Nothing lights on the operation panel

power cord securely, and try turning on 
the printer’s power again.

The printer prints a status page, but 
does not print jobs from the computer.Check the printer cable or the interface 
cable.Connect both ends of the printer cable 
securely. Try replacing the printer cable 
or the interface cable.
Check program files and application 
software.Try printing another file or using 
another print command. If the problem 
occurs only with a specific file or 
application, check the printer driver 
settings for that application.
The printer is emitting steam in the 
area around the top tray.Check the room temperature to see if it 
is low, or if damp paper was used.Depending on the printing environment 
and the papers condition, the heat 
generated during printing will cause the 
moisture in the paper to evaporate, and 
the steam emitted may look like 
smoke. This is not a problem, and you 
can continue printing.
If the steam concerns you, raise the 
room temperature, or replace the 
paper with a newer, dryer paper.
