# GENERAL PROBLEMS

## Overview

Problem | Point to check | Solution
--- | --- | ---
###### SPECIFIED MACHINE FUNCTIONS CANNOT BE USED | Have functions been disabled by the administrator? | Check with your administrator. Some functions may have been disabled in the setting mode. When user authentication is enabled, the functions that you can use may be restricted in your user settings.
###### THE OPERATION PANEL CANNOT BE USED | Is the main power indicator lit? | If the main power indicator is not lit up, turn the machine's power on. Make sure that the power plug is firmly inserted in the power outlet, switch the main power switch to the "" position, and press the [POWER] button to turn on the power.
Did you just power on the machine? | Wait until a message appears indicating that the machine is ready. After the [POWER] button is turned on, the machine requires some time to complete warmup operation. During warmup operation, functions can be selected, but a job cannot be run.
Is the [Power Save Mode] button blinking? | Auto Power Shut-Off mode has activated. To return the machine to normal operation, press the [Power Save Mode] button. AUTO POWER SHUT-OFF TIMER
Is a cover open or a device separated from the machine? | Read the message and take appropriate actions. A warning message will appear when a cover is open or a device is separated from the machine.
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.) => "Setting mode (administrator)" → [User Control] → [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 Login] 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 message "Call for service. Code: xx-xx*" appears on the touch panel? *Letters and numbers appear in xx-xx. | Turn on the machine power again. Make sure that the background colour of the job management display at the upper right corner of the touch panel is grey, and press the [POWER] button and then turn the main power switch to the "" position. Wait at least 10 seconds and then turn the main power switch to the "" position. After the main power indicator changes from flashing green to the lit up state, press the [POWER] button. 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 servicing. 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.)
