Thick dashy dark patchy breakups in printing

[archz2]

I'm using HP Laserjet 1018 Printer. For the past six months i'm having problems in printing. If i print lets say page 1-20 of a particular document, i get two partial pages printed on one sheet with black noisy strip in between (See image). This doesn't happen in the whole print set. This happens only in last two pages in one printing set.

So if i print 1-20 the problem will be there in pg 19,20. The rest of the print set will print fine. or it may get like 15,16 and 19,20.

I uninstalled my driver too and reinstalled it but the problem is still there. I was using windows 7 [32 bit earlier], but now i switched to 64 bit version. Hence i installed the 64 bit version of the driver. But the problem is still there. I asked the printer repair guy, but he can' figure out what's wrong.

Hello,

Thanks for the post.  With this one, is it possible that the file itself is corrupt?  Is it possible to copy the file and paste into a new document or even a different text editor?  Do you have these symptoms with any file over 20 pages?  What happens if you break up the print job say, print the first 10 pages and then the last 10 pages?  I've included a link below with some excellent t-shooting information and steps to resolve.  Good Luck!

This happens with all the documents and in all softwares, be it coreldraw or adobe reader or foxit reader. even if i give command for 10 pages, the problem creeps in last 2 pages.
