When you lease a postage meter, companies will require you use a sealing solution in your postage meter. Companies do this to prevent corrosion of machine parts. While companies such as Pitney Bowes often market their own specific sealing solutions, you are not required to purchase a specific brand.
Machine Maintenance
Postage meter machines need sealing solution to prevent mold and corrosion. If sealing solution is not used, mold will begin to grow in the tank and tubing of your postage meter machine. The mold will clog the system and the system may require a replacement.
Keep your machine in great condition by making sure to use sealing solution. Consider saving on machine costs by purchasing compatible sealing solution at a fraction of the price of Pitney Bowes and large companies.
