* Check that the mask and chart disks do not contact each other by rotating them by hand.
(As for the bottom of the disk housing, check the disks by shining light in there with a
penlight.)

order.
* Check that the shading plate of the chart disk does not interfere with the chart sensor.
* Write down the connector number “P5” on the connector of the replaced mask motor with
an oil-based ink (black).
