Running a Job
Switch on the letter opener (I/O switch on rear side of unit).
Sort out any unsuitable pieces, i.e. plastic bags and letters
that are thicker than 4mm, or made from synthetic materials.
Tap the stack of letters (address field facing you and flap
facing up) on a flat surface several times in order to line up
the lower edges. This ensures that the contents slide down
inside the envelope and are not damaged when the
envelopes are slit open.
Turn the stack of envelopes upside down (address field
facing you but flap facing downwards). Loosen up the stack
just enough so that the top of each envelope rests on the
letter supporting surface.
* Be sure not to tap the stack again. *
Insert the prepared stack of envelopes between the
transport rollers and the pressure arm.
Press the green button to start processing.
Press the red button when all envelopes have been opened
and to stop the system.
Envelopes do not have to be sorted according to size, but they
should be arranged to face in one direction. To improve the
machine efficiency, large envelopes should be placed behind the
smaller ones in the letter opener.
In case large envelopes need to be opened:
Slide out and unfold the extension arm, as shown below.
Place the envelopes in landscape mode.

Safety
Before using your letter opener, please read this document and keep it near the machine as a
reference.
The letter opener complies with standard safety regulations for office equipment of this type. Before
operating it, read the following tips to assure safe operation:
Carefully follow the instructions for installation and operation of the letter opener.
Connect the letter opener to a grounded single-phase power outlet.
All maintenance and repair must be done by an authorized Formax service technician. Failure to
observe this rule will void your warranty.
Do not use water or benzene to clean your letter opener.
Avoid operating the letter opener without any envelopes in it. This will reduce the lifetime of the
machine.
The letter opener does not
feed envelopes into the cutting
unit.
Apply a slight amount of pressure to the pressure arm or stack of
envelopes until the envelopes are fed again one by one.
Letters are jammed in the
cutting unit.
1. Remove the stack of letters, which are not jammed, from the
feeder. Apart from the envelope that is jammed, pull the remaining
envelopes out of the cutting unit.
2. Then, pull the jammed envelope out of the cutting unit in the
direction of transport (see illustration).
Letters are not opened
properly.
Contact your authorized Formax dealer.
NOTE: Under no circumstances should you use anything such as a pair of scissors to remove any bits
of paper from the cutting unit.
To keep the unit in peak operating condition, periodically clean the feed rollers with a moistened cloth.
