Nip Band Check Fusing Nip Band Check
1109
This SP sets the machine in the nip band width check mode. The nip width should
be 7 mm. You can increase it by changing the position of the pressure springs
(there are two positions only). If you cannot adjust to the correct value, replace
the pressure roller.
[*0=Off, 1=On]
Important! After checking the nip band width, switch off SP1109. If this SP
remains on, this will cause paper to jam in the fusing unit (SC559).
1111* Switchback Timing Paper Reverse Timing Duplex
[+5 ~ –5 / 0 mm / 1 mm step]
Adjusts the reverse timing of paper in the duplex unit (stopping the rotation of the
reverse roller after the trailing edge of the paper passes the duplex entrance
sensor).
Adjust the timing if paper frequently jams at the inverter gate in the duplex unit.
Fusing Jam SC Set
1159
This SP setting determines whether SC559 is issued after three paper late jams
occur in the fusing unit. After this SP code is turned on, a counter monitors the
number of paper late jams that occur in the fusing unit. After the 3rd occurrence of
a fusing jam, SP559 is issued and the machine cannot be used until the service
technician releases the error.
Note: Switching the machine off/on does not reset this jam counter. The counter
is reset after the cause of the jam has been removed and a sheet of paper
successfully passes the fusing exit sensor.
