What is the Ink System?
For each of the four colors of ink in your printer’s ink system, there are
three separate components that work together as a system. The components
for each ink color are color-coded to help you install them correctly.
Ink Cartridge
The ink cartridges are a large-capacity ink supply from which the
printheads are refilled whenever the ink volume in the printhead drops
below a minimum level.
Printhead
The printhead has a 600 dpi thermal inkjet head for firing ink droplets onto
the media and a reservoir which holds enough ink for a large number of
prints. The actual number of prints between refills depends on the size and
type of images you are printing.
Printhead Cleaner
The printer uses the printhead cleaner to clean and maintain the printhead
to ensure the best possible image quality, and to seal the printhead when it
is not in use to prevent it from drying out.
How Do I Troubleshoot the Ink System?
1 If the error message IInk system IncompltI appears on the
front-panel it means that the ink cartridge valve has been disconnected,
so:
D If this is the first failure try to REINSTALL the failing Ink System.
D If the failure has been very frequent REPLACE the failing Ink
System (The valve could be damaged).
If this doesn’t solve the problem, continue with the following process.
