Measures
In the System Menu, change
the media type of the cas-
sette to use to [Custom7] and
change the paper weight of
"Custom7" to
[Light].<br>Custom7 setting
for the thin paper use: This is
the mode to prevent the fuser
separation failure by reducing
the paper conveying speed
and lowering the fuser tem-
perature. (After changing this
setting, "Adjusting..." is dis-
played till the fuser tempera-
ture is lowered.)
Reinstall the fuser unit and
reconnect the connector.
Turn the fuser exit sensor on
and off manually and check
the indication at U031 [Fuser
Feed]. If the fuser exit sensor
does not properly operate,
clean and reattach it and rein-
sert the connector. If not
repaired, replace the fuser
unit.
Execute U033 [Branch Exit]
to check the feedshift guide
operation. If the guide does
not properly operate, reattach
the feedshift solenoid and
reinsert the connector. If not
repaired, replace it.
Execute U030 [Fuser]. If the
fuser motor does not properly
operate, reattach it and rein-
sert the connector. If not
repaired, replace it.
Check if the fuser motor
smoothly rotates by a hand.
Then, clean and reattach the
drive parts if necessary. If not
repaired, replace them.
