If you go to Control Panel and open your Printers, you will probably find that this printer has installed itself twice...one is listed as a FAX PRINTER and the other IS NOT . Select the one that IS NOT listed as a fax, right-click it and select it as your default printer. If you ever need to send a FAX, then you'll need to PRINT to the FAX PRINTER.

I have the printer manual - thanks ! Ravencajun - the printer software was reinstalled several times on the new system - it seems the 'mother organization' has a few added restrictions on XP which is giving IS some fits on HP printers - after 2 days of fiddling, the tech changed the port that XP assigned and the fax out is now working! I was sweating bullets there for a while since we did not extend the warranty on the printer after last year, everything had been working fine for the year prior and we had had a couple of parts replaced, so we decided to chance it and not pay $200+ per year for the warranty. There's a part of me that wishes we had now since I found out HP won't even talk to me unless we pay them $400+ up front for tech support, then if they cannot solve your problem they "credit' you the fee towards a new printer. My tech agreed that adding the fax modem to allow me to fax from WORD would be a decent workaround - but it's nice to have the printer fully functional. It's funny, but when we got this all in one - many people in the organization told us that "you know if one part doesn't work, none of it works", well I know now that isn't true. Still and all - it's a great device and it allows me to churn out the work of 2 people, I wouldn't hesitate to get another!

Have you checked 'System preferences' to see if the fax modem is listed and the drivers show as installed correctly?

I have used eFax for years for my business. I have a premium account, which gives me a unique phone number so people can fax back, but they're free for up to 10 outgoing faxes a month, I think. As an aside - fax is an outdated method of transmitting document, and I *HATE* it that I have to maintain a fax line, but I do! Here is a link that might be useful: eFax Free
