Rev. 12/99
Description of Modification
•
Dirty Background: There is a
tendency for a 'dirty' background
or leading edge to develop after
the machine has not been used
for a long while. There is also a
tendency for increased image
density.
These tendencies are due to the
decreased turboelectric charge
of the Toner.
•
The initial machine warm-up
operations stop if one or more of
the doors to the option units are
open (e.g.1 bin tray, finisher).
The machine warm-up does not
restart after closing the doors.
•
When in user code mode, after
entering the power save mode
and then exiting, the counter
does not count the number of
copies the user makes.
•
Using the Norwegian Language,
when the machine should
display 'Copying will start after
warm up' in Norwegian, it is
displayed in French.
⇒
Conditions:
•
The toner collection bottle
becomes full with toner, causing
toner to spill out.
Countermeasure:
Shortening of the time that the
transfer belt is in contact with
the drum.
•
The default value for recovery
time for low-power mode has
been changed from 30 to 20 sec
(Machine temp. 145° to 157°C).
Since recovery starts at a higher
temperature, the machine has
more leeway in attaining ready
status.
•
Occasional occurrence of
SC542 after the power is turned
on in cold conditions.
Countermeasure:
Change in the timing of the
detection of the fusing
temperature. 35CPM machines:
from 125 to 135 sec.
45CPM machines: from 125 to
145 sec.
