16.5 Detection of Paper Jam
16.5.1 Feed section jams
[1] Aligning sensor non-arrival jam
1) Up to aligning sensor ON from start of feed from the tray in the one-sided and double-sided modes
The number of pulses equivalent to 15X the distance from the original set position to the aligning
sensor ON position is set as the jam pulse.
This is set when feed from the tray is started.
[2] Timing sensor non-arrival jam
1) Up to timing sensor from start of transport after aligning in the one-sided and double-sided modes
The number of pulses equivalent to 4X the distance from the aligning roller nip position to the timing
sensor ON position is set as the jam pulse.
This is set when transport by the aligning roller after original aligning is started.
[3] Aligning sensor accumulation jam
1) Up to aligning sensor OFF after start of transport from the initial alignment position in the one-sided
and double-sided modes
The number of pulses equivalent to twice the distance from the aligning sensor to the trailing edge of
the original when the longest original (LD) is standing by at the initial alignment position is set as the
jam pulse.
This is set when transport from the initial alignment position is started.
[4] Timing sensor accumulation jam
1) Up to timing sensor OFF from aligning sensor OFF
The number of pulses equivalent to twice the distance from the aligning OFF position to the timing
sensor OFF position is set as the jam pulse.
16.5.2 Transport section jams
[1] Turn guide sensor non-arrival jam
1) From timing sensor OFF to exit sensor ON when making the first copy (in all modes)
The number of pulses equivalent to twice the distance from the leading edge position of the original
at the point when the trailing edge of the original has passed the timing sensor to the exit sensor ON
position when the shortest original (personal check) has been fed is set as the jam pulse.
This is set at the point when the trailing edge of the original has passed the timing sensor when the
first copy is made.
2) From exit sensor OFF for the output original to exit sensor ON for the next original in the one-sided
mode
The number of pulses equivalent to twice the interval between originals when the shortest original
(personal check) is being fed by normal feed in the one-sided mode is set as the jam pulse.
This is set at the point when the trailing edge of the output original has passed the exit sensor in the
one-sided mode.
