Left Side Frame Removal

1.Remove the top cover.

2.Remove the print cartridge.

3.Remove the auto sheet feed.

4.Disconnect the print head cables from the system board. You may have to open the print head cable connectors on the system board first, then disconnect the cables.

5.Disconnect connectors J4, J5, and J6 from the system board.

6.Remove the machine from the base. To do this, push the frame latches out as you lift the machine from the base. Set the machine aside.

7.Move the carrier in line with the opening in the carrier transport motor frame.

8.Reach through the opening and pull the belt from the carrier.

9.To unlock the carrier guide rod latches, rotate the rod top-to-rear. Gently push the carrier guide rod latches, at each end of the rod, to the rear and lift up the rod until the sensor on the carrier clears the encoder strip. Remove the carrier guide rod through the opening in the left side frame. Be careful not to damage the encoder strip.

10.Pull the ends of the print head cables into the machine, then remove the cables from the 4 retainers in the paper guide start- ing from the right.

11.Disengage the left paper guide latch by carefully moving the rear of the left side frame to the left.

12.Disengage the right side of the paper guide from the latch and lift it from the machine.

13.A latch on the top front end of each side frame holds the trans- port motor frame in place. Push up the latches on the front of the side frames, then pivot the carrier transport motor frame down and out of the side frames.

14.Place the machine on its back and push the left side frame latch to the rear and remove the frame from the machine.

When you reinstall the paper guide, be sure the front edge goes under the rear of the carrier guide. If the paper guide is on top of the carrier guide, push down the front, bottom edge. It will snap under the carrier guide.
