Printer (Kendal LA9)

HP ENVY 5530 All-in-One Series. This has been a brilliant printer but, recently, has started to 'jam' each time. When I investigate the paper doesn't appear to be 'jammed'. It would be a shame to bin it if there is someone out there who can solve the problem.
I need to get in touch with the gentleman who received this. (I accidentally deleted his e-mail). I have found a disc and some paperwork that should have been with it. Please contact me if you read this. Beryl
