cannot be used.
Does the message "Call for service. 
Code:xx-xx*." appear in the touch 
panel?
*Letters and numbers appear in xx-xx.
Make sure that the LINE indicator is not lit and that the 
DATA indicator is not blinking or lit and then switch off 
the [POWER] key (
) and the main power switch.
Wait at least 10 seconds and then switch the main 
power switch and the [POWER] key (
) back on in
that order.
If the message still appears after switching the

) and 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.)

document filing)?
Check the Paper Tray Settings and see if checkmarks 
appear in the checkboxes of each mode (Feeding
