If an interruption occurs to a job that is printing, the printer might not recognize the rest of the job.

Cancel the print job and wait for the printer to return to the ready state. If the printer does not return to the ready state, cancel all jobs, and wait again. When the printer is ready, resend the job. If prompted by the computer to retry the job, click Cancel.

Check cable connections

If the printer and computer are connected with a USB or parallel cable, the problem may be due to a poor cable connection.

Make sure the cable connections at both ends are secure. If the problem persists, turn off the printer, disconnect the cable from the printer, turn on the printer without connecting the cable, and delete any remaining jobs from the print spooler. When the Power light is on and not flashing, reconnect the cable.

Check the document file

The document file may be damaged. If you can print other documents from the same application, try printing a backup copy of your document, if available.

Ink is smearing

Check print settings

zWhen you print documents that use much ink, allow more time to dry before handling the printouts. This is especially true for transparencies. In the printer driver, select the Best print quality, also increase the ink drying time and reduce the ink saturation using the ink volume under the advanced features (Windows) or ink features (Mac OS) in the printer software. However, note that decreasing ink saturation might give printouts a “washed-out” quality.

zColor documents that have rich, blended colors can wrinkle or smear when printed using the Best print quality. Try using the other print mode to reduce ink, or use HP Premium Paper designed for printing vivid color documents. See Changing print settings.

Check the media type

Some types of media do not accept ink well, ink will dry more slowly and smearing may occur. See Selecting print media.

Check the margin settings

If you are using a computer running Windows, make sure the option to minimize margins is not selected.
