As long as the device is connected to a telephone line, the machine allows you transmit documents to someone or from office to office. The transactions may be done as little as one minute. In fact due to the advance technology of every business, sometimes it becomes impossible to do business without fax machines.Dont you know that fax machines are things of the fast? It was invented somewhere in mid 1843 but till then the use has not been found to be useful. The first machine is made of drum. You have to manually rotate the drum to send the document. This may sound funny but that was true. Along with the drum is a small photo sensor, a lens and a light.Today gone are the days of drums to send documents and due to advance technology it becomes faster today, though the mechanics are still the same, difference are as follows:· The receiving fax machines has something like sensor where it can read the document on the paper and through the paper feed from the receiver, the sensor can transfer the words.· Fax machines can encode what it has been detected from the sensor, through a telephone line. The black dotted are the ones that the sensor can detect. For example if you are going to fax a hand written letter, you must use black ink so that the sensor can copy it well via a telephone line.· It is the reason why when you received the fax documents; there are lots of dotted marks.A standard fax machines used on offices are known as group 3 facsimile. It designates fax machines as follows:· It communicates well to all groups 3 facsimile.· It has a good resolution which can read up to 203 pixels per inch document.· The vertical resolution comes in 3 different pixels.· The data receive is about 14,500 bits / second, that in busy lines the data receive can fall back to 12, 000 bits / second. However if the line is staggering it can fall to 2, 000 bits / second. It is the reason why sometimes when you receive the fax document, the letters are not clear and sometimes lacking.All fax machines have photo diodes where it control the sensors received per inch per pixels. To get a clearer review of the document, the paper goes through a small lens so that the sensor can read it clearly.Before the papers go through the light, it must travel first to a telephone line. Both lines from the receiver and the sender should be opened and should have communicated before faxing is done. Otherwise the sensor cannot read the document even of the papers had gone through the light lens. Until such then, there will be no proper decoding of the document to be transferred to the other line.
