Problem-solving checklist

If you are experiencing problems, use the following checklist to identify the cause of the problem:

●Is the device connected to power?

●Is the device on?

●Is the device in the Ready state?

●Are all necessary cables connected?

●Do any messages appear on the control panel?

●Are genuine HP supplies installed?

●Was a recently replaced print cartridge installed correctly, and was the pull tab and/or attached tape on the cartridge removed?

For additional information about installation and setup, see the getting started guide.

Factors that affect performance

Several factors affect the time it takes to print a job:

●The use of special paper (such as transparencies, heavy paper, and custom-size paper)

●Device processing and download time

●The complexity and size of graphics

●The speed of the computer you are using

●The USB connection

●The I/O configuration

●The amount of memory installed

●The network operating system and configuration (if applicable)

●Device personality (PCL or PS)

NOTE Although additional memory can resolve memory problems, improve how the device handles complex graphics, and improve download times, it will not increase maximum printing speed (ppm).
