You can select “64 bit” or “128 bit” length and
“Hexadecimal” or “ASCII” format for the encryption key.
Longer key length can provide stronger security but worth
communication performance.
Enter four key values by following the rules below and
select one key as the default key.
 PassPhrase – A passphrase simplifies the WEP encryption
process by automatically generating the WEP encryption keys
for the print server. This setting is only valid when the security
mode is in “WEP(HEX)”.

Key 1 to Key 4 – If the key length is 64-bit, enter 10-digit Hex
values or 5-digit ASCII values as the encryption keys. For
example: “0123456aef“ or “Guest“.
If the key length is 128-bit, enter 26-digit Hex values or 13-
digit ASCII values as the encryption keys. For example:
“01234567890123456789abcdef“ or “administrator“.
