Before You Begin
Safety
To prevent fire hazard, never use flammable aerosol sprays around the machine.
Before you replace any unit, to prevent electrical shock, turn off the machine with the operation
power switch at the left, front corner of the machine. Wait for the machine to shut down, and
then disconnect the machine from the power supply.
Allow the machine to cool for at least 30 minutes before replacing a part.
Do not remove any covers or screws other than those explicitly mentioned in a procedure.
Inside this machine are high voltage components that are an electric shock hazard and laser
components that could cause blindness.
About the Display for Options
This machine displays all of the adjustment items in the “Adjustment Settings for Skilled Operators”
menu and advanced settings for custom paper regardless of whether or not the items are for options, or
if the options have been installed.
Any modification to the option settings does not take effect unless the applicable options are
installed on this machine.
Settings can be adjusted with the “Advanced Settings for Skilled Operators” (the product specialist
who have received TCRU training), or with SP codes settings by the CE.
In this guide, the skilled operator adjustment is given first, followed by the corresponding SP code
setting which can be done by the CE only.
Always note the current setting before you make any change.
If a problem persists despite the setting being changed, restore the value you made a note of.
Operating the machine with the changed setting may cause problems such as reduced print
quality.
If the problem persists even though the setting has been changed, restore the value noted.
Operating the machine with the changed setting may cause problems, such as inferior printed
images.
