I must have had an eye blink of less than total attention to my *#!%*# unreliable Epson SX600W printer with its ridiculously sensitive paper feed, and it scrunched up a paper which after two or three hours manual contortion somehow in its ridiculously inaccessible insides I was luckily able to remove.

It is now printing a few lines perfectly well then a few lines are missed, then a few more centimetres well, then a few blank or a trace of a faint line etc.

I have gone through the cleaning nozzles etc. routines that I found on the ptrinter (first time I ever did). Cartridges are new and I have never used any but Epson's.

I have spent hours on this, and trying to find anything in manuals.

Does anyone know anything a normal (i.e. not technically adept) person can do about it?

If I have to take it in for the nth time to the Epson agency where I am I think I will ditch it and buy a new printer, it will certainly be faster than the weeks they will take to repair it (even a trivial thing GOES in a queue). But a bit of a waste, as the PRINTED lines suggest there is only something rather trivial wrong and could print as well as it ever does, on the occasions when it prints at all.ANWERED OWN QUESTION!   

In case anyone else ever has this problem and chances here:

I could not find anything on any site

On Epson's own site it was damned difficult to even find the model - it did not appear in their enormous lists. It looks like it is a model that was sold only in Europe, or in the AMERICAS it has a different name or number. Anyway I finally traced it in an Italian Epson site.

I won't go into that. 

At length I was told the answer by a guy in the shop where I buy the Epson cartridges.

I had been cleaning it as described, and as that did not work I cleaned it again and again, several TIMES and it never worked. The guy told me don't do that, it actually clogs it up. Just do it once and leave it overnight. So I did that then cleaned it once, and now after three days it is working!

For now, for today. Maybe everybody but me already knew this.  Still, printers really are the weakest link for COMPUTER using.

Over the years I have went through many printers.
I know your pain.
Presently I have on of the HP all-in-ones. It has its one set of issues But the price was right..
