DFDST-L2 1 Title Dirt detection level adjustment (upon job completion) during ADF use
Purpose of use, When used This item is used when black streaks caused by dirt have occurred or when users have filed complaints.
Adjust the dirt detection level in the dirt detection correction control which is exercised when jobs
have been completed.
Precautions for use Increase the value when dirt fails to be detected, resulting in black streaks. However, if the value is
increased too much, even small-sized dirt of the kind which does not appear on the image will also be
detected, and the cleaning instruction screen may appear frequently.
Reduce the value if users complain because the cleaning instruction screen which appears when dirt is
detected is displayed frequently. Conversely, if the value is reduced too much, black streaks may
appear on the images.
Settings and adjustment
ranges 0 to 255
When the value is reduced, it becomes harder for dirt to be detected.
When the value is increased, it becomes easier for even small-sized dirt to be detected.
When '0' is set, the correction control function used when dirt is detected is canceled.

Additional description and
notes SMTP authentication has the specifications of SMTP (Simple Mail Transfer Protocol), a protocol used
for mail transmission, plus a user authentication function. When mail is received, the user account and
password are authenticated between the SMTP server and user, and mail transmission is permitted
only when the account and password have been authenticated.
CRAM-M5 (Challenge Response Authentication Mechanism - Message Digest 5) is a user
authentication system which provides encryption so that the password character string will not pass
through the network in its original form.
