Poor print quality and unexpected printouts | HP PRO L7500 instruction

Chapter 10

Check the device location and length of USB cable

High electromagnetic fields (such as those generated by USB cables) can sometimes cause slight distortions to printouts. Move the device away from the source of the electromagnetic fields. Also, it is recommended that you use a USB cable that is less than 3 meters (9.8 feet) long to minimize the effects of these electromagnetic fields.

If the above solutions do not work, the problem may be caused by the inability of the application to interpret print settings properly. See the release notes for known software conflicts, refer to the application's documentation, or contact the software manufacturer for specific help.

The device prints half a page, then ejects the paper

Check the ink cartridges

The ink cartridges may have run out of ink, and the print job was cancelled. Replace the ink cartridges, and then resend the print job to the device. For more information, see Replace the ink cartridges.
