Hey there, tmiller. Sorry you're having printer troubles. Happens to all of us. :-) The most likely cause is that cartridges are supposed to have a chip on the front (green and gold in the picture below) so that the printer can recognize them. Some aftermarket cartridges do not have those chips. If your cartridges do NOT have the chip, your printer won't recognize that you have ink. It should still print fine if you can clear the error message though. Try pushing the "OK" or back button and see if that helps. If there is a chip on the cartridges, I recommend you start by checking if the chip is defective or incompatible with your printer (happens sometimes, especially if ink cartridge is not made by the same brand as your printer). Use your fingernail or a razor blade (carefully!) to pick it off and then try clearing the error like above. Let us know if you get it to work. -- Spencer JR

Lot's of different things could cause this. Is the screen cracked? Did you drop it recently? Have you tried restarting the phone? Let us know if that works. -- Spencer JR iOSAnomalies.com

Hmm... something probably disconnected internally when you dropped it. If it doesn't get better. I recommend taking it apart and looking at the charger port or taking it into a dealer for them to look at. Let us know if you get it fixed somehow. -- Spencer JR

Hey there, PCHookups. Both of those problems could be caused by something not being properly attached if the digitizer cable and the connector for some of the memory weren't properly seated so I recommend opening it back up and double checking all the screws and cable connections. Best of luck and let us know if that helps! -- Spencer JR

I had this happen once but there was part sticking out of the jack. Any chance you could reach it with needle nose pliers?

Maybe something wasn't properly seated when you did the repair and got shaken out of place. Have you gotten a chance to look inside the iPhone after it stopped working? Do phone calls work now that the charger stopped?

Very odd. I just had this same thing happen on my iPhone 5. What carrier do you use? I use a Verizon reseller and a month or so ago, it started giving me pop-ups every couple hours that said "No SIM" or "Invalid SIM" and wouldn't let me access texting, calling, or data (Wifi still worked) and would stay like that until I restarted. I contacted the Verizon reseller and they said I needed to buy a new SIM (just got this one in the last 6 months). I didn't want to pay for that so I just waited and it hasn't done it again in at least a month. How long has this been going on? Have you checked if the chassis pushes on the SIM or board? I don't know much about Samsungs so pardon my question, can your phone tell if the cover is on or not? If not then it has to be a physical problem since taking the cover off helps. You could also try contacting Samsung, your carrier, or wherever you bought your SIM; probably won't help but it's worth a try. Let us know if you figure it out.

Just stumbled across your question. Is this still a problem? Haven't heard of this happening before. Have you tried the obvious things like restarting the iPad and closing the running apps? Is your memory full or close to full? That can slow it down as well. Check at Settings > General > Usage
