Battery tips
When the battery power is too low to continue printing, you can charge the
battery. You can also continue printing if you plug in the power adapter or
install a charged battery.
Don’t remove the battery in the middle of printing.
When you charge the battery, charge it completely (not partially).
Don’t charge the battery too often without fully discharging it first, since too
much partial charging reduces the battery’s ability to hold a complete charge.
You can avoid charging too often by keeping track of how many pages you
print using the battery. One battery charge yields approximately 200 black-
and-white pages with 5 percent ink coverage per page or approximately 35
color pages with 7.5 percent ink coverage per page. A typical page of text with
no graphics has about 5 percent coverage.
You should discharge the battery completely before you charge the battery.
Completely discharging and then charging the battery can take time, so plan
ahead for this process.
