Reassembling Notes

• Before reinstalling the top cover, route the FG wire, hook SW-main harness, scanner motor

harness, and CIS harness on the underside of the top cover as illustrated in Subsection 4.1.26,

”Harness routing C."
After installing the top cover, route the FG wire and those three harnesses on the main cover as

illustrated in Subsection 4.1.26, "Harness routing D and E."

• When routing the FG wire, hook SW-main harness, and scanner motor harness through the

cable guides, be sure to first route the FG wire and then route those two harnesses. This may

prevent the FG wire from working out of the cable guides.

• When disposing of top covers, remove two leaf springs from each top cover with a flat

screwdriver to separate 

metallic

 springs from 

plastic

 covers.
