Symptom Check Items C
orrective Actions
Print quality is poor. – Refer to  Print Quality Problems on page6-3.
Text is missing on the 
Windows test page. – This is a problem specific to the Windows OS. It is 
not a printer problem. It does not affect print quality. 
Paper is jammed. – Refer to  Clearing Paper Jams on page6-12.
Nothing lights on the 
operation panel even 
when power is turned on 
and the fan makes no 
noise. Check the power cord is property 
plugged into power outlet.
Connect both ends of the power cord securely. Try 
replacing the power cord. Refer to 
Installation Guide 
for more information.
Check the power switch is in the 
On ( | ) position. Refer to the 
Installation Guide  for more information.
The printer prints a status 
page but data from the 
computer is not being 
printed. Check program files and application 
software.
Try printing another file or using another print 
command. If the problem occurs with a specific file or 
application, check the printer settings for that 
application.
Check the interface cable. Connect both ends of the interface cable securely.  Try replacing the printer cable. Refer to the 
Installation Guide for more information.
Vapor is emitted at the 
rear of the printer. Check if the temperature is low near 
the location of the printer, or if the 
paper that is being used has been 
exposed to humidity. Depending on the operating environment of the 
printer and the condition of the paper, heat 
generated during printing can evaporate water 
moisture in the printed paper, emitting vapor from the 
printer. In this case, printing can be continued 
without any problem.
To correct this, increase the temperature in the room, 
and use paper that has been stored in a dry place.
