You can replace the lubricators without service assistance. The operator panel gives an orange warning when you can replace the lubricators.
Use Océ Colorado 1640 prescribed:
Nitrile gloves for handling ink
Bracket with two lubricators and pins (2x)
Crosshead screwdriver
Lint free cloth (optional)
Wear the Océ Colorado 1640 prescribed nitrile gloves. You can only wear the gloves for ten minutes. After ten minutes you must put on new gloves to prevent contact with the ink.
For information on the prescribed maintenance materials, see List of Océ Colorado 1640 maintenance materials.
Touch the printhead carriage on the covered area only, otherwise you can damage the printheads.
When you have replaced the lubricators, some oil can drip on the platen and the platen edge. When oil has spilled: open the top cover when the printer is not printing, clean the oil with a lint free cloth and close the top cover again.
