Paper Feed Roller is dirty. | Clean the Paper Feed Rollers. Cleaning the Paper Feed Rollers will wear the |
| rollers, so perform this procedure only when necessary. |

| on page 41. |
Inside of the machine is dirty. | When performing duplex printing, if the specified page size does not match the |
| actual size of paper loaded in the paper source, the inside will become stained |
| with ink, causing printed paper to become smudged. |
| Perform the Bottom Plate Cleaning to clean the inside of the machine. |
| For details on cleaning, see “Cleaning the Inside of the Machine (Bottom Plate |
| Cleaning)” on page 41. |

To prevent the inside of the machine from getting stained, set the page size correctly.
