HP Officejet 6500 - Manual (Page 159)

To evaluate the Print Quality Diagnostic Page
This section includes the following topics:
• Ink Levels
• Good color bars
• Ragged, irregularly streaked, or faded bars
• Regular white streaks in the bars
• Bar colors are not uniform
• Large Black Font Text
• Alignment Patters
Ink Levels
▲ Look at the Ink Level number in Line 21. If any of the bar level indicators are low, you
may need to replace that ink cartridge.
NOTE: Ink level warnings and indicators provide estimates for planning
purposes only. When you receive an ink alert message, consider having a
replacement cartridge available to avoid possible printing delays. You do not need
to replace cartridges until print quality becomes unacceptable.
Good color bars
▲ Look at the color bars in the middle of the page. There should be seven color bars.
The color bars should have sharp edges. They should be solid (not streaked with
white or other colors). They should be uniform in color throughout.
Example of Good Color Bars - all seven bars are solid, sharp-edged, and extend with
uniform color all the way across the page - the printer is operating correctly. The bars
correspond to the ink cartridges in the printer as follows:
Item Cartridge color
1 Black Ink Cartridge
2 Cyan Ink Cartridge
3 Magenta Ink Cartridge
