Printhead Nozzle Selection for Reduced Bottom Margin Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers face limitations in achieving precise printing near the bottom margin due to manufacturing tolerances and variations in ink nozzle alignment, necessitating costly modifications to include a secondary media drive system.
Innovation Solution
A shortage model is initiated by selectively using particular ink nozzles within an ink nozzle array to print near the bottom of the media, aligning the printed data with the closest nozzle and turning off distal nozzles to prevent ink application beyond the media edge, without requiring a secondary media drive system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional e-commerce model with large inventory is used, then product availability is improved, but storage costs and risk of unsold inventory increase
Solution Approach 1:
The system performs preliminary actions by pre-ordering products from suppliers before actual customer demand is confirmed. The short-term inventory model allows the system to prepare and stage products in advance based on forecasted demand, ensuring product availability while minimizing the time products spend in inventory. This resolves the contradiction by maintaining reliability through advance preparation without requiring large standing inventory volumes.
2Quantity of substance
If a short-term inventory model is implemented, then storage costs are reduced, but order fulfillment speed may be affected
Solution Approach 1:
The system applies preliminary action by pre-staging products in a short-term inventory before they are needed, based on forecasted demand and lead time analysis. This allows the system to have products ready for immediate fulfillment while keeping inventory volumes low. The preliminary preparation of orders and coordination with suppliers ensures that even with reduced inventory, fulfillment speed is maintained through efficient processes.
Solution Approach 2:
The system replaces traditional mechanical inventory management with an automated information technology-based system. IT systems automatically track inventory levels, predict demand, coordinate with suppliers, and manage fulfillment processes. This substitution enables the system to operate efficiently with minimal inventory while maintaining fast fulfillment speeds through automated real-time monitoring and rapid response capabilities.
3Device complexity
If manual inventory management is used, then system complexity is reduced, but management efficiency and accuracy decrease
Solution Approach 1:
The system replaces manual mechanical inventory management processes with an automated information technology system. IT tools and algorithms automatically perform demand forecasting, inventory optimization, order coordination, and fulfillment tracking. This substitution increases management efficiency and accuracy by eliminating human errors and enabling real-time data processing, while the modular architecture of the IT system keeps complexity manageable through standardized interfaces and processes.

AI summary
Example implementations relate to initiation of a shortage model in a printing device. For example, initiation of a shortage model may include guidance of a page of print media through a printing device by a feedshaft and an upper paper guide, where the page of print media is held by a media control surface. A shortage model may be initiated based on an amount of data to be printed. An ink nozzle may be turned off based on the initiated shortage model.
