note:Some of the following solutions require the full feature HP software. If you did not install the full feature software when you installed your printer, go to the software and drivers page, and then download and install the full feature software.
note:Inappropriate paper usually causes vertical streaks in printouts (or, if the problem occurs on a copy, dirty scanner glass usually causes the issue). Do not replace cartridges to fix vertical streaks.

Continue with the following troubleshooting steps if your printout contains horizontal streaks or other print quality issues besides vertical streaks.
|
Do not replace cartridges for vertical streaks in a printout. Instead, check the paper as described earlier in this document, or search for a document that covers this issue.
|
note:Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low ink levels, consider having a replacement ink cartridge available to avoid possible printing delays. You do not need to replace ink cartridges until print quality becomes unacceptable.

caution:Do not use platen cleaners or alcohol to clean the area. These can damage the cartridge or the printer.
caution:Do not touch the copper-colored contacts or the ink nozzles on the cartridge. Touching these parts can result in clogs, ink failure, and bad electrical connections.
caution:Do not clean the ink nozzle plate.
note:Keep a print sample that shows the problem. If the ink cartridges, printhead, or printer is replaced under warranty, the support agent will request the print sample. If the printer is returned to HP, the print sample must be returned with the printer. Place the sample in the output tray when you package your printer for shipping.
