ENWW Pickup/feed system 189
3 Fuser delay jam: When the paper does not reach the fuser delivery paper sensor (PS7) within
the allotted amount of time after paper is fed from the registration roller, the CPU judges it a
fuser delay jam.
4 Fuser stationary jam: When the paper does not pass the fuser delivery paper sensor (PS7)
within the allotted amount of time after paper has reached the fuser delivery paper sensor
(PS7), the CPU judges it a fuser stationary jam.
5 Delivery delay jam: When the paper does not pass the sensor through within the allotted
amount of time after paper has reached the fuser delivery paper sensor (PS7), the CPU judges
it a delivery delay jam.
6 Delivery stationary jam: When the paper does not reach the face-down paper sensor (PS8)
within the allotted amount of time after paper has reached the fuser delivery paper sensor
(PS7), the CPU judges it a delivery stationary jam.
7 Duplexing feed delay jam (3700 printer only): When the paper does not reach the reversed
paper sensor (PS9) within the allotted amount of time after the delivery motor has started
rotating counter-clockwise, the CPU judges it a duplexing feed delay jam.
8 Duplexing feed stationary jam (3700 printer only): When the paper does not pass the
sensor within the allotted amount of time since paper has reached the reversed paper sensor
(PS9), the CPU judges it a duplexing feed stationary jam.
9 Duplexing pickup delay jam (3700 printer only): When the paper does not reach the
duplexing feed paper sensor (PS10) within the allotted amount of time after paper has reached
the reversed paper sensor, the CPU judges it a duplexing pickup delay jam.
10 Duplexing pickup stationary jam (3700 printer only): When the paper does not pass the
sensor within the allotted amount of time since paper reached the duplexing feed paper sensor
(PS10), the CPU judges it a duplexing pickup stationary jam.
11 Door open jam: When the front cover is opened during printing operation, the CPU judges it a
door open jam.
12. Residual paper jam: The CPU judges a residual paper jam for two conditions:
• When paper is detected by the registration paper sensor (PS4), the fuser front paper sensor
(PS6), or the fuser delivery paper sensor (PS7), the CPU judges it the residual paper jam.
• When paper is detected by the fuser front paper sensor (PS6) or the fuser delivery paper
sensor (PS7), the CPU judges it the residual paper jam.
If paper is detected by sensors other than the PS6 and PS7, the DC controller delivers the
paper automatically.
Note The automatic paper delivery system delivers a residual paper automatically, if possible, when the
power is turned on or the printer starts printing. The CPU sends an automatic paper delivery request
to the formatter when it detects a residual paper that can be possibly delivered automatically. Upon
receipt of a command for an automatic delivery from the formatter, the CPU drives each motor and
delivers such paper out of the printer.
