Abstract
A medium transport apparatus includes a medium transport path through which a medium passes, a path state detection section configured to output a detection value corresponding to a state of the medium transport path, a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, and a storage configured to store history information including the detection value acquired in the past, in which the control section changes the threshold value based on the history information.
Claims18
A medium transport apparatus comprising:
- a medium transport path through which a medium passes;
- a path state detection section configured to output a detection value corresponding to a state of the medium transport path;
- a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, wherein the abnormal condition comprises at least one of jamming or skewing of the medium;
- a storage configured to store history information including the detection value acquired in the past;
- and
- a display section configured to display information,
- wherein the control section changes the threshold value based on the history information, and
- wherein, when the detection value is higher than the threshold value and the control section determines that an abnormal condition has occurred in the medium transport path, the control section causes the display section to display a user interface for urging a user to check whether the determination is true or false and acquires the information about whether the determination is true or false.
A medium transport apparatus comprising:
- a medium transport path through which a medium passes;
- a path state detection section configured to output a detection value corresponding to a state of the medium transport path;
- a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, wherein the abnormal condition comprises at least one of jamming or skewing of the medium;
- and
- a storage configured to store history information including the detection value acquired in the past,
- wherein the control section changes the threshold value based on the history information,
- wherein the storage stores a predetermined setting value, and
- when an average value of a plurality of the detection values acquired in the past is smaller than the predetermined setting value, the control section lowers the threshold value, and when the average value is larger than the predetermined setting value, the control section raises the threshold value.
A method of controlling a threshold value in a medium transport apparatus comprising a medium transport path through which a medium passes;
- a path state detection section configured to output a detection value corresponding to a state of the medium transport path;
- a control section configured to compare the detection value output by the path state detection section with a threshold value for the detection value and determine whether an abnormal condition has occurred in the medium transport path, wherein the abnormal condition comprises one of jamming or skewing of the medium;
- a storage configured to store history information including the detection value acquired in the past;
- and
- a display section configured to display information,
- the method comprising:
- changing the threshold value based on the history information,
- wherein, when the detection value is higher than the threshold value and the control section determines that an abnormal condition has occurred in the medium transport path, the control section causes the display section to display a user interface for urging a user to check whether the determination is true or false and acquires the information about whether the determination is true or false.
