Table 32. Leading Edge of Jammed Paper Is in Pickup/Transfer Area
Step Check Result Action
1 Try printing with
known-good paper. Does
the problem persist?
No Problem solved.
2 Try feeding the paper from
one of the other paper
sources. Does jamming still
occur?
No Go to Table 33, 34, 35, or 36, as
applicable.
3 Remove the toner car-
tridge, hold the green knob,
and lift the delivery guide.
Does the registration sen-
sor arm move back and
forth freely when you flick it
with your finger?
No Clear it if possible. If the arm is
snagged beyond repair, replace the
sensor holder assembly.
4 Check for obstructions,
especially beneath the
upper guide plate situated
between the pickup block
and the transfer roller. Are
there obstructions?
Yes Clear the obstructions.
5 Is the trailing edge of the
jammed paper about an
inch short of the registra-
tion sensor arm?
Yes If paper has jammed there, especially
if there is no sign of crumpling, there is
almost certainly a failure in the
delivery sensing system. Go to
Table 31.

maintain pickup
connectivity. You will be
taking measurements from
the solder side of the
pickup controller board.

the registration sensor arm.
Does the voltage measure
about 5 V (normal) and 0 V
(tripped)?
