hello
Thanks for posting on the HP Forums!
I should be able to provide some suggestions that may help. Are you getting an error on the printer or does it just go blank and flash? The first thing I suggest is to plug the printer into the wall outlet directly if it is currently in a power surge protector or extension cord. This may sound silly but this will ensure the printer is getting full power and may eliminate any unnecessary troubleshooting. If the printer is no longer getting full power from the power surge or extension cord it may give false errors, have poor connection,paper feed issues and quality issues.
Here are some settings you can have changed in the router for networking a printer. You should be able to contact your router company and ask them to make sure:
~ Network name and password need to have NO SPACES OR PUNCTUATION
~ Must be using WPA security
~ Encryption Type 128-bit
~ Dual broadcast Wireless b/g/n (printer will only connect to g)
~ MAC filter needs to be turned off
~ Multicasting Must be turned on
~ Bonjour must be enabled
~ Dual band set to 2.4 Ghz
~ Correct Wireless Channel (not 1,, 6,, 11)
~ Router Firmware Updates
~ Firewall settings need to be at there default settings, or set to a lower security
~ Following ports need to be un-blocked:
Incoming (UDP) ports : 137, 138, 161, 427 (iPad 80, 443)
Outgoing (TCP) ports : 137, 139, 427, 9100, 9220, 9500 (iPad 5222, 5223)
Please post back and let me know how it goes!
