Horizontal lines at the end of a cut sheet print

This type of defect affects only the end of a print, within approximately 30 mm of the trailing edge of the paper. You may see some very thin horizontal lines across the print.

To avoid this problem:

1.Print the Image Diagnostics Print. See The Image Diagnostics Print on page 172.

2.Consider printing with roll paper.

3.Consider using larger margins around your image.

Vertical lines of different colors

If your print has vertical bands of different colors along it:

1.Try using thicker paper, choosing from the recommended paper types such as HP Heavyweight Coated Paper and HP Super Heavyweight Paper. See Order paper on page 142.

2.Try using higher print-quality settings (see Printing on page 59). For instance, if you have set the Print Quality slider to Speed, try setting it to Quality.

White spots on the print

You may notice white spots on the print. This is probably due to paper fibers, dust, or loose coating material. To avoid this problem:

1.Try cleaning the paper manually with a brush before printing, to remove any loose fibers or particles.

2.Always keep the cover of your printer closed.

3.Protect your paper rolls and sheets by storing them in bags or boxes.
