Remedy Move the printer to a location that is not exposed to direct sunlight or strong
light. Alternatively, separate the printer from the source of the strong light.
One portion of a page does not print.
Cause 1 The scale factor is incorrect.
Remedy 1 Clear the checkmark from [Manual Scaling] in the printer driver. When this
checkbox is cleared, the scaling factor is automatically determined based on the
[Page Size] and [Output Size] settings.
In order to update the [Manual Scaling] setting, open the [Page Setup] sheet.
Remedy 2 Place a checkmark next to [Manual Scaling] in the printer driver and specify an
appropriate scale factor according to the paper size you are using.
In order to update the [Manual Scaling] setting, open the [Page Setup] sheet.
Cause 2 The paper is loaded in the wrong position.
Remedy Load the paper properly. (See "Printing on Plain Paper, Heavy Paper, Label
Paper, and Transparencies," on p. 2-13, "Printing on Index Card," on p. 2-26,
"Printing on Envelopes," on p. 2-33, "Printing on Custom Paper Sizes
(Non-Standard Sizes)," on p. 2-44)

printable area of the printer.
Remedy The printable area of the printer is bounded by margins of 4 mm at the top,
6 mm at the bottom, and 5 mm on the left and right (for index card and
envelopes, the top, bottom, left and right margins are all 10 mm). Make sure you
have made sufficiently large margins in your data.
The front or back of printouts is stained with black dots.
