Usage information collection
The HP cartridges used with this product contain a memory chip that assists in the
operation of the product.
In addition, this memory chip collects a limited set of information about the usage of the
product, which might include the following: the date when the cartridge was first installed,
the date when the cartridge was last used, the number of pages printed using the
cartridge, the page coverage, the printing modes used, any printing errors that might have
occurred, and the product model. This information helps HP design future products to
meet our customers printing needs.
The data collected from the cartridge memory chip does not contain information that can
be used to identify a customer or user of the cartridge or their product.
HP collects a sampling of the memory chips from cartridges returned to HPs free return
and recycling program (HP Planet Partners: 
www.hp.com/recycle). The memory chips
from this sampling are read and studied in order to improve future HP products. HP
partners who assist in recycling this cartridge might have access to this data, as well.
Any third party possessing the cartridge might have access to the anonymous information
on the memory chip. If you prefer to not allow access to this information, you can render
the chip inoperable. However, after you render the memory chip inoperable, the cartridge
cannot be used in an HP product.

							▲Look at the Ink Level indicators 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
Example of Good Color BarsAll seven bars are solid, sharp-edged, and extend with uniform
color all the way across the page - the printer is operating correctly.
▲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.
The bars correspond to the ink cartridges in the printer as follows:
ItemCartridge color
1Black Ink Cartridge
2Cyan Ink Cartridge
3Magenta Ink Cartridge
4Yellow Ink Cartridge
Ragged, irregularly streaked, or faded bars
Example of Bad Color BarsThe top bar is irregularly streaked or fading.
Print and evaluate a print quality report 51
 
						

							Example of Bad Color BarsThe top black bar is ragged on one end.
If any of the bars are ragged, irregularly streaked, or faded, follow these steps:
1.Make sure the ink cartridges have ink.
2.Remove the cartridge corresponding to the streaked bar and make sure it is properly
vented. For more information, see 
Replace the ink cartridges.
3.Reinstall the cartridge and make sure all the cartridges are properly latched. For more
information, see 
Replace the ink cartridges
4.Clean the printhead. For more information, see 
Clean the printhead
5.Try another print or reprint the Print Quality Diagnostic report. If the problem still
occurs, but cleaning seems to have helped, clean again.
6.If cleaning does not solve the problem, replace the cartridge that corresponds to the
ragged bar.
7.If replacing the ink cartridge does not help, contact HP - the printhead may need to
be replaced.
Preventing the problem that causes ragged bars on the Print Quality Diagnostic
report:
• Avoid leaving opened ink cartridges outside of the printer for an extended period of
time.
• Wait until a new cartridge is ready to be installed before removing an old ink cartridge.

							Regular white streaks in the bars
If any of the color bars show regular white streaks, follow these steps:
White streaksThe print quality bars have white streaks in them.
1.If the Print Quality Diagnostic report reads PHA TTOE = 0, align the printer. For more
information, see 
Align the printhead.
2.If PHA TTOE is not 0, or aligning does not help, clean the printhead. For more
information, see 
Clean the printhead.
3.Print another Print Quality Diagnostic report. If the streaking is still there, but seems
better, try another cleaning. If the streaking gets worse, contact HP - the printhead
may need to be replaced.
Bar colors are not uniform
Print quality bars are not uniformThe bars have lighter or darker portions in them.
If the color of any of the bars is not uniform, follow these steps:
1.If the printer was recently transported at a high altitude, try a printhead cleaning.
2.If the printer was not recently transported, try printing another Print Quality Diagnostic
report. This will use less ink than a printhead cleaning, but if it is not effective, try a
cleaning.
3.Retry the Print Quality Diagnostic report. If the colors seem to be improving, continue
cleaning. If the colors get worse, contact HP - the printhead may need to be replaced.

							Large Black Font Text
Look at the large-font text above the color blocks. I ABCDEFG abcdefg The type should
be sharp and clear. If the type is jagged, try aligning the printer. If there are streaks or
smears of ink, clean the printhead.
Example of good Large-Font TypeThe letters are sharp and clear - the printer is operating
correctly.
Example of bad Large-Font TypeThe letters are jagged - align the printer.
Example of bad Large-Font TypeThe letters are smeared - clean the printhead and check if the
paper is curled. To avoid curl, store all paper flat in a
resealable bag.
Example of bad Large-Font TypeThe letters are ragged on one end - clean the printhead. If this
defect occurs right after a new black cartridge is installed, the
printers automatic servicing routines may solve the problem
in a day or so, using less ink than a printhead cleaning.
Alignment Patterns
If the color bars and large font text look OK, and the ink cartridges are not empty, look at
the alignment pattern directly above the color bars.
Example of a good alignment patternThe lines are straight.

							Examples of a bad alignment patternThe lines are jagged - align the printer. If that does not
work, contact HP.
If you see no defects
If you do not see any defects on the print quality report, then the printing system is working
correctly. There is no reason to replace supplies or have the product serviced, because
they are functioning properly. If you still have a print quality problem, here are some other
things you can check:
• Check the paper.
• Check the print settings.
• Make sure your image has sufficient resolution.
• If the problem seems confined to a band near the edge of your printout, use the
software you installed with the product or another software application to rotate the
image 180 degrees. The problem might not appear on the other end of the print.
