Bronzing
If you are printing on photo paper in grayscale, and you experience a gloss differential problem when
fluorescent light is directly reflected towards you from the print, producing 'bronzed' reflections from the
ink, try one of the following:
●
If using standard print quality options, ensure that the slider is set to Quality (see
Select print
quality on page 43)
●
If using custom print quality options, ensure that the Gloss enhancer option is set to Whole
page (see
If you are printing on photo paper on page 48)
●
Increase the amount of gloss enhancer used (see
If you are printing on photo paper on page 48)

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 133.
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 103.
2. Try using higher print-quality settings (see
Printing on page 42). For instance, if you have set the
Print Quality slider to Speed, try setting it to Quality; if you have already set it to Quality, try
selecting custom options and then More Passes.
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.
