General information
In order to maintain your machine in good working order,
it is recommended to periodically clean the inside.
Normal use of the machine, requires the following rules to
be respected:
•
When cleaning the inside of the printer or removing
jams, be careful not to touch the fuser unit or other hot
parts.
•
To clean the printer, use a soft cloth.
•
Never spray detergent directly onto the printer as it
may infiltrate the vents and damage internal circuits.
•
To clean the machine, avoid using abrasive or corro-
sive solvents or products containing solvents (alcohol
or benzene).
•
Always start by applying the cleaning product (mild de-
tergent) to a small surface of the printer to check the
result.
•
Never use abrasive or rough cloths (steel wool or plas-
tic).

Never leave the scanner cover open unnecessarily.

Never try to lubricate the machine.

Close the scanner cover gently and never subject the
machine to vibrations.

paper tray.
