Press down the ID sensor shutter (X in the figure below) inside the BK drum unit by hand, and correct the ID sensor shutter
dislocation or come-off.
After that, close and open the top tray at the state of closing the RFID holder to check if the ID sensor shutter can be slide
horizontally.
If the ID sensor shutter comes off and cannot slide, it covers the ID sensor even if the top tray is closed.
Then, acquiring the correction fails because the ID sensor covered cannot scan patch patterns drawn on the transfer belt at
the color registration executed when turning on the main power, etc. (Note 2)
As a result, the color registration is executed based on the correction that was normally acquired last time, the difference with
the actual state of the machine is widened per the execution of the color registration and the color registration drift gradually
appears.
Note 1: The ID sensor shutter may come off due to contact of the Bk drum unit if detaching the Bk drum unit in the order of
right and left side. (Normally, it is recovered by pressure of the transfer belt unit from upside when reattaching the
transfer belt unit. If detaching the Bk drum unit in the order of right and left side, to make sure, please confirm the ID
sensor shutter's sliding motion by opening and closing of the top tray after closing the RFID holder, and recover it if
necessary.)
Note 2: If acquiring the correction fails when executing the color registration, the error message does not appear. While the
failure or success of the acquirement can be checked by referring to the numeric (Refer to the figures in the next
page) of the calibration result on the 2nd page of the maintenance report (for MFP) or the service status page (for
Printer). ("00" means the success and other numeric means the failure.)

* In the normal operation, the ID sensor shutter opens by sliding
rightward when closing the top tray, and it closes by sliding
leftward when opening the top tray. (Above is the state when
opening the top tray.)
