Printer Tray Paper Refill via Drone Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers often stop printing abruptly due to running out of paper, leading to manual intervention and potential printer driver stack overflow issues, as administrators may not always monitor paper levels accurately.
Innovation Solution
A printer system that includes a paper sensor to detect low paper levels, which sends a notification to a drone to autonomously retrieve and load papers from a storage shelf into the printer tray, ensuring continuous printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual paper loading is used, then device complexity is reduced, but productivity decreases due to printing interruptions
Solution Approach 1:
The system enables self-service by allowing the printer to automatically detect low paper levels and trigger a refill request, which is then fulfilled by retrieving paper from the storage shelf without human intervention. The paper refill robot autonomously navigates to the shelf, selects the correct paper stack, and delivers it to the printer tray.
Solution Approach 2:
An intermediary communication protocol bridges the printer and the mobile robot, enabling automated coordination. The printer sends a paper refill request message when paper is low, and the robot responds by executing the refill task, eliminating the need for direct human intervention while maintaining system simplicity.
2Productivity
If automated paper refill system is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The automated paper refill system is segmented into independent functional modules: a paper sensor in the printer detects low paper levels, a communication interface transmits refill requests, a mobile robot with navigation and paper handling capabilities performs the refill task, and a storage shelf organizes paper stacks. This modular segmentation allows each component to be optimized independently while working together to improve productivity.
3Reliability
If paper sensor monitoring is added, then reliability is improved, but device complexity increases
Solution Approach 1:
The paper sensor provides continuous feedback on paper levels in the printer tray. When the paper count falls below a threshold, the sensor triggers a refill request, creating a closed-loop feedback system that ensures reliable paper level monitoring and automatic refilling, preventing printing interruptions.

AI summary
The present disclosure relates to a printer and a method of loading one or more papers into printer tray. In an aspect, the proposed printer can include a printer tray configured to hold a plurality of papers to be used for printing; and a paper sensor configured to sense when number of papers in the printer tray is below a defined threshold, such that when the number of papers in the printer tray is below the defined threshold, the paper sensor issues a notification message to a drone that in turn is configured to, based on the received notification message, pick up and carry one or more papers from a paper storage shelf and load the picked up one or more papers into the printer tray.
