Troubleshooting 121.71 and 31.80E fuser error messages

Issue description

The [121.71] fuser error appears on the operator panel after the printer has been initially powered On.

A "Reinstall missing or unresponsive fuser [31.80E] recommended life exceeded [80.36]" message could also appear on the printer.

Both these issues can occur when printing a document and may cause some of the paper to get stuck in the printer.


To resolve this issue perform POR (power-on reset) or power the printer Off and power it back On after one minute.
