How to use a franking machine in 5 quick steps

Do you regularly post letters or parcels through your business? Well, you could actually be spending more time and money than you need to be. This is where a franking machine can help. Whether you’re sending 5 or 500 letters, franking machines are designed to handle it all and make your life easier.

While it may look complicated initially, operating a franking machine is a simple process that will take mere minutes. Our guide will teach you how to use a franking machine in 5 quick and easy steps.

What is a Franking Machine?

A franking machine is designed to pay for postage in advance. Meaning you and your employees will never have to endure long waits at the post office again! The machine weighs the letters, provides an accurate postage and stamps them for proof. No matter the size of your company, this is an extremely convenient machine to have in your office – especially if you take trips to the post office often.

How to use a franking machine in 5 easy steps

1. Organise Your Letters and Parcels

If you’re posting a lot of letters it’s strongly advised you organise them before franking so the process can run smoothly and efficiently. Start by organising your items according to format – letter, large letter, small parcel and medium parcel. Each of these formats has specific size and weight restrictions so it’s important you categorise them correctly. 

You may also find it useful to organise your post by their destination, whether they’ll be sent within the UK or internationally. And, sort the 1st or 2nd class, Royal Mail Signed For or Special Delivery Guaranteed too. Organising your post thoroughly before franking lessens the risk of any errors later on and ensures a streamlined service.

2. Select the Product Type

Using either the touch screen or the keys on the franking machine choose the type of product you need from the available options. Most machines will keep the postage rate updated, but, we recommend always checking beforehand. You can add a return address or even a marketing message or slogan to make your letters stand out to whoever you’re sending them to.

3. Weigh Your Post

Most modern franking machines have integrated scales, so, once everything is organised, weigh each item to determine their correct postage. All you need to do is place the item on the scale, confirm the weight on the screen and the postage will be automatically calculated for you. 

Of course, it’s important to remember that every machine is different and some may even offer a stack weighing mode. This allows you to place all letters on the scale for the total weight, then removing the letters one-by-one to find out the postage. Make sure you read the instruction manual to discover the best way to weigh your post on the franking machine.

4. Insert Letters into the Machine

Feed your letters into the machine with the selected postage rate, making sure they’re facing upwards and a franking mark will be stamped onto the envelope. Some machines also allow you to stamp your company logo too for a more professional finish. If you choose a high-capacity machine, it’s likely you’ll be able to feed the letters in bundles to help speed up the process.

5. Prepare Mail for Post

When it comes to taking your franked mail to the post office, there are a few things you need to remember and prepare. Firstly, make sure the franking marks are clear, legible and in the right place (the top right-hand corner) to avoid any surcharges. Then, organise your franked mail into class type, size and destination and put them in separate franking postage bags. You can pick up extra postage bags from Royal Mail.

How to do recorded/signed for delivery on franking machine

It couldn’t be more seamless. As you’re popping your mail through the franking machine, just select either ‘special delivery’ or ‘recorded’ in the displayed options you’re given. The entire process is practically the same as 1st or 2nd class, except that this selected option will add the correct surcharge to ensure your parcel is prioritised for recorded or signed delivery.

If your franking machine doesn’t have these options set automatically, you’ll need to adjust the surcharge yourself by cross-checking the prices online and taking your parcel to the post office.

We’d recommend inquiring whether these features come with the franking machine you’re thinking of buying.
