HP F340, F375, F370, F335 Clean the print cartridges, To align newly installed print cartridges

Note If you remove and reinstall the same print cartridge, the HP All-in-One will not prompt you to align the print cartridges. The HP All-in-One remembers the alignment values for that print cartridge, so you do not need to realign the print cartridges.

To align newly installed print cartridges

1.Make sure you have letter or A4 unused plain white paper loaded in the input tray. The HP All-in-One prints a print cartridge alignment sheet.

Note If you have colored paper loaded in the input tray when you align the print cartridges, the alignment will fail. Load unused plain white paper into the input tray, and then try the alignment again.

If the alignment fails again, you might have a defective sensor or print cartridge. Contact HP Support. Go to www.hp.com/support. If prompted, choose your country/region, and then click Contact HP for information on calling for technical support.

2.Load the print cartridge alignment sheet on the left front corner of the glass with the top of the page to the left.

3.Press the Scan button.

The HP All-in-One aligns the print cartridges. Recycle or discard the print cartridge alignment sheet.

Clean the print cartridges

Use this feature when the self-test report shows streaking, white lines through any of the lines of color or when a color is muddy after installing a print cartridge for the first time. Do not clean print cartridges unnecessarily, as this wastes ink and shortens the life of the ink nozzles.

To clean the print cartridges from the HP Photosmart Software

1.Load letter, A4, or legal unused plain white paper into the input tray.

2.In the HP Solution Center, click Settings, point to Print Settings, and then click Printer Toolbox.

Note You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab, and then click Service this device.

The Printer Toolbox appears.

3.Click the Device Services tab.

4.Click Clean the Print Cartridges.

5.Follow the prompts until you are satisfied with the quality of the output, and then click Done.

If copy or print quality still seems poor after you clean the print cartridges, try cleaning the print cartridge contacts before replacing the affected print cartridge.
