If all the test patterns from the Diagnostic Print are correct and you still experience Image Quality problems, here are some of the more likely causes to check:
- The print mode used in your printer is not right for the image you are
printing (this is defined by the printer's front-panel menu selections).
- Make sure that the paper type selected in the Front Panel is the same
as the paper type loaded into the Printer.
- Non-HP driver.
- The RIP (If you are using one).
- The software applications you are using.
