The original is of poor quality. | Moiré patterns, such as bands, checks or stripes in the picture after it |
| is copied, are caused by copying a picture of poor quality, such as a |
| newspaper photo. To reduce moiré patterns, try placing the picture at |
| an angle on the glass. Or try placing one or more clear plastic sheet |
| protectors directly on the glass, and then place the original face down |
| on top of the plastic sheet. You can also try reducing the copy by 3%. |
| To reduce or enlarge copies in 1% increments, press and hold down |
| the Reduce/Enlarge button and then press the Plus (+) and Minus |
| buttons. To confirm the setting, press Select/Resume. |

| correct paper type appears in the display and press Select/Resume. |

The nozzles in the print cartridge might be clogged. | Print a self test page by pressing the Menu button until Self Test Page |
