Sharp AR-157E ユーザーズマニュアル

If nothing prints even when the unit is turned on, please wait a few moments. The unit needs a longer time to process  
intricate data. If the unit still does not print, refer to the check list below.

When the misfeed (

) indicator blinks or (

) 

blinks in the display, the unit will stop because of a 
misfeed.
Remove the jammed paper as explained in 
"MISFEED REMOVAL" in the Operation Manual.

The ONLINE indicator on the operation panel turns 
off while the unit is used for copying. Printing is not 
possible at this time. When copying is finished, the 
ONLINE indicator will turn on after the set auto 
clear time elapses, and the unit will be ready for 
printing. You can also press the clear (

) key 

twice or press the ONLINE key to make the unit 
ready for printing.

When choosing "Print" from the "File" menu located in 
applications, be sure you have selected "SHARP AR-
XXXX" (where XXXX is the model name of your unit) 
printer displayed in the "Print" dialog box.

Check if the printer driver has been installed, 
following the steps listed below.

Click the "start" button, click "Control Panel", 
click "Printers and Other Hardware", and then 
click "Printers and Faxes".
On Windows 95/98/Me/NT 4.0/2000, click the 
"Start" button, select "Settings" and then click 
"Printers".

If you still cannot print after confirming the "SHARP AR-
XXXX" (where XXXX is the model name of your unit) 
printer driver icon, the printer driver may not have been 
installed correctly. In this case, delete SHARP Personal 
MFP series software and then reinstall it.
