Print-quality issues

General advice

When you have any print-quality problem:

●To achieve the best performance from your printer, use only genuine HP supplies and accessories, whose reliability and performance have been thoroughly tested to give trouble-free performance and best-quality prints. For details of recommended substrates, see the User's guide.

●Check that the substrate type selected in the HP Internal Print Server is the same as the substrate type loaded into the printer.

CAUTION: If you have the wrong substrate type selected, you could experience poor print quality and incorrect colors, and perhaps even damage to the printheads.

●Check that your substrate has been color-calibrated.

●Check that you are using the correct ICC profile for your substrate and print mode.

●Check that you are using the most appropriate print-quality settings for your purposes (see the User's guide).

●Check that the environmental conditions (temperature, humidity) are in the recommended range (see the User's guide).

●Check that the printheads have been aligned.

●Check whether there are any outstanding printer alerts.

●Avoid touching the substrate while printing is in progress.

Banding

Banding means that your printed image suffers from added horizontal lines as shown (the color of the lines may vary).
