HP Officejet Pro 8500A - Manual (Page 139)

ƕ Inspect the ends of the memory device for dirt or material that closes a hole or
spoils a metal contact. Clean the contacts with a lint-free cloth and small
amounts of isopropyl alcohol.
ƕ Make sure that the memory device is working correctly by testing it with other
devices.
• Check the memory device slot
ƕ Make sure that the memory device is fully inserted into the correct slot. For
more information, see Insert a memory device.
ƕ Remove the memory card (when the light is not blinking) and shine a flashlight
into the empty slot. See if any of the small pins inside are bent. When the
computer is off, you can straighten slightly bent pins by using the tip of a thin,
retracted ballpoint pen. If a pin has bent in such a way that it touches another
pin, replace the memory card reader or have the printer serviced. For more
information, see HP support.
ƕ Make sure that only one memory device has been inserted at a time in the
slots. An error message should appear on the control-panel display if more
than one memory device is inserted.
The printer cannot read photos on the memory device

Solve wired (Ethernet) network problems
If you are unable to connect the printer to your wired (Ethernet) network, perform one
or more of the following tasks.
NOTE: After correcting any of the following, run the installation program again.
• General network troubleshooting
• Network port created does not match printer IP address (Windows)
General network troubleshooting
If you are unable to install the HP software provided with the printer, verify that:
• All cable connections to the computer and the printer are secure.
• The network is operational and the network hub is turned on.
• All applications, including virus protection programs, spyware protection programs,
and firewalls, are closed or disabled for computers running Windows
• The printer is installed on the same subnet as the computers that use the printer.
If the installation program cannot discover the printer, print the network configuration
page, and enter the IP address manually in the installation program. For more
information, see Understand the network configuration page.
Though it is not recommended that you assign the printer with a static IP address, you
might resolve some installation problems (such as a conflict with a personal firewall)
by doing so.
