carousel to bring the next print cartridge into the top position. The light for the print cartridge
that is approaching the top position blinks quickly two or three times.

This light indicates when the imaging drum is low (light is on), or empty or missing (light
blinks). The light also indicates when a non-HP imaging drum is installed (the light blinks and
the Attention light is on).

The printer has two buttons and three lights to indicate and control the printer status. To

You might not receive any indication when a non-HP supply is empty. If you continue

Generally, the Attention light blinks when the printer is out of paper, when a jam has
occurred, or when other problems that need attention occur.

The Attention light is on and one of the Supplies Status lights is blinking the first time a non-
HP supply is installed.

The Ready light is on when the printer is ready to print (experiencing no errors that prevent
printing) and blinks when it is receiving data to be printed.
