The document prints on the wrong side of the paper or upside
down? Check to make sure the paper is loaded correctly. See
“Loading media” on page 54 or “Printing on letterhead and
envelopes” on page 57.
Both sides of the duplex job printed on the same side? After
printing the first side, you probably placed the sheet into the top paper
input bin or the single-sheet input slot with the printed side facing you.
When duplexing, make sure to place printed side facing back.
Envelopes are not printing the correct way? Check that the
envelope is loaded correctly. See “Printing on letterhead and
envelopes” on page 57. Also, there may be a special adjustment
required by your program. See its documentation for instructions. You
may also want to try to print the envelope on a blank sheet of Letter or
A4 size paper so you can see where the words are printing.
A fax comes in while envelopes are loaded? Before you begin
printing envelopes, you can receive faxes to memory and then print
them after you have reloaded the normal paper. See “Receiving faxes
to memory” on page 136 and “Printing faxes received to memory” on
page 35.
If you couldn’t remove the envelopes before the fax began printing,
you can try to reprint the fax. See “Reprinting faxes” on page 36 for
instructions.
Cleaning up spilled toner
If toner spills on clothing, carpets, or upholstery, remove it using a
clean cloth dipped in cold water. Wash clothing in cold water. Hot
water and the heat of the dryer set toner into fabric.
