11.2.4.2 Belt Full Displacement Temporary Escape Mode

Purpose
In this machine, belt displacement control is performed to prevent full displacement of fixing belt.
However, belt displacement occasionally occurs. At full displacement, display E007-0001 or 0002 and stop the
machine.
To eliminate downtime of the machine due to the error display, execute belt full displacement temporary escape
mode.
Control contents
When the belt end reaches +2.5/-2.5 from the belt standard position, the displacement control motor is activated
to move the position of the belt (tension roller) to the two-step position (See the belt displacement control).
When the belt end stays there (+2.5/-2.5 from the belt standard position) 10 seconds or more after moving the
belt (tension roller) to two-step position, it is judged that the belt cannot be moved to the center, and full
displacement temporary escape mode is executed.
Perform pressure release of the pressure belt for the full displacement temporary escape mode (While printing/
copying, deliver papers at the machine first and perform this procedure).
When releasing pressure, the belt is moved to the center. If full displacement occurs after the pressure release,
E007-0001 or 0002 is displayed and the machine is stopped.
'Printer in Preparation' is displayed on the control panel during this time.
When the belt returns to the center position, start-up sequence is performed, the pressure belt is pressured and
printing is started again.
*1 The belt is displaced most when applying pressure to the pressure belt. So, it shifts to the center by releasing
the pressure of the pressure belt at the 2 level positions.
