1 Attention LED The Attention light blinks when the printer requires user attention, such as when the
printer runs out of paper or a toner cartridge needs to be changed. If the light is on without
blinking, the printer has experienced an error.
2 Ready LED The Ready light is on when the printer is ready to print. It blinks when the printer is receiving
print data or canceling a print job.
