Plain Paper Fax and Copier (Thermal Transfer) With the ability to make multiple copies at up to 4 pages per minute, as well as enlarge, reduce and collate, this unit is not just a fax machine, but a true home/life office command center. This fax machine is Caller ID compatible so you can see who is calling before answering. With two lines of up to 16 characters available, you are able to see the name and number of your incoming callers. You can even display and print a list of Caller ID activity. All of this adds up to a great timesaving feature for both business and personal use. Connecting an optional, external answering device lets you receive voice and fax messages on one phone line. With automatic fax/phone switching, this unit actually distinguishes between fax and voice calls, eliminating the need for an extra phone line. The navigator key lets you easily access menu operations like the phone directory and dialer, plus Caller ID memory. It also simplifies programming of the unit.
