If any of the remaining three lines are missing, faded, streaked, or show lines, this
might indicate a problem with the tri-color print cartridge in the left slot.

Make sure the color blocks have even consistency and are representative of the
colors listed below.
You should see cyan, magenta, yellow, violet, green, and red color blocks.
If color blocks are missing, or if a block of color is muddy or does not match the
label indicated below the block, this might indicate that the tri-color print cartridge is
out of ink. You might need to replace the print cartridge. For more information on
