Vertical white lines (streaks)
White streaks (horizontal for portrait prints/vertical for landscape prints) can occur for a variety of reasons but
can almost always be corrected:
• Paper dust can block nozzles and create white lines called streaks. The listed HP PageWide printers and MFPs
monitor nozzle health and clean the print head accordingly. However, streaks may occur, especially, if low-
quality paper is used.
– Use quality paper.
– From the control panel, touch Support Tools > Maintenance > Calibration/Cleaning > Advanced Calibration
Support > Clean the Printhead and touch “Start” to begin the cleaning process.
This normally takes about 5 minutes. The printer will produce a Print Quality Report. If streaks appear in
any of the color bars, continue with the troubleshooting steps presented on the control panel.
– Printing solid color patterns of cyan, magenta, yellow, or black may be needed in some cases to restore
full nozzle health and eliminate streaks. To get further assistance in print-quality troubleshooting, go to
hp.com/support, search for your printer name and select Troubleshooting.
• Cold temperature: Ink will freeze. If the printer has been in a below freezing environment then it may need 24
to 48 hours to completely acclimate after being brought into an operating environment (59° to 86°
Fahrenheit,15° to 30° Celsius).
– Allow at least 24 hours for the device to acclimate to room temperature for initial setup if the device has
been exposed to temperatures below 41° Fahrenheit (5° Celsius).
Ragged or missing colors in
vertical bands from top to

nozzles)
Dirty Power Off: The device should always be powered off using the front panel power button located on the
front lower left of the unit. This ensures the print bar is properly capped and protected. If the power cord is
pulled or power to the unit is lost, the print bar may be uncapped and the ink in the nozzles could dry, creating
streaks. The longer the unit is left in this condition, the more difficult it is to recover.
• Never remove power from the device without first powering off the device using the power button.
• Follow the same printhead cleaning instructions given above for streaking caused by paper dust.
Wrong colors or color
variation in bands from top
to bottom of page (ink
mixing)
Transportation of unit: If the printer is transported to a new location, ink mixing across the nozzles may occur.
This will result in bands of colors being mixed from top to bottom of page.
• When transporting the device after initial setup, power-off the unit correctly and carefully move it on a cart,
keeping it in the correct orientation. Turn the unit on and print a test page as soon as possible (from the
control panel, go to Support Tools > Troubleshooting > Print Quality Pages > Print Quality Report and touch
“Print”). If it’s necessary to clean the print head, use the same instructions given above for streaking caused
by paper dust.
• Printing solid color patterns of cyan, magenta, yellow, or black may be needed in some cases to restore clear
ink mixing. To get further assistance in print-quality troubleshooting, go to hp.com/support, search for your
printer name and select Troubleshooting.
I want to print photos
Stunning results can be achieved when using the correct media:
• HP recommends HP Brochure Paper, Matte 180 g, or HP Brochure Paper, Glossy 180 g, for excellent results
for letter-sized photos or graphics. These papers can be printed on both sides.
• HP also recommends HP Advanced Photo papers that come in a variety of photo sizes. These papers can
only be printed on one side.
Multi-feeds
Sheets can occasionally stick to each other or be damaged such that two or more sheets are held together
when picked. Most often these pages will travel together through the printer and a blank page will be seen in
the printed stack of pages.
• Discard dog-eared sheets or wrinkled sheets.
• Do not mix different paper types in the same tray.
• Load paper one half to one full ream at a time.
• Occasionally, a multi-pick will result in the second sheet shifting from the leading (top) sheet. In these cases,
a sensor will detect that the page is longer than expected and post a message to the control panel. If this
occurs, you can discard the blank sheet(s), check the paper size loaded in the tray, and check that the length
and width settings are adjusted correctly.
