ENWW Ink is smearing z Check the printout • The document might not have had enough time to dry. When you are printing documents that use a lot of ink, you must allow the document more time to dry before handling it. This is especially true for transparencies. The Normal print-quality setting for the printer driver is to designed to optimize both drying time and speed. Using this mode allows the print output to dry completely in most situations. However, when printing in very humid environments, use the Best print quality setting to allow a longer drying time. • Too much ink on the page might be causing wrinkling. Color documents with rich, blended colors can use excess ink, which wrinkles the page during printing and causes smearing. Try using the Normal or Fast print quality setting to reduce ink, or use HP media that is designed for printing vivid color documents. z Check the media and media type • Some types of media do not accept ink well, which causes the ink to dry more slowly and results in smearing. See Choosing the print media for more information about media. • An incorrect media type might be selected. The correct media must be selected in the printer driver. Make sure that the media that is selected in the printer driver matches the media that is loaded in the tray. • The media might have been exposed to a humid environment. If media has been exposed to a humid environment, you might have difficulty achieving the correct drying time, especially when printing with heavy color saturation. Print on a fresh ream of media that has been stored in a cool, dry place. z Check the printheads • If the problem occurs repeatedly for jobs, faulty printheads might be the problem. Try cleaning the printheads and then cleaning the printhead contacts. If cleaning does not resolve the problem, replace the printheads. See Cleaning the printheads, Cleaning the printhead contacts, and Replacing the printheads for more information.
