Assembling Notes
When mounting the duplex unit on the lower cover, follow the steps below.
1) Bring the duplex unit inside the lower cover, with the left end first. Fit the left and right
supports over the paper ejection roller shaft and fit the metal hooks into the openings
provided in the lower cover.
2) At the right end of the duplex unit, snap the DX spring lock into place to secure the duplex
unit. Then, route the DX cover sensor harness through the opening provided in the lower
cover.
For the routing of the harness on the top of the lower cover, see the illustration given on the
next page.
3) At the left end of the duplex unit, set the DX spring lock on the two harnesses (switchback
paper detection sensor harness and DX cam switch harness) and snap it into place to secure
the duplex unit. Then, route those harnesses through the cable guide (shown on the
previous page) and the opening provided in the lower cover.
For the routing of those harnesses on the top of the lower cover, see the illustration given
on
page
6-57.
4) Set the DX inner covers R and L back into place.
