Care and Maintenance
User replaceable components
When the printer panel indicates that a supply needs to be replaced, make
sure that you have replacement supplies on hand. The printer may continue
to print until the supply is completely used up; but then it stops until you
replace the indicated supply.

These figures are based on an average of 5% coverage of the printable
area and standard density for any one color (refer to Example A below
left: Monochrome 5% coverage). 4 colors (Cyan, Magenta, Yellow and
Black) are used for full color print. The frequency of replacement will vary,
depending on the complexity of the prints and the percentage of coverage
of each color and print density.
Example B below right is the case of full color print. The percentage of
coverage of each color is as follows. Cyan: 40%, Magenta: 22%, Yellow:
35%, Black: 20% If you continuously print with this setting, the average life
of the Color Imaging Unit will be shortened to about 2,500 pages.
