Ink system maintenance icon
The Number of copies icon is alternating between the letter E and the number 9.
Cause Solution
The printer detects that ink system maintenance is required. Open the printhead access door completely, and then close it
immediately. This process helps remove ink buildup and
maintains the best print quality throughout the life of the printer.
CAUTION: Do not open the blue printhead latch during this
process; otherwise, the printer may require new printheads to
function.
