As I have done many times for years, to save paper printing a 20 x 3.33 cm image, I put a 21 x 8cm strip of photo paper into the back of the printer set for A4 paper, told Photoshop to print it at the top of an A4 sheet, called it an A4 portrait in Page Setup, and clicked Print. The strip of paper slid into the bowels of the printer, it sounded as if the image was printing but then vanished, and the paper jam warning came up. I've taken the back of the printer off, peered into the printhead cavity and can't see the paper anywhere. Can anyone help please. I really don't want to have to buy yet another printer. Thankyou
