Q:
Why is a digital copier better than an analog copier? A: Digital copiers have some key advantages over analog ones. An analog copier is also known as a "light lens" copier. This essentially means that the copier takes a picture of the original and transfers that image onto a blank piece of paper. If you want 20 copies of the original, the copier has to take a picture of your original 20 times. An advantage digital copiers have over analog is their compatibility with other pieces of office equipment. Some digital copiers combine the functions of a network printer and a facsimile machine into one unit. This means that the same glass onto which a person places a document for copying can be used for document faxing. That can save the extra step of copying a page from a book and then faxing the copy. For incoming faxes, the copier stores the fax, allowing people to print out only those faxes they want to print. In a digital copier, the machine scans the original image, stores it into memory and retrieves the image from the memory to make the copies. You scan the original document one time, and walk away from the machine as the copies are being made. The digital copiers are now better than analog in terms of reliability and downtime especially since the paper path through the copier has been shortened so there is less chance of a paper jam. Digitals have about 200 internal parts and the analog copiers have about 2,000. The lower number of parts that can move means a lower number of parts that can break. If a digital copier is hooked into a computer network, other network users (employees) can print copies of their own documents to the copier, and all the steps of setting up a print job can be performed from each employee's desktop computer. --
