
The system provides visual feedback through display units on each storage unit that show the tray number and page range of printed materials stored therein. This feedback mechanism allows users to immediately identify which storage unit contains the next page needed for collection, enabling systematic retrieval in correct order without confusion or manual searching.
Solution Approach 2:
The display unit acts as an intermediary between the storage units and the user. It translates the complex state of multiple storage units containing different portions of printed materials into simple, actionable information (tray number and page range), mediating the user's collection process and ensuring correct ordering.
2Manufacturing precision
If printed materials are sorted into multiple portions across different storage units, then the sorting precision and organization are improved, but the information required for proper collection becomes more complex
Solution Approach 1:
The printed materials are segmented into multiple portions distributed across different storage units based on page ranges. Each storage unit receives a specific segment (e.g., pages 1-10, 11-20), and the display unit on each unit clearly indicates its segment identity. This segmentation enables precise sorting while the displayed information guides users to reassemble the segments in the correct sequence.
Solution Approach 2:
The system performs preliminary organization by pre-sorting printed materials into sequential portions and placing them in appropriate storage units before user collection. The display units are pre-configured to show the correct tray numbers and page ranges, so users receive ready-to-collect information that eliminates the need for post-printing sorting decisions.
3Ease of operation
If the apparatus provides detailed information about printed material locations, then the ease of collection is improved, but the device complexity increases
Solution Approach 1:
Instead of providing all collection information from a single centralized display, the system implements local quality by placing display units directly on each storage unit. Each display unit shows only the relevant information for that specific tray (tray number and page range), providing localized, context-specific information that reduces overall system complexity while improving user accessibility.

AI summary
An image forming apparatus arranged to produce groups of printed sheets. Each group includes a plurality of sequential sheets. The image forming apparatus includes a plurality of storage units each configured to store the printed sheets produced by an image forming unit, a sorter unit configured to sort the printed sheets of a group into a plurality of portions, wherein the sheets in each portion are in sequential order, and to output each of the portions to a different storage unit, and a display unit configured to display an indication of the storage unit storing the portion including the first or the last sheet of the group such that a user is directed to collect the portion including the first or the last sheet of the group from the indicated storage unit first.
