Neopost IS420 Ink Cartridge Recycling Service

Buying original Neopost IS420 franking ink can be expensive for businesses, so many are looking for a cheaper alternative. Mailcoms offers its own refill and recycle service, and one cartridge we can refill is the Neopost IS420 ink cartridge. Refilling with us costs considerably less than buying an original cartridge directly from Neopost, helping your business save money.
Mailcoms was the first company in the UK to offer refilling and recycling of franking machine ink cartridges. Our own-brand ink has been approved by Royal Mail since 2011, and we are one of only two companies in the UK to have our own brand of franking ink approved by Royal Mail.
The Neopost IS420 Ink Cartridge Recycling Service involves us refilling your empty cartridges using our own Royal Mail approved RED or SMART BLUE franking ink. This means the ink has been thoroughly tested by Royal Mail to ensure readability and compatibility across a wide range of models, including the IS420 postage machine.
You can even refill and recycle your Neopost IS420 RED ink cartridge into a new SMART BLUE ink for the IS420 smart franking machine.
This service saves you money and is better for the environment than buying original products. We refill your empty ink cartridge and send it back to you within 48 hours of receiving your empty IS420 cartridge. As our ink is compatible with the IS420 franking machine, the refilled cartridge is guaranteed to last as long as any original cartridge bought directly from Neopost or alternative suppliers.
To ensure the Neopost IS420 ink cartridge is compatible and functioning, we personally test the refilled cartridge and send you a copy of the impression. This shows you what the new franking impression will look like in your IS420 franking machine, for your own peace of mind that the recycling service works for you.
