Question about HP OfficeJet 7310 All-In-One InkJet Printer
Hello, the problem is there are 2 sensors that could be causeing this problem there is an optic sensor on the carraige unit, on the right hand side. with power on, open cover as if you are going to replace ink, pull power cord out of printer, move carraige over to left, with a moist paper towel, i would clean the optic sensor, only the lower portion of this area, the area that glides over the paper, make sure you do not pull on the white or by now blackish color on the electronics, this can get damaged easily. go ahead and close cover and power up, and try again, now the other sensor you have to look at is the one that you will be able to see from the back area of the machine, when you remove the duplexor, if one is added to machine, or back cover. it is located on the left hand side in the upper area, it hangs down, use compressed air in this area, make sure that this flag moves freely. if you checked everything, then the machine will need carraige unit, replace it with the exact same machines carraige. since there are about 4 types of these carraiges out there.
