Printer Saga

I took another look at the inside of the printer. There was really nothing I could do except pushing in the detached polyurethane sheet, on which the ink cartridge runs. When I extracted a sheet of paper, which had got stuck unsurprisingly, a torn fragment of paper of several days old came out along with the paper itself. It seems this fragment has been causing paper jamming. Thereafter, the printer started running fine. I hope this solved the problem. However, the thing I don’t understand is that the Service Center failed to find the fragment and left it there. And the “hot liner” I talked to was like a taxi driver who has his own destination regardless what his customer says.
