Try the following:

  • Check that the paper type you have loaded corresponds to the paper type that you select on the front panel and in your software.
  • Check that you are printing on the correct side of the paper.
  • Make sure that you are using appropriate print-quality settings(See the Select print quality section of your HP Designjet Printer User Guide). In some cases, you can overcome a print-quality problem merely by selecting a higher print-quality level. For instance, if you have set the print-quality slider to Fast, try setting it to Best. Alternatively, you could try unidirectional printing. If you change the print-quality settings, reprint your job if the problem has been solved.
  • Try aligning the printheads (See the Align the printheads section of your HP Designjet Printer User Guide). After alignment, reprint your job if the problem has been solved.
  • Check the paper-advance calibration status on the front panel. If the status is PENDING, you should perform paper-advance calibration (See the Perform paper advance calibration section of your HP Designjet Printer User Guide).
