Which equipment is essential for a Mail Clerk for processing outgoing mail?

The essential equipment for a Mail Clerk when processing outgoing mail includes stamping machines and weight scales. Stamping machines are crucial because they allow the mail clerk to apply postage to letters and packages accurately, ensuring that outgoing mail has the correct postage required for delivery. This is an important part of ensuring timely and correct mail delivery.

Weight scales play an important role as well, as they enable the mail clerk to weigh packages to determine the appropriate postage based on weight. Different mail services have varying costs depending on the weight of the parcel, so having a scale helps ensure that the clerk can calculate the right postage. This prevents issues such as insufficient postage, which could delay delivery or result in the return of the mail.

The other options, while they may serve useful purposes in a mail handling environment, do not address the specific needs of processing outgoing mail as directly as stamping machines and weight scales do. For example, sorting trays are primarily used for organizing incoming mail rather than preparing outgoing items. Personal computers may assist with record-keeping or displaying information but do not directly impact the physical processing of mail. Lastly, file cabinets are more suited for storage of documents rather than actively processing mail, making them less relevant in this context.
