note:To purchase paper in the United States and Canada, go to the HP Store.
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.
Examples of horizontal streaks and vertical streaks in the printout

Figure : Horizontal streaks in printout

Continue with the following troubleshooting steps if your printout contains horizontal streaks or other print quality issues besides vertical streaks.
|
Figure : Vertical streaks in printout
|
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 you are prompted to.
caution:Do not lift the latch handle on the carriage to insert ink cartridges. Doing so could cause the printhead or ink cartridges to be incorrectlyseated, which could damage the print mechanism and cause printing problems.
caution:Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.
note:Mechanical noises during the cleaning process are normal.

Windows only: If you are experiencing garbled, jumbled or illogical text, incomplete printouts, or missing text or graphics, go to Continuous Pages of Strange or Garbled Characters Print in Windows
|
caution:Wait until you have a new printhead assembly available before removing the cartridges. HP recommends that you do not leave the cartridges outside the printer longer than 30 minutes. This could damage both the printer and the cartridges.
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.
