HP Photosmart 3310 All-in-One Printer - Manual (Page 154)

Clean the print head
Use this feature when the self-test report shows streaking or white lines through any
of the blocks of color. Do not clean the print head unnecessarily, as this wastes ink
and shortens the life of the ink nozzles on the print head.
If print quality still seems poor after you clean the print head, try aligning the printer
using the procedure described in
Align the printer . If print quality problems persist
after cleaning and aligning, contact HP customer support.
To clean the print head from the control panel
1.
Load letter or A4 unused plain white paper into the main tray.
2. Press Setup .
3. Press 5 , then press 2 .
This displays the Tools menu and then selects Clean Printhead .
The HP All-in-One prints a page that you can recycle or discard.
For information on cleaning the print head by using the HP Image Zone software that
came with your HP All-in-One, see the onscreen HP Image Zone Help . For more
information, see also Use the onscreen Help .
Clean the ink cartridge contacts
Clean the copper-colored ink cartridge contacts if a message appears on the color
graphics display that says a cartridge is missing or damaged.
Before cleaning the ink cartridge contacts, remove the ink cartridge and verify that
nothing is covering the ink cartridge contacts or the ink cartridge slot, then reinstall the
ink cartridge. If you continue to get a message that says a cartridge is missing or
damaged, clean the ink cartridge contacts. If you still get this message after cleaning
the contacts, you will need a replacement ink cartridge. Remove the affected ink
cartridge and look at the end-of-warranty date on the bottom. If it is before the end-of-
warranty date, contact HP customer support to obtain a replacement ink cartridge.
Make sure you have the following materials available:
●
Dry foam rubber swabs, lint-free cloth, or any soft material that will not come
apart or leave fibers.
● Distilled, filtered, or bottled water (tap water might contain contaminants that can
damage the ink cartridges).
Caution Do not use platen cleaners or alcohol to clean the ink cartridge
contacts. These can damage the ink cartridge or the HP All-in-One.
To clean the ink cartridge contacts
1.
Unplug the power cord from the back of the HP All-in-One.
Note When you unplug the power cord, any faxes stored in memory are
erased.
2. Lift the ink cartridge access door.
3. Squeeze the tab below an ink cartridge to release the latch inside the HP All-in-
One, and then lift the latch.
