Cause: The glass of the HP All-in-One might be dirty.

Solution: If you are sending a fax from the glass, make a copy to check the quality of the printout. If the quality of the printout is poor, clean the glass.

To make a copy from the control panel

1.Make sure you have paper loaded in the input tray.

2.Load your original print side down on the right front corner of the glass or print side up in the document feeder tray.

If you use the document feeder tray, place the pages so that the top edge of the document goes in first.

3.Do one of the following:

Press Start Copy Black to initiate a black-and-white copy job.

Press Start Copy Color to initiate a color copy job.

NOTE: If you have a color original, pressing Start Copy Black produces a black-and-white copy of the color original, while pressing Start Copy Color produces a full-color copy of the color original.

To clean the glass

1.Turn off the HP All-in-One, and raise the lid.

2.Clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive glass cleaner.

CAUTION: Do not use abrasives, acetone, benzene, or carbon tetrachloride on the glass, since they can damage it. Do not place or spray liquid directly on the glass. The liquid might seep under the glass and damage the device.

3.Dry the glass with a dry, soft, lint-free cloth to prevent spotting.

4.Turn on the HP All-in-One.

Cause: The receiving fax machine is having problems.

Solution: To check this, try calling the fax number from a telephone and listen for fax tones. If you cannot hear fax tones, the receiving fax might not be turned on or connected, or a voice mail service could be interfering with the recipient's phone line. You can also ask the recipient to check the receiving fax machine for any problems.

Cause: The Lighter / Darker setting might be set too light. If you are sending a faded, washed out, or handwritten fax, or a document with a watermark (such as a red seal or stamp), you can change the Lighter / Darker setting to send the fax darker than the original.
