HPLIP

hp8500 wifi scanner not found (worked previously)

Asked by Lee Thompson

Up until last week, I was able to use xsane to scan documents from the hp8500 scanner, which is network-connected via wifi. I can still print, but today xsane refuses to find the scanner. I have gone through the troubleshooting on the hplip site with no success.

Operating system: ubuntu 11.10 oneiric, kernel 3.0.0-12-generic
Printer: HP Officejet Pro 8500A Plus

Here are my results from hp-check -t, followed by hp-setup and hp-makeuri

:~$ hp-check -t

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the
proper dependencies are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP
supplied tarball has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time
dependencies).

Hi Lee,

Pelase follow the below instructions.

1. Delete all the existing print queues.
2. Download and install our latest HPLIP 3.11.12 release from http://hplipopensource.com/hplip-web/gethplip.html. Installation instructions can also be found in the same page.
3. Re-configure the print queue using "hp-setup" from the terminal.

Let us know if the problem still perists.

Thanks for your response.

I followed steps one and two with no problem.

hp-setup ran into difficulty. i want to connect the printer via wifi, so I selected the third option (which requires temporary usb connection) on the hp-setup screen. I connected the printer via usb, and hp-setup appeared to find the printer, but when I clicked next, I got an error apparently related to the usb connection. Here is the terminal output:

Hi Lee,

Please follow the below instructions to configure the device through WiFi.

1. If you already know the IP Address of the device,
    a) Run "hp-setup <IP Address>" from the terminal and continue to confiugre the device.

2. If you dont know the IP Address of the device,
    a) Confiure the device to a router from the device front panel.
    b) Print the configuration page from the device front panel to know the IP Address.
    c) Now run "hp-setup <IP Address>" from the terminal to confiugre the device via WiFi

If the problem still persiste, post the output of "hp-check -t" here.

Thanks for using HPLIP.

you are awesome. Thank you very much for your help.

Just one more question, please:

Occasionally, after power outages or other router issues, the printer gets a different IP address. What is the easiest way to deal with this, when it happens? Recently seen IP addresses for the printer are: 192.168.4.114, 192.168.4.104, 192.168.4.116 192.168.4.101, currently 192.168.4.100.

I should perhaps point out that I am the administrator for the office network, so I have access to make changes to the router settings if needed. It's a Linksys WRT54G2, v2

Srikanth (srikanth-lokare) said : 		#5

Hi Lee,

If the router is configured for DHCP, the IP may change after every power outage or reboot. To solve this issue, you can request for the static IP from your internet service provider and configure your router to have this static IP.
