Read all of the instructions in this section before replacing the ink cartridges.
If you need to remove an ink cartridge temporarily, protect the cartridge’s
ink supply port from dirt and dust. Store the ink cartridge in the same environment
as the CX1500. When storing the cartridge, be sure that the label identifying
the color of the ink cartridge is facing up. Do not store ink cartridges upside
down.
The valve in the ink supply port is designed to contain any excess ink that
may be released. However, careful handling is recommended. Do not touch the
ink cartridge's supply port or area surrounding it.
When an ink cartridge is empty, you cannot continue copying even if the other
cartridge still contains ink. Before copying, replace the empty cartridge.
Ink is consumed in the following operations: print head cleaning, self-cleaning
cycle performed when the CX1500 is turned on, and ink charging after an ink
cartridge is installed.
