Setup, Compatibility & Care
To ensure optimal performance, verify that your mailing machine supports the 162 x 238mm size format. When loading the machine, fan the envelopes slightly before placing them into the feeder to ensure smooth separation.
For care, store these envelopes in a cool, dry place. Humidity can cause the gummed adhesive to activate prematurely or the paper to warp, which may lead to jams in your mailing equipment. If your machine features adjustable guides, set them firmly against the edges of the stack to maintain accurate feeding.
