Transmission does 
not take place.
Does the job status screen (completed 
jobs) or a transaction report indicate that 
the transmission was not successful?
Perform the transmission again.
If the transmission is still not successful after recalling is 
performed as set in "Recall in Case of Line Busy" or 
"Recall in Case of Communication Error", the 
transmission failure will be indicated in the job status 
screen and the transaction report.

Did you place a long size original on the 
document  glass when it is scanned?
A long size original cannot be scanned from the 
document glass. Place originals in the document feeder 
tray of the automatic document feeder.
Did you place an original that is folded? If a folded original is placed in the automatic document 
feeder, an error will occur and scanning will be canceled 
when the actual original size is detected during 
scanning.
Following the instructions in the display, unfold the 
original, place it in the automatic document feeder 
again, and rescan.
Are the sub-address and passcode 
correct?
(When using F-code communication)
Check with the operator of the other machine to make 
sure that the sub-address and passcode are correct.
Have functions been disabled by the 
administrator?
When user authentication is enabled, the functions that 
you can use may be restricted in your user settings. 
Check with your administrator.
The transmitted fax 
prints out blank at the 
receiving side.
Is the original placed face up or face 
down correctly?
When using the document glass, the original must be 
placed face down. When using the automatic document 
feeder, the original must be placed face up. Place the 
original correctly and send the fax again.
If the receiving machine is using thermal 
paper, was the thermal paper loaded 
with the wrong side out?
Check with the operator of the other machine.
The transmitted fax is 
reduced by the 
receiving fax machine.
Has image rotation been enabled? When "Rotation Sending Setting" is not enabled (the 
image is not rotated), an original placed in the vertical 
orientation may be reduced by the receiving machine. 
Enable "Rotation Sending Settings" before 
transmission.
➞ System Settings (Administrator) > "Image Send 
Settings" > "Fax Settings" > "Fax Send Settings" > 
"Rotation Sending Setting" > 
If "Mixed Size Originals" in the special modes is enabled 
and an original with a different width is sent, rotate 
transmission will be disabled.
