Explanation
Copying back to back is an effective way to reduce the amount of paper used. By printing or copying on both sides of the paper, it allows for more content to fit on a single sheet, thus reducing the need for additional paper. This simple practice can significantly decrease paper consumption and contribute to environmental conservation efforts.

Explanation
PAT Testing stands for Portable Appliance Testing. It is a process of checking electrical appliances to ensure their safety and functionality. This testing involves a series of visual inspections and electrical tests to identify any potential hazards or faults in the appliances. By conducting PAT Testing, organizations can comply with safety regulations and protect their employees and customers from electrical accidents.

Explanation
A shredder is the correct answer because it is a piece of office equipment specifically designed to destroy documents by cutting them into small pieces. It is commonly used to maintain confidentiality and prevent sensitive information from being accessed or misused. The recycle bin is not a piece of office equipment used for destroying documents, but rather for temporarily storing files before they are permanently deleted. The fax machine is used for sending and receiving documents electronically, but it does not destroy them.

Explanation
Loading paper into the photocopier correctly is important to prevent jams. If the paper is not loaded properly, it can get stuck or misaligned, causing the photocopier to jam. This can disrupt workflow and waste time as the jam needs to be cleared before copying can resume. Therefore, ensuring that the paper is loaded correctly helps to prevent jams and maintain smooth operation of the photocopier.

Explanation
To send an exact copy of a document, you would use a fax machine. A fax machine scans the document and converts it into a digital image, which is then transmitted over telephone lines to the recipient's fax machine. The recipient's fax machine receives the digital image and prints out an exact copy of the document. This method ensures that the recipient receives an identical copy of the original document, making faxing a suitable option for transmitting important documents or contracts.

Explanation
A franking machine is a piece of equipment used to calculate and apply postage to mail items. It is commonly used in businesses and organizations to efficiently process large volumes of mail. The machine weighs the mail and calculates the appropriate postage based on the destination and size of the item. It then applies a franking mark or stamp to indicate that the postage has been paid. This eliminates the need for manual stamping and helps streamline the mailing process.
