Solving Ink System Problems
Important An “ink system” refers to one color. It is made up of the ink cartridge, the printhead
and the printhead cleaner.
All three components of an ink system must be used together. The three
components are designed to be used together, and information about their use is
recorded within the ink system. Failure to use them together could result in poor
image quality or a failure of a component at a critical point in printing.
If you transfer a printhead from one printer to another (for example, using transport
mode—see page 10-7, Storing and Moving Your Printer, you should also transfer
the printhead cleaner and the ink cartridge with it.
If you receive an “Out of ink” message and you find that the ink cartridge is empty,
replace it and the associated printhead and printhead cleaner.
Replacing ink systems must always be done under the control of the Replace Ink
Systems button or through specific front-panel prompts. In particular, do not replace
components while the printer is powered off, or by opening the window or doors
other than as prompted.
