❑For color or complex grayscale images, turn on MicroWeave and turn off High Speed.

❑Use a higher-quality paper.

❑For monochrome printing, check that Monochrome is selected.

❑Make sure the Media Type setting matches the type of paper loaded in the printer.

Other problems may be caused by an incorrect driver setting. If you’re printing a scanned image, check the scanner software settings.

If print quality does not improve, see the following specific items.

Printed output is not what you expect or is faint or blurred.

Clean one or both print heads as described in Chapter 5.

Replace one or both ink cartridges.

Make sure MicroWeave is on and High Speed is off.

Use a higher quality paper. Also, check that the Media Type setting in the driver is selected for the type of paper loaded. If you are using 720-dpi resolution, be sure to load special coated 720-dpi paper or High Quality Glossy paper. Always use this special paper when printing at 720 dpi.

Check that the paper thickness lever is set correctly for the type of paper. (See “Loading envelopes” in Chapter 2 for more information.) Faint printouts can result if you print on plain paper when the paper thickness lever is set for thick paper.

Check whether your paper is moist or damp. Ink jet printers are sensitive to moisture absorbed by paper. Do not store paper in damp or humid places.
