When Replacing Components Of The Scanning System; Removing The Standard White Plate - Canon iR7086 Series Service Manual

Chapter 5
When removing the stream reading glass retainer, be sure to take care so that
the leaf spring will not come off.
- When mounting the stream reading glass retainer, be sure to hold down
both sides of the leaf spring [A] with your fingers. (Do not bend the leaf
spring.)
- Be sure to mount the stream reading glass [C] while forcing the stream
reading glass retainer [B] against the glass.
- Check to make sure that the side of the stream reading glass and the leaf
spring [D] of the stream reading glass retainer are in contact. Otherwise,
the possible collection of dust on the stream reading glass will lead to
lines in images.
