Recording Medium Deformation Reduction in Inkjet Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing devices, particularly inkjet printers operating in start-stop mode, cause deformations in recording media due to prolonged contact with rollers during stops, leading to reduced print quality and potential spoilage.
Innovation Solution
Implementing a method where the recording medium is moved forward and backward in preparation for a stop, positioning segments partially before or after the roller, ensuring no continuous contact during the stop, allowing climatic properties to adapt, thus minimizing deformation.

Engineering Contradiction Analysis
1Productivity
If the printing device operates in start-stop mode with recording medium remaining inside during stops, then productivity is maintained through intermittent operation, but deformations occur due to prolonged contact with rollers
Solution Approach 1:
The system performs preliminary actions before the stop by moving the recording medium back and forth multiple times. This preliminary movement ensures that different segments of the recording medium come into contact with the roller, distributing the contact load and preventing permanent deformation when the stop occurs. The back-and-forth motion is executed in advance of the actual stop to prepare the recording medium for the stationary phase.
2Device complexity
If recording medium segments remain in contact with rollers during stop, then device structure is simple, but climatic properties do not adapt uniformly causing deformations
Solution Approach 1:
The system applies periodic action by moving the recording medium back and forth in a repetitive cycle before the stop. This periodic movement allows different segments of the recording medium to sequentially contact the roller, enabling uniform adaptation to climatic properties across the entire recording medium. The rhythmic motion ensures that no single segment remains in a different climatic state, preventing deformations caused by property mismatches.

AI summary
In preparation for the stop of a printer, a forward and backward movement of the recording medium in the form of a web is implemented so that the segment of the recording medium that is in contact with a roller of the printer given a stop of the printer is moved at least partially before or after the roller. In preparation for the stop, climatic properties of the recording medium may thus be adapted to the climatic properties of the local environment of the roller, where deformations of the recording medium may be advantageously reduced or eliminated.
