SYMPTOM
JAM170 (SR5020 booklet unit exit sensor detects a paper jam) occurs when staple jobs
are run alternately between two different paper types that have the same width (main scan
direction) but different length (sub scan direction), for example, A3 and A4.
Occurrence rate: 100%
JAM170 occurs when all of the following conditions are met:
1) Staple jobs of different paper sizes are run continuously in printer mode.
2) The two paper types have the same width (main scan) but different length (sub scan).
3) The same stapling position is applied to the alternating jobs.
CAUSE
Firmware bug; when the paper changes, the system is not given enough time to move the
leading edge stopper (located in the booklet finisher) to the proper position.
SOLUTION
Firmware fix (release schedule TBD)
WORKAROUND
Until the fixed firmware becomes available, work around the problem by carrying out either
of the following procedures:
1) Run the jobs separately by paper size.
2) Specify a different stapling position for each paper size.
