警 告
WARNING
• Indicates a situation which, if not observed and handled properly, could result in death
or serious injury.
CAUTION
• Indicates a situation which, if not observed and handled properly, could result in injury.
CAUTION
(1) If a paper type other than the recommended paper is used, printing quality or service
life may not be guaranteed. Also, be sure to use the paper of the specified width.
(2) Use a ribbon cassette for the CD-S500 series. If any other ribbon cassette is used,
some problem, such as print head wire malfunction or poor printing quality, may
occur. Do not supply ink to the ink ribbon.
(3) Do not attempt to print without printing paper and a ribbon cassette mounted. Doing
so would damage the print head and the platen surface resulting in poor printing
quality and shortened service life.
(4) When moving the head, be sure to do so by rotating the gear. Moving the head
directly by hand would apply an overload to the carriage pin causing a time lag in
printing, etc.
(5) Avoid installing the printer in a place where dust, dirt or metallic particles are present.
(6) Be careful not to attach any foreign matter to the circuit boards.
CAUTION
(1) Avoid storing the printer in a place where dust or dirt is present or a place of high
temperature or humidity.
(2) When storing or transporting the printer, be sure to remove the ribbon cassette.
Failure to do so may cause a problem such as poor printing quality.
