Abstract
Disclosed are systems and methods for detecting a printer jam. The systems and methods can include receiving a reference image of a printer opening and a second image of the printer opening. A lack of a receipt between the second image compared to the reference image can be detected. The lack of the receipt can indicate the printer jam. After detecting the printer jam, operation of the self-service terminal can be terminated.
Claims20
A method for detecting a printer jam, the method comprising:
- receiving, at a self-service terminal, a reference image of a printer opening;
- receiving, at the self-service terminal, a second image of the printer opening;
- detecting, by the self-service terminal, a lack of a receipt between the second image compared to the reference image, the lack of the receipt indicating the printer jam;
- and
- terminating, by the self-service terminal, operation of the self-service terminal upon detecting the lack of the receipt.
A system for detecting a printer jam, the system comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, causes the processor to:
- receive a reference image of a printer opening,
- receive a second image of the printer opening,
- detect a lack of a receipt between the second image compared to the reference image, the lack of the receipt indicating the printer jam, and
- terminate operation of a self-service terminal upon detecting the lack of the receipt.
A self-service terminal comprising:
- a printer including a printer opening sized to allow a receipt to pass from an interior of the printer through the printer opening;
- a camera arranged to capture images of the printer opening;
- a controller operative to:
- cause the camera to capture a reference image of the printer opening,
- cause the printer to print the receipt,
- cause the camera to capture a second image of the printer opening,
- perform image subtraction using the second image and the reference image to detect the presence or absence of the receipt,
- terminate operation of a self-service terminal upon an absence of the receipt, and
- activate an error indicator of the self-service terminal in response to the absence of the receipt being detected.
