Answer:
a. scanner
Step-by-step explanation:
Photocopiers can be configured with a scanner that can transmit the images of documents to computers. Here's some information about scanners and their role in photocopiers:
1. Scanner function: A scanner is a device that captures and digitizes images or documents. It uses light sensors to convert physical documents or images into digital files that can be stored, edited, or transmitted electronically.
2. Integration with photocopiers: Many modern photocopiers are equipped with built-in scanners. This allows users to place a document on the scanner glass or feed it through an automatic document feeder (ADF), and the photocopier can scan the document and make copies of it.
3. Transmitting images to computers: When a photocopier is configured with a scanner, the scanned images can be transmitted to computers through various methods. This can include direct connections via USB or Ethernet, or wireless connections such as Wi-Fi or Bluetooth.
4. Benefits of scanning: Scanning documents using a photocopier scanner offers several advantages. It allows for easy archiving and digital storage of documents, eliminates the need for physical copies, and enables easy sharing or emailing of scanned documents.
While fax machines and modems can also transmit documents electronically, they are not typically associated with the scanning functionality found in photocopiers. Fax machines are specifically designed for transmitting facsimile (fax) messages over telephone lines, while modems are used to establish internet connections. Printers, on the other hand, are output devices that produce physical copies of digital documents or images.
In summary, scanners are the component of a photocopier that can capture and digitize document images, allowing for electronic transmission to computers.
