6.0 Operator’s Troubleshooting Guide
6.1. Envelopes jam in blade and do not exit letter opener.
Paper jamming in letter opening blade is most often due to more than one envelope
feeding into the cutting blade at once or envelope contents in the cutting area. Use the
following steps to clear a jam.
1. Unplug machine
2. Tilt up blade cover
3. Carefully remove any jammed envelopes from cutting blade.
Caution: Be very
careful, as the blade is very sharp.
4. When finished, run a single envelope through the letter opener and check its cut
width. This setting can move during a severe paper jam and may require re-
adjustment. See section
4.3
.
6.2. Envelopes fail to feed, machine runs
Failure to feed envelopes can be caused by several different reasons; they are listed in
declining order of likelihood:
1. Dirty feed belts. Clean with Martin-Yale
Rubber Roller Cleaner and Rejuvenator
.
2. Envelopes are too wide to feed. Review maximum envelope sizes listed on the front cover
of these instructions.
3. Feed belts are worn.
6.3 Machine does not run at all
1. Check that the opener is plugged into an active line
2. Examine blade cover, it should be fully down so as to activate its safety switch
3. Check that power cord is firmly inserted into the letter opener
4. Machine may be jammed to the point of non-running. See troubleshooting point 6.1.
5. Electrical Malfunction. Have the 1648 checked by a qualified technician.
6. Motor belt has fallen off of pulleys.
6.4 Envelope feeds through machine, but is not opened
1. Cut width is set too narrow, adjust to wider setting
2. Back up bearing needs adjusted, see section
5.3
.
3.
Cutting blade is dull. Replace or sharpen blade.
