The excessive jam alarm automatically notifies the service station when the
machine?s scanner or printer frequently has jam problems.
Each type of jam has three counters allocated to it (JAM, NO-JAM1, NO-
JAM2). Each of these counters has a threshold value (CALL, DEC, and CLR
respectively; these can be adjusted.) The machine uses these counters to
monitor jams as follows.
Each time a jam occu The Jrs: AM counter is increased by 1, and NO-JAM1
and NO-JAM2 are both set to zero. When JAM reaches CALL (6 by default),
the machine sends an Auto Service Report with a System Parameter List.
If a sheet of paper is fed without a jam occur NO-JAM1 and ing: NO-JAM2
are both incremented by 1. When NO-JAM1 reaches DEC (16 by default),
NO-JAM1 is set to zero, and JAM is decremented by 1. When NO-JAM2
reaches CLR (48 by default), NO-JAM2 and JAM are both reset to zero.
The CALL, DEC, and CLR thresholds can be adjusted for each type of jam
by rewriting RAM data. The addresses of these thresholds are given on the
next page.
