Image forming system and image forming apparatus, and server

An image forming system comprising:

• an image forming apparatus configured to form an image on a recording medium;
• and
• a management apparatus configured to manage the image forming apparatus,
• wherein the image forming apparatus includes:
• a variable mechanism configured to change from a first state to a second state or from the second state to the first state in response to being physically operated by a user;
• a first state detection unit configured to detect a change in a state of the variable mechanism;
• a second state detection unit configured to detect a change in the state of the variable mechanism at a position different from a position of the first state detection unit;
• an abnormality detection unit configured to detect an occurrence of an abnormal condition of the image forming apparatus;
• and
• a transmission unit configured to transmit a detection result of the first state detection unit, a detection result of the second state detection unit, and a detection result of the abnormality detection unit to the management apparatus,
• wherein the management apparatus includes:
• a determination unit configured to determine whether the abnormal condition is caused by a change in the state of the variable mechanism, based on the detection results transmitted from the transmission unit;
• and
• a notification unit configured to provide a notification that the abnormal condition is caused by a change in the state of the variable mechanism in accordance with a determination result of the determination unit, and
• wherein the determination unit is configured to determine that the abnormal condition is caused by a change in the state of the variable mechanism when a time interval from detection of the change in the state by the first state detection unit to detection of the change in the state by the second state detection unit is shorter than a threshold time and thereafter the abnormal condition is detected by the abnormality detection unit.
