General Problems
Did login fail three times in a row? ■ After operation unlocks, log in using the correct user information. 
When [A Warning when Login Fails] is enabled in the setting mode and login fails 
3 times in a row, a warning will be displayed and user authentication operation 
will lock for 5 minutes. 
(If you do not know your user information, contact your administrator.)
 "Settings (administrator)" → [System Settings] → [Authentication Settings] → 
[Default Settings] → [A Warning when Login Fails]
Does a message appear indicating 
that Auto Login failed?
■ Check with your administrator. 
Auto Login failed due to network or other problems.  If you are the administrator, 
tap the [Administrator Password] key, log in as an administrator, and temporarily 
change the auto login settings in the setting mode. (Restore the changed settings 
to their original state after the problems have been solved.)
Does the message "Call for service. 
Code:xx-xx*." appear in the touch 
panel?
*Letters and numbers appear in xx-xx.
■ Turn on the machine power again.
■ Make sure that the background color of the job status display at the upper right 
corner of the touch panel is gray, and press the [Power] button and then turn the 
main power switch to the " " position. Waiting at least 10 seconds and then 
turn the main power switch to the " " position.
■ If the message still appears after switching the [Power] button and the main 
power switch off and on several times, it is likely that a failure has occurred that 
requires service. In this event, stop using the machine, unplug the power plug, 
and contact your dealer or nearest SHARP Service Department.  (When 
contacting your dealer or nearest SHARP Service Department, inform them of 
the displayed error code.)
