different batch of paper. Do not open packages of | |
paper until necessary so that the paper does not | |
absorb too much moisture. | |

change the printing layout to avoid printing over | |
areas that have overlapping seams on the reverse | |
| side. Printing on seams can cause problems. |

| of a printed page, adjust the print resolution |
| through your software application or via the printer |
| properties window. |
