4.7.1 Ink Tubing Reassembly

This section describes how to re-assemble the ink tubes and related
components.
INSTALLING THE CABLE CONNECTION PLATE
1. Attach the HP position and Linear Encoder sensor assemblies to the cable
connection plate.
2. Re-attach the cable connection plate while making sure the Timing Fence
is in the middle of the Linear Encoder sensor. Lightly secure the cable
connection plate with two screws, and connect the ground to the screw on
the left. While looking through the hole on the right side frame to make sure
the timing fence is exactly in the middle of the sensor, tighten the cable
connection plate screws.
Look through this hole to line up the encoder
sensor and the timing fence.
3. Pull the printhead FFCs through the uppper-rear slot in the cable
connection plate. While pulling the ends of the FFCs to remove any slack,
secure the printhead FFCs and the H cable plate with two screws.
4. Fold the right FFC slightly in the middle so the lengths of the two FFCs are
the same.
Disassembly & Assembly

POSITIONING THE TUBE GUIDES AND FFCS

1. Line up the new FFCs and make sure their folds overlap; one FFC will fit
into the fold of the other. The double-sided tape (white) on one of the FFC
cables must be showing on top.
2. Lay down the FFCs in the H Top frame with the multi-folded end protruding
through the hole in the right-side frame. With the double-sided tape facing
the front wall of the H Top frame, put the FFCs in the clips. The fold in the
middle of the FFCs should be right in the middle of the printer.
3. Lay the left-side bottom layer protective film down on the left side and put
the new FFCs on top of that film. Lay the next left-side protective film on
top of the FFCs, and then lay the new tube guide for the light ink on top of
the film.
The side of the tube guide that has only four joints must
attach to the ink pipes in the center. The side with seven
joints must attach to the ink dampers in the carriage.
4. Lay down the right side protective film, and put the new tube guide for the
dark inks on top of the film. Make sure there are only four joints on the ink
pipe end of the tube guide.
Make sure the three ink tubes in the tube guides are straight
and in a constant triangle throughout the tube guides to
prevent the tubes from overlapping, twisting, or pinching.
