Print quality troubleshooting
Horizontal smears on the front of coated paper
If a lot of ink is used on plain or coated paper, the paper absorbs the ink quickly and expands. As the printheads move over the paper, the printheads may come into contact with the paper and smear the printed image. This problem is normally seen only on cut sheets of paper (not on roll paper).
Corrective Action
1Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can verify the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).
2Use a recommended paper type and the correct print settings.
3If using sheet paper, try rotating the sheet 90 degrees. The orientation of the paper fibers may affect performance.
4Try using a heavier paper type. When printing dense colors, it is recommended to use HP Heavyweight Coated Paper or HP Super Heavyweight Coated Paper.
5Try to increase the margins by relocating the image to the center of the page with the software application being used.
Ink marks on the back of the paper
This can happen after a lot of border less printing, especially with non- standard paper sizes. Ink residues on the platen are likely to mark the back of the paper.
Corrective Action
Clean the platen with a soft cloth. Clean each rib separately without touching the foam between the ribs.
