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 141. 2. Try using higher print-quality settings (see Printing on page 45). 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. Colors are inaccurate Print-quality issues If the colors of your print do not match your expectations, try the following: 1. Check that the paper type you have loaded corresponds to the paper type selected in the front panel and in your software. To check on the front panel, use the View loaded paper key. At the same time, check the color calibration status. If the status is PENDING or OBSOLETE, you should perform color calibration: see Color calibration on page 68. If you have made any changes, you may wish to reprint your job in case the problem has been solved. 2. Check that you are printing on the correct side of the paper. 3. Check that you are using appropriate print-quality settings (see Printing on page 45). If you have selected the Speed or Fast options, you may not get the most accurate colors. If you change the print-quality settings, you may wish to reprint your job at this point in case the problem has been solved. 4. If you are using Application Color Management, check that the color profile you are using corresponds to the selected paper type and print-quality settings. If you have doubts about which color settings to use, see Color management on page 61. If you need to create a color profile, see Color profiling on page 69. 5. If you try to do color management in your application and also in the printer, your results will be wrong. You should manage colors in the application or in the printer, but not in both.
