Basic troubleshooting checklist
If you are experiencing problems with the printer, this checklist may help identify the cause
of the problem.
● Is the printer connected to power?
● Is the printer on?
● Is the printer in the Ready state?
● Are all necessary cables connected?
● Are any messages displayed on the control panel?
● Was a genuine HP supply installed?
● Were recently replaced print cartridges installed correctly? Was the pull tab on the
cartridge removed?
● Were recently installed supply items (image fuser kit, image transfer kit) installed
correctly?

Factors affecting printer performance
Several factors affect the time it takes to print a job. Among these is maximum printer speed,
measured in pages per minute (ppm). Other factors that affect printing speed include the use
of special paper (such as transparencies, heavy paper, and custom-size paper), printer
processing time, and download time. Other factors include:
● the complexity and size of graphics
● the printer I/O configuration (network versus parallel)
● the speed of the computer you are using
● the amount of printer memory installed
● the network operating system and configuration (if applicable)
● printer personality (PCL or PostScript 3 emulation)
Note Adding additional printer memory might resolve memory problems, improve how the printer
handles complex graphics, and improve download times, but it will not increase maximum
printer speed (ppm rating).
