❏
Always close the printer’s covers gently. Never subject the printer to vibration.
❏
Do not cover the printer immediately after using it. Turn it off and wait until it cools down.
❏
Do not leave the printer’s covers open for any length of time, especially in well-lit places; light may
damage the photoconductor units.
❏
Do not open the printer during printing.
❏
Do not tap media stacks on the printer.
❏
Do not lubricate or disassemble the printer.
❏
Do not tilt the printer.
❏
Do not touch the electrical contacts, gears, or laser devices. Doing so may damage the printer and
cause the print quality to deteriorate.
❏
Keep media in the output tray at a minimum level. If the media is stocked too high, your printer
may experience media misfeeds and excessive media curl.
❏
Make sure two people are available to lift the printer when moving it.
Keep the printer level to avoid toner spillage.
❏
When lifting the printer, fold up Tray 1, and then lift the printer as shown in the illustration at the
right.
If the optional 500-sheet paper cassette unit is installed, move it and the printer separately. Do not
grasp the grip of Tray 3, or the right side cover; otherwise, the 500-sheet paper cassette unit may be
damaged.

If you get toner on your skin, wash it off with cool water and a mild soap.
