Question about HP Office Equipment & Supplies
HP Photosmart C4750 Print Scan Copy Owner Manual Can I download It? Or is it available online so I can read it and copy only the sections that i need.?
This URL contains both the User Guide and Reference guide for your printer. Once you select your language just download it.
Hope this helps

Check the following steps:
Connect the printer directly to the wall outlet and
1. Verify that the unit is switched on. Unplug the all-in-one from power and disconnect the connection port.
2. Wait 30 seconds.
3. Plug in the power only.
4. Repeat steps 2-4 two more times.
5. On the third time after plugging the unit into power, reconnect the connection port from the all-in-one to your computer.
1. Unplug the power cable from printer when the printer is powered on.
2. Press and hold # and 6 while plugging in the power cord
Try to check the result.

Did you just replace a cartridge? In any event, see this HP support article and follow the instructions. You may need to clean the cartridge and printer contacts for the cartridge to work correctly. Do this while the printer is turned off. Wait until the contacts are both thoroughly dry, then reinstall the cartridges with the printer on. (See here.)
If you have other questions about this model, your product home support page is here.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Set your wireless security to WPA with the cipher set to auto. If you have the cipher set to TKIP, the printer won't stay connected.
Even if you set the printer to use TKIP and the router to use TKIP, it won't hook up, and if it does, it won't stay connected. I have tried telling HP about this issue, but so far, just canned responses to my emails
