Viscometer Replacement

Note:

Tools required:

Lint--free tissue to catch any escaping ink.
Adjustable spanner (see step (4)).
Protective clothing (especially safety glasses).

The printer must be shut down and the cartridges removed.

(1) Remove the securing screw and pull out the ink system.
(2) Disconnect the viscometer wiring from the ink interface PCB.
(3) Pull the viscometer out of its clips by squeezing each tab and

releasing the clip.

(4) Disconnect the ink tubes from the viscometer and trim the used end

part (approx. 5--6mm) of the tubes, then transfer to the new

viscometer. The tubes must be connected so that when the new
viscometer is fitted into the clips, the tube connectors face the block
(see diagram), the wires must come out of the bottom of the
viscometer.

(5) Fit the new viscometer into the clips and connect the wiring to the

ink interface PCB.

(6) Refit the ink system and the cartridges.
The replacement is now complete. Check for leaks when the printer is
next started up. If a viscometer fault is shown, ensure that the
viscometer is fitted correctly.
