@If the metal strip is bent or broken, you’ll want to replace it. (Be
sure to get a 5MT 2-amp fuse, or its equivalent.)

n REPLACING THE PRINT HEAD The print head in your printer isvery durable and has an extremely
long design life. However, like most mechanical devices, it may
eventually wear out. If you ever do need to change the print head,
you’ll find that it, too, is easy to replace. Here’s how to do it:
@If the printer has been in operation, turn it off and allow about
10 minutes for the print head to cool.
.Lift the front cover and remove the ribbon cassette.
*Locate and remove the screws and washers that hold the print
head in place. (You may want to keep them in a cup so that they
don’t become misplaced.)
ORemove the print head from the carriage.
OHold the print head in one hand between the thumb and fore-
finger; with your free hand, gently disconnect the cable (attached
to the head) from the socket on the printer’s logic board (beneath
the rubber cover).
l Connect the ribbon cable from the new print head to the socket
on the logic board, and fasten the print head to the carriage with
the screws and washers.
