Epson Epson Stylus Color 1520

Mysterious lines appearing on Epson 1520 outputs

I've gone through the message boards but can't find an urgently-needed answer to my problem: I've had my Epson 1520 printer for YEARS and just yesterday I began to have a problem of vertical, hairline mechanical lines appearing in places on my outputs. They are definitely not part of the art I'm outputting and it's not a dirty nozzle head issue either (because the lines look computer-generated). Does anyone know how to solve this issue? Of course, this is happening at a time when I have an extremely time-sensitive deadline. Many thanks to all responders!!
