"Turn Power Off then on Again" error

I've checked all of the cords and there is nothing obvious wrong with the printer, but it's giving me the "Turn Power Off then on Again" message... everytime I restart. I've unplugged and repluged a few times as well and the message keeps popping up. Anyone?

Try performing a reset on the device. Unplug the power cable, then hold # and 3 while powering it back up.

2. Open the cover of the product and remove the print cartridges.
3. Close the cover and wait for the Insert Ink Cartridges message to display.
4. Disconnect the power cord from the back of the product and wait for one minute.
5. Reconnect the power cord. If the product does not automatically turn on, press the Power button.
6. Open the cover and reinsert the print cartridges.
7. Close the cover. If prompted, print a calibration page.
8. Reconnect the USB or ethernet cable, and try to print a print job from the computer.

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 laserjet m1522f error 5 turn off and on


Hi, Error 5 is a Scanner error. When turning the printer on, have the lid up so you can watch the scanner movement. Does it move smoothly? It should go through a warm up and you should be able to watch the scanner movement. If there is a problem with the scanner, there isn't a lot you could do except. The service manual says the scanner assembly should be replaced. If it was my printer, I would try to take a closer look at the scanner assembly and check to see if the scanner unit is bound up somewhere, or maybe a drop of 3 in 1 oil on the scanner rails. Let us know what happens.
thanks
