For the characters that can be used for login user names and passwords, see the section below:
Usable Characters for User Names and Passwords
You cannot specify the same login user name for the supervisor and the administrators.
Using Web Image Monitor, you can log in as the supervisor and delete an administrator's
password or specify a new one.
The following characters can be used for login user names and passwords. Names and passwords are
case-sensitive.
Upper case letters: A to Z (26 characters)
Lower case letters: a to z (26 characters)
Numbers: 0 to 9 (10 characters)
Symbols: (space) ! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _` { | } ~ (33 characters)
Login user name
Cannot contain spaces, colons or quotation marks.
Cannot be left blank.
Can be up to 32 characters long.
The login user name of an administrator must contain characters other than numerical
characters (numbers) if it is up to 8 characters. If it consists of only numbers, 9 or more
must be used.
Login password
The maximum password length for administrators and supervisors is 32 characters and
128 characters for users.
There are no restrictions on the types of characters that can be used for a password. For
security, it is recommended to create passwords consisting of uppercase or lowercase
characters, numbers, and symbols. A password consisting of a large number of characters
is less easily guessed by others.
In [Password Policy] in [Extended Security Settings], you can specify a password
consisting of uppercase or lowercase characters, numbers, and symbols, as well as the
minimum number of characters to be used for the password.
