Using the Setup Analyser
When you print a document, you may want to have the printer driver
check whether you chose the correct paper source for the paper size you
are using. For example, if you specified envelope or a custom size for your
paper size, the system can check to make sure you are using the
appropriate paper source (manual feed). If the Setup Analyser detects a
mismatch, you choose the most appropriate action to take to handle the
situation.
If you turn on the Setup Analyser, the paper source and paper size are
checked for a match. If you turn off the Setup Analyser, no checking occurs.
To turn the Setup Analyser on and off:
On the Setting tab, click the buttons beneath the Setup Analyser icon to
turn it on and off.
To handle mismatches found by the Setup Analyser:
If the Setup Analyser detects a mismatch, select the mismatch. Then
select one of the following actions in the Print Setup Analyser dialog
box.
