Status and Error Messages
This section contains a list of error messages shown on the LCD 
panel, giving a brief description of each message and suggestions 
for correcting the problem. Note that not every message shown 
on the LCD panel indicates a problem. 
Calibrating Printer
The printer automatically calibrates itself when any of its covers 
are opened and there is no error inside. This is not an error 
message, and will clear itself after a few minutes. While the 
printer displays this message, do not open the covers or turn off 
the printer.
Cancel All Print Job
The printer is canceling all print jobs in the printer memory, 
including jobs the printer is currently receiving or printing. This 
message appears when the   Cancel Job button has been pressed 
down for more than 2 seconds.
There may be no paper in the 
cassette or MP tray.
Load paper.
Too many sheets may be 
loaded in a cassette or MP tray.
Make sure that you have not tried to 
load too many sheets of paper. For the 
maximum paper capacity for each 
paper source, see “MP tray” on page 33.
If paper does not feed from the 
optional 500-Sheet Paper 
Cassette Unit, the unit may not 
be installed properly.
For instructions on installing the unit, 
see “500-Sheet Paper Cassette Unit” on 
page 169.
