Printer gone funny - can you help?

[joegina]

My printer (Epson DX 4050) prints with lines missing. The effect is that letters and numbers have bits missing. Not enough to make them unrecognisable. Funny thing is that if I copy a document, it prints it fine. I have connected it to 3 computers (2 PCs and a Mac) and it's the same every time. Things went wrong after a paper jam. Tried reloading the printer software to no avail. Help?

You don't say if you have checked the cratridge(s) or tried nozzle cleaning, which are the first things. I had a similar problem the other day and had to do this. These are usually avilable from a menu in the printer software.

agree - it's either blocked nozzle - or the connector on the cartridge

do as post says first ... if not clean the contacts

if still no joy ... I have been known to cover the print head(s) with a wet tissue for a cuple or so minutes

but only as a last resort ... the cartridge will suck the moisture - and hopefully dissolve the blockage (prints could be a bit washed after)

last resort .... 90% says a new cartridge will sort it ...

Thanks guys. I did run all the checks to no avail. However, I removed the black cartridge, shook it and put it back. All is now well :-)
