This is a zero crossing error often caused by power surges. The only clear that I know of is to do a fuser reset, simulation 163.

This is not a laser/polygon motot error. It is caused usually by power fluctuations the power supply and or engine boards cause it. Fuser clear will correct it.

Zero-crossing signal problem

The engine board (KP-5061) does notdetect the zero-crossing signal for thetime specified below.At power-on: 3 s

Others: 5 s

This machine has slightly different method to get to the simulation mode. See this article:

This will not work for KM1500. It doesn't has system menu/counter key.
