• Classification 4 indicates the default value in the new fixing pressure and fixing temperature table.
• The paper weight range which does not meet the specification, from 160 to 180 or from 221 to 300, can be set. However the
picking, feeding and the image quality are not given guarantee.
B) Increase of changing range for fixing pressure adjusted value of envelops.
The changing range for the adjusted value table which is selected with User Mode [Adjust fixing pressure] is increased to make
the impress of envelop difficult to appear.
As the default value is changed from [-1] to [-3], the state of the impress will be improved gradually. On the other hand, if the
image has generous amount of toner deposit, it leads poor fixing capacity by changing the adjusted values.
Adjust Fixing Pressure Recommended conditions of use Degree of improvement for the impress
-1 Image with small amount of toner deposit.
(Image with small amount of solid parts) Slightly improved
-2 Image with small amount of toner deposit.
(Image with small amount of solid parts) Almost no impress
-3 Text image No impress

The following sample indicates the case of adjusted values of fixing pressure for an envelope whose width is 130 mm or less and
the weight is from 181 to 220 (g/m2).
[A] line in the table shows previous adjusted values and [B] line indicates new adjusted values.
The changing range of new adjusted values is increased compared with the changing range of previous adjusted values.

The following new table of fixing pressure and fixing temperature for envelopes also includes the above-mentioned 2 new controls.
• Classification 4 in the table indicates the default value.
• The unit of paper weight is g/m2.
• P rows in the table show the setting values of fixing pressure. The numeric value means the number of pulse which drives
the pressure motor from its home position. The bigger the numeric value is, the greater the pressure is.
• Setting table of fixing pressure can be selected with User Mode [Adjust fixing pressure] (+1,0,-1,-2,-3). The default value is
[0].
• The fixing temperature can be fine-tuned with User Mode [Adjust Gloss/Fine Black]. Adjustable range: -2,-1, 0, +1, +2,
Changing range: 5 degrees C, High end: 200 degrees C. (When it is over 200 degrees C, it should be taken as 200 degrees
