12 Troubleshooting Guide

12.1. Troubleshooting Summary

After confirming the problem by asking the user, troubleshoot according to the instructions and observe the following precautions.

12.1.1. Precautions

1. If there is a problem with the print quality or the paper feed, first check if the installation space and the print paper meets the

specifications, the paper selection lever/paper thickness lever is set correctly, and the paper is set correctly without any slack.

2. Before troubleshooting, first check that the connectors and cables are connected correctly (not loose).

If the problem occurs randomly, check it very carefully.

3. When connecting the AC power cord with the unit and checking the operation, exercise utmost care when handling electric

parts in order to avoid electric shocks and short-circuits.

4. After troubleshooting, double check that you have not forgotten any connectors, left any loose screws, etc.
5. Always test to verify that the unit is working normally.
