Cause
There is a possibility that the
PDF version is not supported
by the browser's PDF viewer
or an unsupported
encryption level is specified.
The scanning glass or guide
plate of the ADF is dirty.
The output tray is full.
Large print runs will cause
the machine's interior to heat
up, triggering the cooling
fan.
The machine is performing
image adjustment
operations.
When Other Messages Appear
Solution
With this machine's browser PDF files
other than those whose versions and
encryption levels are specified below
cannot be viewed.
• PDF version: 1.3-1.7
• PDF encryption level: 128Bit AES
or 256Bit AES
Clean the scanning glass or guide
plate. See "Maintaining Your
Machine", Maintenance and
Specifications.
Remove paper from the output tray to
resume printing. Press [Continue] on
the display panel to resume printing.
The fan will emit noise, but this is
normal and the machine will be
operable while the fan is running.
The amount of paper that can be
printed and the total operation time
until the fan starts running depends on
the temperature of the location at
which the machine is installed.
The machine may perform periodic
maintenance during operations. The
frequency and duration of
maintenance depends on the humidity,
temperature, and printing factors such
as number of prints, paper size, and
paper type. Wait for the machine to
resume operation.
