Intelligent inserting with OMR reading

For your outgoing mail you need to prepare e.g

  • Invoices/reminders
  • Salary slips
  • Mailings with individual enclosures


And this, if any possible, automatically. Often, there is also the task to insert an individual number of sheets per envelope. The SI 4350 offers the best solution: This inserting machine is equipped with an OMR (Optical Mark Recognition) reading function by default.

  • Control codes printed on the documents are recognized by the inserting machine so that it collects and inserts an individual number of sheets per envelope reliably. 
  • Additionaly, postage optimisation and an individual feeding of enclosures is offered.


Optionally, the SI 4350 functions can even be extended, e.g. with:

  • Reading station for 2-D-code reading
  • Power stacker tray
  • Inline connection to a franking machine


Completely adapted to your organisation.
