Introduction

HP LaserJet 1000 series printers use two light-emitting diodes (LEDs) to show the printer's status. This document describes these status lights and explains how to identify and interpret the patterns of light they produce.

Status lights

The status lights are located at the top left of the front of the printer. The Ready light indicates that the printer is ready to print or that the printer is processing data. The Attention light indicates that the input tray is empty, the toner door is open, the print cartridge is missing, or another type of error occurred.
