MailFinisher 4000
The Mailfinisher 4000 offers a highly intelligent inline Pressure Sealer solution. It eliminates the task of unloading forms from a laser printer and then loading them into the Pressure Sealer folder sealer. Inline solutions offer enhanced security when processing sensitive documents.
When looking at a standard offline pressure seal machine versus an in-line solution there are important aspects to consider. Contact John Barr, the InfoSeal pressure seal equipment specialist for help.
