Printer Transport Stop Position Correction for Third-Party Rolls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers lack the ability to easily and intuitively correct the transport stop position of a print-receiving medium when using third-party rolls, leading to operational inefficiencies due to differences in thickness, material quality, or surface treatment.
Innovation Solution
A printer system with a controller, feeder, printing head, cutter, and detecting device, along with operation devices to adjust the transport stop position manually, allowing for correction of the transport stop position by transporting the medium upstream or downstream by specific unit amounts based on detection errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated transport stop control is used based on detection device and medium information, then productivity is improved, but manufacturing precision deteriorates when using third-party print-receiving medium rolls due to detection errors caused by differences in thickness, material quality, or surface treatment
Solution Approach 1:
The system detects the actual transport stop position using a detection device and compares it with the target position. When a deviation is detected (as occurs with third-party medium rolls having different thickness or surface treatment), the system automatically calculates and applies a correction amount to adjust the transport stop position, ensuring accurate cutting despite variations in medium properties
Solution Approach 2:
The system dynamically adjusts the transport stop position parameter based on detected deviations. When using third-party medium rolls, the detection device identifies position errors caused by differences in medium parameters (thickness, material quality, surface treatment), and the control device modifies the transport stop position parameter accordingly to maintain cutting accuracy
2Device complexity
If no manual correction capability is provided for transport stop position, then device complexity is reduced, but ease of operation deteriorates when correction is needed for third-party medium rolls
Solution Approach 1:
The system performs self-correction of transport stop position automatically. When detection errors occur with third-party medium rolls, the control device calculates the deviation and autonomously adjusts the transport stop position without requiring manual intervention, thereby maintaining ease of operation while avoiding additional complex manual correction mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables operators to easily correct transport stop position errors, improving operability and ensuring accurate cutting by aligning the transport stop position with the cutting blade, even when using non-standard print-receiving medium rolls.
Implementation Method 1
an element to be detected (black mark) of the transported print-receiving medium is detected by a detecting device (sensor main body)

AI summary
The disclosure discloses a printer including a controller configured to execute a setting process, a transport stop process, and a first transport control process. In the transport stop process, a driving device is controlled to stop transport of a print-receiving medium in a state in which an intermediate position faces a cutter. The intermediate position is between a print part last in order and a print-receiving part located immediately after the print part last in order. In the first transport control process, the driving device is control to transport the print-receiving medium to an upstream side by a first unit transport amount in accordance with an operation of a first operation device or to transport the print-receiving medium to a downstream side by a second unit transport amount in accordance with an operation of a second operation device.
