Star Micronics XB24-10, XB24-15 user manual Replacing The Print Head

REPLACING THE PRINT HEAD

This is not ajob which you will need to do very often. The print head has been designed to give a life of about 200 million dots. In normal everyday use, this will mean years of life. However, if the print quality is faint, even after you have changed the ribbon, the print head will need replacement.

Only use a replacement print head as recommended by your supplier.

NOTE

This is a fairly tricky operation. Read the instructions below carefully before attemptingit. If you are in any doubt as to your competence to perform it, call in the experts before you start.

1 Turn OFF the printer, and remove the power cable.

2If the printer has been in operation immediately before this operation, the print head will be hot.

NOTE

Allow time for the print head to cool before attempting to work on it,
