Solution: If you did not load an original in the document feeder tray, or if the original is not pushed in far enough, you will be unable to send a fax manually. Load an original in the document feeder tray, or push the original farther into the tray. Once the HP All- in-One detects the original, a confirmation message appears on the display.

Pages of a fax I sent are missing

Cause: Two or more pages were fed through the document feeder tray at the same time.

Solution: Print a Last Transaction report to verify the number of pages that were sent. If two or more pages stuck together and were fed into the document feeder tray at the same time, the number of pages in the report would not match the actual number of pages. If the number of pages listed in the report does not match the actual number of pages, you might need to clean the separator pad in the automatic document feeder.

To print a Last Transaction report

1.Press Setup, and then press 2. This selects Print Report.

2.Press to select Last Transaction, and then press OK.

For more information on cleaning the separator pad, see Clean the automatic document feeder.

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. The memory of the receiving fax machine might be full or the fax machine might have run out of paper. You can ask the recipient to check the receiving fax machine for any problems.

Cause: The phone line connection is noisy. Phone lines with poor sound quality (noise) can cause faxing problems.

Solution: If the failure was due to noise on the phone line, contact the sender to have them resend the fax. The quality might be better when you try again. You can check the sound quality of the phone line by plugging a phone into the telephone wall jack and listening for static or other noise. If the problem persists, turn Error Correction Mode (ECM) off and contact your telephone company.

To change the ECM setting from the control panel

1.Press Setup.

2.Press 5, and then press 6.

This selects Advanced Fax Setup and then selects Error Correction Mode.

3.Press to select On or Off.

4.Press OK.
