15.3.11 Control of detection of media left in machine upon stoppage of media
conveyance
• When media conveyance is stopped due to a media misfeed, a malfunction, an opened
door, or a unit closure failure, the machine checks for media left inside it.
• If a media misfeed occurs, the machine performs the following detection procedures 1 to
3.
• If there is a malfunction, an open door, or a unit closure failure, the machine carries out
the detection procedures 2 and 3.
1. The machine sets the remaining media information according to the cause of the media
misfeed as it occurs.
2. If media information is left inside the Mechanical Control Board when a media misfeed,
a malfunction, or a unit closure failure occurs or a door is opened, the machine detects
the media that is left inside it based on the actual media location and other data avail-
able from the media information. If the machine determines that there is media left, it
gives the “MEDIA JAM” or “PAPER JAM” message corresponding to the location of the
media left.
3. The machine detects media left using sensors (by performing the same control as in
the control of detection of media left).
15.3.12 Temperature/humidity Sensor
• The Temperature/humidity Sensor detects temperature and humidity inside the machine.
• The detected data are used for image stabilization control, ATVC control, and transfer
output control.
