When all four LEDs on the control panel are blinking, a Maintenance
Error has occurred. When the printer displays the Maintenance Error,
the waste ink pads are full of ink. Replace the waste ink pads with new
ones by following the steps in
“Upper Case and Control Panel
Removal” on page 91 to remove the upper case. Then remove the
screws shown in Figure 4-6 to access the waste ink pads. Replace the
pads with new ones, and then and then clear the waste ink counter by
one of the following two methods:

reset when both Ink Out lights and the Paper Out light are blinking.
