Hat geantwortet auf: How to test ear speaker on iOS 12 revamped voice memo app?I found a solution for this. There is a free app called Test M. It tests everything on the phone. You don’t have to do all the tests if you don’t want to. You can just select the hardware icon and then test the ear speaker. A voice will say three numbers thru the ear speaker. They then want you to put the numbers in so the app knows it worked, but of course if you hear it, then your test is over.
Hat geantwortet auf: How do I fix a printer headWelcome to the club! There is a chronic problem with this printer's printhead. HP will send you another one and it will fail soon also. I am on my 2nd one now. Each of them lasted about 6 months. The REAL problem is an over sensitive method of determining that there is a problem with the printhead. This is why I know this to be true. Both times, I was able to get the printer working again, several times, for a little while by restarting the printer and/or removing and replacing the cartridges. Every time I got it working again it printed PERFECTLY until it cam up with the message again. So therefore, there is either nothing wrong with the print head or whatever is actually wrong with it is so minor it doesn't matter. SOLUTION: HP should (but probably never will) update the firmware over the internet to prompt us if we want to print anyway. Then if the printer prints fine, everybody's happy. If not, then there really is a problem that needs to be fixed.
