The print quality is uneven, too light, or too dark, or lines appear in the printout. What should I do?

• If you notice that your print quality is uneven, too light, too dark, or there are vertical or horizontal lines in the print (banding), try these solutions:

  • Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the printhead, if necessary.
  • Align the printhead.
  • If print results appear grainy or blurry, or have horizontal banding, tint unevenness, or stripes, perform Print Head Alignment and Media Feed Adjustment for the media being used.
  • Raise the temperature of the after heater, and give the after heater and your media time to warm up before printing again.
  • Raising the temperature of the after heater too high can cause the media to shrink, wrinkle, or deteriorate.
  • Make sure the media settings in your RIP software are correct for the media you are using.
  • If you are comparing the print result with the image on your computer screen, the colors may not match. Since monitors and printers produce colors differently, printed colors and screen colors do not always look the same.
  • Make sure that the printer and maintenance covers are closed. Do not open any covers during printing. This can cause the printhead to stop abruptly, resulting in uneven color.
  • Shake the ink supply units. Components in the ink may have settled to the bottom of the liquid. Remove the ink packs and shake them.
