Remarks
Use it after supplying toner at time of installation.
Use it to adjust the fixing film drive roller
pressure for the upper fixing unit. (See p. 10-
28.) Fix the fixing tension roller and cause the
fixing film to rotate idly. The ON period of the
fixing film sensor is indicated by the copy
count indicator, and the film position is
indicated by the copy density indicator.
Another press on the Start key checks the
position of the fixing film automatically.
Execute the mode when you have replaced
the fixing film or the upper fixing unit to return
the fixing film to its appropriate position. (See
p. 10-28.) The film stops as soon as it
reaches the appropriate position automatically.
The position of the film in travel is indicated by
the copy density indicator.
Use tit to check the nip or when adjusting the
lower fixing roller. (See p. 10-30.)
The fixing film stops when it reaches the
appropriate position or when 30 sec has
passed. The position of the film in travel is
indicated by the copy density indicator, and
the fixing film ON period is indicated by the
copy count indicator. The position is normal if
the copy density indicator indicates ‘5’ when
the film stops; otherwise, check the fixing film
and the tension roller. If the fixing film
becomes displaced and E007 is indicated, try
this mode. (This will prove to be highly useful
if displacement occurs because of a minor
accident.)
A press on the Start key keeps the lamp on
after about 1.5 sec.
