Introduction

1. 1 About This Manual

This service manual gives all the information necessary for you to adjust and repair the

This service manual is written only for SATO authorized service personnel.

The information in this manual is conﬁdential to general users.

For basic speciﬁcation, installation, operation and conﬁgurations of the printer, refer to

the operator manual of the PW4NX.

Since all problems that may arise during adjustment and repair work cannot be

described in this document, service personnel should always pay attention to safety in

addition to the precautions described in this document.

1. 2 Precautions

• Always power oﬀthe printer and disconnect the AC power cord from the outlet before

you start any maintenance procedures including parts replacement.

• Wear a properly grounded static wrist strap as required during repair work.

• Wear proper gloves during adjustment and repair work.

• Do not touch the printing element with your bare hand when you replace the print

head (thermal head).

• Hold the circuit board on the sides. Do not touch the components or bend the circuit

board when you remove or install the circuit board.

• Do not touch the cutter with your hands, nor place objects into the cutter. Doing so
