Remove an envelope jam
For removing an envelope jam please follow these steps:
1. Switch off the machine and disconnect the power cord.
2. Open the top cover (see track cover on page 6)
3. Draw out the jammed envelopes to the direction of the receiving tray.
4. Close the cover carefully.
5. Re-connect the power cord.
Normally, envelope jams only occur when working with mixed envelope sizes. In
case of frequent jams you should pre-sort all envelopes according to their size and
thickness. Then process them with the letter opener separately.
NOTE: The track cover is connected to a safety switch. The letter opener doesn't run if
this cover hasn't been closed firmly.

Transport belts

If you hear the motor running but the transport belts don't move, most probably the
transport belts are broken or in a wrong position. In this case please contact the
manufacturer or dealer from which you bought the machine. They will check and repair
it.

Cleaning the transport belts

During operation the transport belts will get dirty and dusty after a while. Therefore, we
recommend to clean the belts regularly to make sure that your letter opener will
continue to work effectively and correctly.

Insufficient envelope opening

Under special circumstances it can happen that your envelopes are not opened
correclty. Most often this happens if working with the machine improperly or if the
transport belts are dirty.
Perhaps the cutting width is too small. Then correct it by turning the adjustment wheel
(from 0,5 up to 4 mm).
If your envelopes are not opened correctly despite all measurements taken, the cutting
blade might be damaged or not adjusted correctly. In this case please contact your the
manufacturer or dealer from that you bought the letter opener.
