8. Removing the Center Gear

(1)

Remove the paper feed tray.

(2)

Remove the paper guide fences.

(3)

Remove the paper feed tray cover.

(4)

Remove the paper width potentiometer.

(5)

Remove the paper feed tray reinforcing plate. (Four M4 x 8 screws)

(6)

Remove side frames F and R. (Three M4 x 8 screws)

(7)

Remove the mounting screw (M3 x 10), then remove the front and rear shafts.

(8)

Remove the two fixed shaft studs, then remove the mounting screw (M3 x 10) on the center shaft.

(9)

Pull out the center shaft from the two fence blocks and their adjoining components, then remove the
shaft.

(10) Rotate the left and right fence blocks together with the racks to remove.

(11) Detach the E-ring and remove the center gear.

[Precautions for Reassembly]

•

Move the fence racks toward the center when reassembling.

•

Gently turn, but do not secure, the mounting screws on the three shafts until the side frames are
