CentreWare Internet Services Problems
Symptom Cause/Remedy
Entered text in a text box within 
the number of bytes allowed for 
the text box (when one non-
alphanumeric character is 
counted as 2 bytes), but the 
whole text was not saved.
This printer uses Unicode UTF-8 to save characters entered on CentreWare Internet 
Services. In general UTF-8 requires 2 to 4 bytes to save one non-alphanumeric 
character. 
The text you entered may have exceeded the maximum number of bytes allowed for 
the text box, and thus was not saved.
Cannot access to CentreWare 
Internet Services.
Is the printer running normally?
Check if the printer is switched on.
Is Internet Services activated?
Print out the [Printer Settings] list to see if Internet Services is activated.
Is the URL entered correctly?
Check the URL. If you still cannot access the service, enter the printer's IP address 
instead of the URL.
Is the number of HTTP port correct?
Check the HTTP port number again. If you changed the port number, you must enter 
a  ":" (colon) and then the port number after the address when accessing 
CentreWare Internet Services.
Example) http://printer1.example.com:80/
If SSL/TLS server communication is enabled, did you enter the address correctly in 
the address field? 
If SSL/TLS server communication is enabled, start the address with "https" instead of 
"http". Also, if you changed the SSL/TLS port number, enter a ":" (colon) before the 
port number. 
Is your web browser using a proxy server?
CentreWare Internet Services cannot be accessed depending on the proxy server 
being used.
Try accessing the service without using a proxy server.
