Looks like a bar code, about 1 inch down and 2 inches from the left. New wiper blade will fix it. We have them available for $10 + $3 shipping/handling. Easy to replace. Pop out the corona assembly from the cartridge unit and 2 screws remove the wiper. Caution should be exercised to place the unit on a towel so the drum doesn't get scratched and don't drop any screws on the drum, it gets expensive if you nick it.
