Discover the key features of HP fax machines

• Universal compatibility
  Fax recipients won’t struggle with various versions of different applications, such as Windows, Acrobat, or Flash.
• Real-time results
  Faxing offers the comfort of immediately knowing whether or not your message was received.
• Simple signatures
  Avoid the hassle of obtaining or returning a signature. Faxing allows the easy transfer of signed documents (such as contracts) between two or more parties.
• Hard copy friendly
  Faxing is a fast, easy way to share hard copy data, and lets you skip the extra step of scanning.

Insert paper into the ADF (as shown here on the HP Officejet Pro L7590 All-in-One) to avoid manually inserting each page.

Use the fax broadcasting feature to quickly send the same fax to numerous locations.

Understanding the features and terminology associated with your HP fax machine will help you take full advantage of its capabilities.

• Automatic document feeder (ADF): Quickly feeds in paper so that you don’t have to manually insert each page. Allows convenient, unattended faxing.
• Junk fax blocking: Saves ink and paper by allowing your fax machine to block unwanted faxes from specific numbers that appear on caller ID (referred to as junk fax numbers).
• Auto fax reduction: Automatically reduces a fax to fit onto one page (if not possible, or if you turn this feature off, the extra information is then printed onto a second page). Automatic reduction is useful when you receive a legal-size fax, but have letter-size paper loaded.
• Fax broadcasting: Allows you to send the same fax to numerous numbers simultaneously. This feature can help you save time when sending newsletters, press, releases, or business price lists.
• Fax memory: The number of incoming or outgoing pages that your fax machine can digitally store. For more information, check out Fax Memory: How much do you need?
• Queue: Faxes that are being processed (outgoing and ingoing) are stored in a queue, or line. You can even scan multiple outgoing faxes straight to a queue (even while transmitting others), where they will be stored and sent in succession.  
• Phone features: Some fax machines offer advanced phone messaging capabilities, such as speakerphone and one-touch dialing.
• Polling: When a fax machine polls to receive, it requests a specific fax from another fax machine’s queue. Conversely, when a fax machine has the ability to be polled, you can scan a document into your fax’s queue for other parties to retrieve at their convenience (for example, when their calling rates are lower).
• Distinctive ring detection: If you have multiple telephone numbers on a single line, you can assign a specific ring pattern to each. When the phone rings, the distinctive ring detection feature then detects these patterns and identifies what type of call it is (for example, fax-specific, business, or personal).
