Problem

Error code D6/D7/D8/D9/DA/DB is displayed when the printer is working.

Cause

The printer has detected that the temperature of the fuser is abnormal.

Solution

1.         If the printer is going to be used in a scenario where the temperature or humidity changes greatly, place the printer in that environment for more than 4 hours before powering it on.

2.         Check whether the power supply of the printer is stable and whether the voltage is within the normal operating voltage range.

3.         Open the back cover of the printer and check whether there is a paper jam. If so, remove the paper.

4.         Go to the AI Life app on your phone or HUAWEI Print on your PC, go to Advanced, and click Reset Fuser.

5.         Restart the printer.

6.         If the issue persists, take your printer and proof of purchase to an authorized Huawei Customer Service Center for assistance. If your printer is newly purchased, you can contact your reseller or seller directly.
