[6] Tray spring pressure adjustment
Caution: Tray spring pressure adjustment must
be performed when no feed or double
feed of paper occurs. Tray spring
pressure may be affected by the type
of paper used or the operating envi-
ronment (under low temperature con-
ditions, no feed of paper tends to
occur. Under high temperature condi-
tions, double feed of paper tends to
occur). Excessive adjustment of tray
spring pressure may exacerbate the
problem. Take care.
