Can you tell me why my wireless HP PhotoSmart 7510 printer keeps dropping out? Thanks!
Do you connect the printer to an existing wireless network or are you using the HP wireless direct feature/connection?
If you are using the direct connection my first guess would be power settings as previously mentioned.
If you are using an existing network make sure all the security configurations are supported by the printer (security protocol and encryption).
Also it's a good idea to enable SSID broadcast or in other words not hiding your networks SSID as this may also cause dropouts of the printer.
Other issues can be caused by wide-channel or dual-antenna configurations.
For example if you have a single network (SSID) transmitted via two antennas e.g. one running 802.11N at 2.4GHz and the other 802.11G at 2.4GHz. Your printer may regularly switch between them either out of confusion or erratic signal strength.
The recommended setup would be a single network, on a single-band (2.4GHz) via a single antenna.
The energy mode seems to be the problem, set the energy save mode to 15 minutes then unplug the printer, wait 1min and plug it back, see if it will help.
From the front of the printer: Setup-Preferences-Auto-Off -Off.
The Printer Turns Off Unexpectedly after Being Idle for a Period of Time
1. Turn off the sleep mode.
2. Turn off the auto shut off.
3. Manually assigne an IP address
How can you tell the energy mode is the problem?
Printer Does Not Maintain Wireless Connection
well energy saving it is a suggestion and if the procedure fix the problem then it comes from energy saving mode perhas linked to a bug in the firmware?
HP Photosmart 7510 Energy Saving Mode Problem
Are you using the most current drivers for the printer? There have been updates posted that deal specifically with this issue for the entire PhotoSmart line.
Is your router protected?
How far away from the router is the printer?
How old is the router?
I hate to be "that guy", but probably just because it's an HP printer. These things are designed to be disposable.
I've never been able to find any pattern with my HP printer, and have had the same problem while attempting to help other people. The best you can do is restart the thing and hope the problem doesn't come up again next time – but it will. It always will.
