The Samsung fax, phone and copier machine we have at home has been with us for the past 6 years. My husband bought it especially for home use since he does some of the paper office work at home and need to fax it somewhere. We used to have a separate land phone unit but we decided to just use this multi-function machine.
As a phone unit it has the usual volume adjustment which can be done via the led screen on top of it. It also has the usual redial button and a speaker phone function. These are features that can also be found in regular phone units though, but having a fax machine and a copier at the same time is a big plus.
This machine provides a laser fax function. It has a special feature of 5 second document scan when faxing. It also stores memory of all the documents received especially when the incoming fax were received and there was no paper on the tray. If incoming fax was received a note will be flashed on the screen reminding as well to put paper, and it will automatically print the faxed documents then.
The copier function has no special feature though, except that the document can be recopied zoomed in or zoomed out, which can also be found in other machine of similar type.
The only thing that I don't really like much about this machine is the paper tray attached at the front for incoming fax and recopied documents. The tray is not long enough to hold even the A4 size documents, thus causing them to drop on the floor.
Overall however, I am happy with this machine. I think it will still stay with me for several years unless I would decide to purchase a new model for a change.
