HP 1050 troubles

Hello there
I have this problem at a costumer, working on Autocad 2004 Service Pack 1a,
windows XP Pro and an HP 1050c. They a custom paper that is 2000mm long, and
if we try to plot a draw, that is much smaller, the plotter cuts the paper
when the draw is all plotted and doesn´t spend the 2000mm. I believe this is
the inked area option. The problem is if you try to plot 2 or more copies
from a draw like this it only works fine in the first draw, after that the
plotter rolls out the 2000mm of paper and then begins to plot again.
any ideas?
Thanks In Advance

 

Mine does this with long custom paper size plots as well - it has done so on
Win95 with 2000, Win2k on Autocad 2k and Autocad 2k2, and WinXP with AutoCAD
2k4 - Driver versions 4.61-4.63...

I just don't try to plot multiples. It would be interesting if someone has
found a solution.
