5. LT-286 maintenance
This chapter explains the procedure for maintanance work and is intended for maintanence personnel in the field.
5.1. Handling and maintanence of printer
1) The use of paper other than our recommended paper may cause poorer quality of and duration. Be sure to use
paper with a width within the specified range.
2) Do not give the surface of the head circuit board (heating elements) a mechanical shock.
3) In handling the printer, take anti-static measures and ground the human body to protect the heating elements, ICs,
and other parts from damage due to static electricity.
4) Wipe off lightly any dirt stuck on the surface of the heating elements with a cotton swab soaked in ethanol or the
like.
5) Activating a wet thermal head is likely to damage the head. If moisture is present on the head, dry it thoroughly
before printing.
6) Feed paper in the head-up condition. Cut the forward end of paper straight. Do not insert paper with its forward
end fluffed or bent. When the forward end of paper comes out of thermal head, confirm that the paper has been
set straight before putting the head down.
7) Take paper out in the head-up condition. Take paper out slowly and straight in the direction in which paper comes out.
