Note Icon.png  NOTE
  • Replacement ITMs are delivered empty (without ink). It is recommended to keep at least 2 ink cartridges on site for ITM replacement.
  • The main ink and gutter filters are situated in the ITM and are an integral part of the printer's ink system. Replacement of these filters therefore occurs automatically during scheduled ITM replacement.
  • The messages, 'The ITM life is soon to expire. Ensure a replacement ITM is available' and 'Intelligent Ink System is in depletion mode to prepare for ITM change' will appear near the end of the ITM life. Printing will not continue beyond the expiry of the ITM life.
  • The ink system will automatically run down the level of ink in the ink cartridge to a minimum level, so it is usual to replace the ink cartridge at the same time.

  • Paper towels (or similar) and wash are required for this procedure.

Step 1

Disconnect the Printer from Power

  1. If the printer is on, press and hold the Power Button.png button for 2 seconds and wait for the printer to shut down.

  2. Disconnect the power lead from the rear of the printer.

Step 2

Remove the Old ITM

  1. Open the access door to the printer ink compartment.

  2. If an ink cartridge is attached to the ITM, remove it by twisting the cartridge anti-clockwise and lifting it out of the printer.

  3. Pull the two ITM retaining clips upwards away from the ITM

  4. Pull the ITM backwards, withdrawing the connecting manifold from the ink block and remove the old ITM.

    Note Icon.png  NOTE
    • If the ITM does not withdraw with moderate pressure, push the ITM fully forward (which will break any seal caused by dry ink) and try again.
    • The manifold pipes will contain residual ink. Take care when removing the ITM to avoid spillage.

Step 3

Prepare the New ITM

  1. Unpack the new ITM and remove the sealing strip that protects the ITM manifold.

  2. Re-use the sealing strip to seal the manifold and ink cartridge connection on the old ITM.

    WARNING

    Unsealed Container. Risk of Fluid Spill.
    General Warning.png

    Use the sealing strip to seal the manifold and ink cartridge connection on the old ITM.

    If the sealing strip is not used to seal the old ITM, ink may leak out of the ITM and cause injury to personnel.
  3. Place paper towel or similar on top of the level sensor modules to catch excess fluid and using wash, remove any dried residual ink from the ink block valve face.

    CAUTION

    Fluid Hazard. Risk of Fluid Leak.
    General Warning.png

    Lubricate the ITM pipes with wash.

    If the pipes are not lubricated, it may not be possible to make a good seal between the ink block and ITM. A bad seal may cause fluid to leak.
