Make sure that the power plug is firmly inserted in the power outlet, switch the 
main power switch to the "
" position.
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. For more information, see the 
"User's Manual" .
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.)

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

turn the main power switch to the "

■ 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.)

General Problems
For copy mode, you can set copying 
to black & white priority. For printing 
mode, you can set printing to black & 
white priority in the printer driver 
settings. 
■ Although this does not prohibit color copies, you can set the color mode to black 
& white priority as a means of reducing the number of color pages printed.
 
Copying
⇒ Set "Setting mode(administrator)" → [System Settings] → [Copy Settings] → 
[Initial Status Settings] → [Color Mode] to [B/W]
Printing

THE ORIGINAL SIZE IS NOT AUTOMATICALLY 
SELECTED OR THE WRONG SIZE IS SELECTED
Check
Solution
Is the original curled or folded?

■ Select the original size manually. 
Original sizes smaller than A5 (5-1/2" x 8-1/2") cannot be detected. When 
scanning a small original on the document glass, it is convenient to place a blank 
sheet of paper on top of the original which is the same size (A4 (8-1/2" x 11"), B5 
(8-1/2" x 11"R), etc.) as the paper that you wish to use for printing.

size to [Long Size].
 
(Note that long originals cannot be copied using the copy function.)
Is the original on thin paper?
■ Use the document glass to scan the original.

the machine?
■ Follow the instructions in the touch panel to remove all paper.

exceed the indicator line.
► Placing the original and adding paper (page 5)
Are multiple sheets feeding at once?
■ Fan the paper well before loading it.
Are you using paper that is not within 
the specifications?
■ Use SHARP-recommended paper. 
Using paper that is for other models or special paper that is not supported may 
result in misfeeds, creases, or smudges.
⇒ - "SUPPLIES" in Start Guide
For paper that is prohibited or not recommended, see User's Manual.
Are the bypass tray guides adjusted 
to the width of the paper?

contact the sides of the paper.

pulled out?
■ When loading large-size paper, pull out the extension guide.
► Placing the original and adding paper (page 5)
Is the bypass feed roller dirty?
■ Clean the surface of the bypass feed roller.
► Maintenance (page 6)
Is A5 (5-1/2" x 8-1/2") size paper 
loaded?
■ When loading A5 (5-1/2" x 8-1/2") size paper, place the paper in the horizontal 
(A5R (5-1/2" x 8-1/2"R)) orientation. (Excluding cassette 1 and the bypass tray)
Is the paper size specified?
■ If you are using a non-standard size, be sure to specify the paper size. 
 If the size of paper loaded into a tray was changed, be sure to check the paper 
size setting.
⇒ "Setting mode" → [System Settings] → [Common Settings] → [Paper Settings] 
→ [Paper Tray Settings] → [Tray Registration]
Did you add paper to the bypass tray?
■ When adding paper, remove any paper remaining in the bypass tray, combine it 
with the paper to be added, and reload as a single stack.
 
If paper is added without removing the remaining paper, a misfeed may result.
Are you using punched paper?
■ When using punched paper, set the paper type to punched.
