I've got a wireless 4500 that the auto feed for faxes gives me an error of fax send off. single pages faxed from glass work fine.

Directly from HP's manual on this printer:

Send a basic fax

You can easily send a single- or multiple-page black-and-white fax by using the

control panel, as described here. If you want to send a color or photo fax, see the

onscreen HP Image Zone Help.

Note If you need printed confirmation that your faxes were successfully sent,

enable fax confirmation before sending any faxes. For more information, see

Print fax confirmation reports.

Tip You can also send a fax manually from a phone or by using monitor

dialing. These features allow you to control the pace of your dialing. They are

also useful when you want to use a calling card to charge the call and you

need to respond to tone prompts while dialing. For more information, see Send

a fax manually from a phone or Send a fax using monitor dialing.

1. Load your originals, with the print side up, into the document feeder tray. If you

are sending a single-page fax, such as a photograph, you can also load your

original on the glass.

Note If you are sending a multiple-page fax, you must load the originals

in the document feeder tray. You cannot fax a multiple-page document

from the glass.

2. Press Fax.

Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page. If this is the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

Try reading these:

General fax problems Issue Cause Solution The document stops feeding in the middle of faxing. The maximum length of a page that can be loaded is 381 mm (15 inches). Faxing of a longer page stops at 381 mm (15 inches). If no jam exists and less than one minute has elapsed, wait a moment before press Cancel . If a jam exists, remove the media. If the item is too small, it can jam inside the automatic document feeder (ADF).

(HP LaserJet 3015 all-in-one) The minimum paper size for the ADF is 74 x 105 mm (2.9 x 4 inches).

(HP LaserJet 3030 all-in-one and HP LaserJet 3380 all-in-one) The minimum page size for the ADF is 127 x 127 mm (5 x 5 inches). If a jam exists, remove the media. The fax activity logs or fax call reports are printing at inappropriate times. The fax activity log or fax call reports settings are not correct. Print a configuration report and check when the reports print. Set the appropriate log or report printing times through the control panel or the HP Toolbox. The volume for sounds that the device emits is too loud or too soft. The volume setting needs to be adjusted. Set the appropriate sound volume settings through the control panel. Fax send troubleshooting Use the information in the following table to solve problems that might occur when sending faxes: Issue Cause Solution Faxes stop during sending. The fax machine to which the fax is being sent might be malfunctioning. Try sending to another fax machine. The telephone might not be working. Do one of the following:

• Turn up the volume on the device, and then press Fax/Send on the control panel. If a dial tone is heard, the telephone line is working.
• Disconnect the device from the jack in the wall, and then connect a telephone to the jack. Try to make a telephone call to make sure that the telephone line is working.

A communication error might be interrupting the fax job. Change the redial-on-communication-error setting to On.

See the electronic User Guide on the CD-ROM that shipped with the product. The device is receiving faxes but is not sending them. If the device is on a PBX system, the PBX system might be generating a dial tone that the device cannot detect. Disable the detect-dial-tone setting.

See the electronic User Guide on the CD-ROM that shipped with the product. A poor telephone connection might exist. Try again later. The fax machine to which the unit is sending to might be malfunctioning. Try sending to another fax machine. The telephone line might not be working. Do one of the following:

• Turn up the volume on the device, and then press Fax/Send on the control panel. If a dial tone is heard, the telephone line is working.
• Disconnect the device from the jack in the wall, and then connect a telephone to the jack. Try to make a telephone call to make sure that the telephone line is working.

Outgoing fax calls continue to be dialed. The device automatically redials a fax number if the redial options are set to On. Press Cancel to stop the redials while the device is dialing.

To cancel a pending fax job, see "Canceling a fax job" in the electronic Users' Guide on the product CD-ROM.

See "Changing the redial settings" in the electronic Users' Guide on the product CD-ROM. Faxes that are sent are not arriving at the receiving fax machine. The receiving fax machine might be off or might have an error condition, such as being out of paper. Call the recipient to make sure that the fax machine is on and ready to receive faxes. The originals might be incorrectly loaded. Make sure that the original documents are correctly loaded into the automatic document feeder (ADF) input tray or flatbed scanner (not available with the HP LaserJet 3015 all-in-one). A fax might be in memory because it is waiting to redial a busy number, other jobs that are ahead of it are waiting to be sent, or the fax is set up for a delayed send. If a fax job is in memory for any of these reasons, an entry for the job appears in the fax log. Print a fax activity log and check the Status column for jobs that show a Pending designation. All of the numbers of a long fax number cannot be dialed. The maximum number of digits of characters that can be entered into a fax number is 50. Try manually dialing the fax number. Faxes that are sent include a block of gray shading at the end of each page. The original may be on the flatbed scanner (HP LaserJet 3030 all-in-one and HP LaserJet 3380 all-in-one only), with the glass-fax size set incorrectly. Make sure the setting is correct. See "Changing the default glass-size setting" in the electronic Users' Guide on the product CD-ROM. Faxes that are sent have data missing from the end of each page. The original may be on the flatbed scanner (HP LaserJet 3030 all-in-one and HP LaserJet 3380 all-in-one only), with the glass-fax size set incorrectly. Make sure the setting is correct.
