Question about HP DeskJet 3820 InkJet Printer

1 Answer

Blank page I have this printer attached to an ophthalmis machine which has no screens to be able to ask it to do things. I only have the buttons on the front to work with. I have not used the printer for 10 days and the service chappy who has mended my machine it is attached to thinks I need to clean the print head. How do I do this? Or do I need to try something else?

You can run a self-test independent of the device your printer is attached to:
1. Turn the printer ON.
2. Press and hold the POWER button.
3. Press the RESUME button FOUR times.
4. Release the POWER button.

If that works, I would suggest taking a laptop or small PC to the printer and hooking it up. Try printing from the laptop. Let me know the results and we'll go from there.

My Dell 3115cn printer will not connect to the network (it still works on USB cable), hard to believe it's broken, so can the printer system be reset?


Try turning off the printer and disconnecting power plug from wall. Hold power on button for about a minute. Then replug unit and turn power on - it should then attempt to hook up to your existing network.

If no go, try reinstalling the software that initially came with printer and was used to set up the network

Do you have a CD to install this printer? if you do go into MY COMPUTER where you can erase things and erase the printer and its system then shut computer off and restart then reinstall the printer using your CD to reinstall it. Some times you have to delete things and reinstall them to work.

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

HP printer psc 2210 all in one


Chances are that you didn't lock down the scanner when you moved the unit. You can attempt to open the unit and move the scanner bar manually to reset it. HPs are very difficult beasts when it comes to their power up check out. It must be fully functional...including all cartridges...to work in most cases. Good luck.
