HP Designjet T2500 eMultifunction Printer series - Manual (Page 65)

If the roll you have selected is already loaded, you have to wait while it is automatically unloaded.
2. If you start to load roll 1 while roll 2 is already loaded, roll 2 is withdrawn to the standby position, so
that it can be printed on again without reloading whenever required (and vice versa).
NOTE: If at any time you open a roll cover while that roll is loaded but not printing, the roll will be
automatically unloaded, and you will have to reload it the next time you want to print on it.
3. Open the roll cover.
4. Load the spindle into the printer, with the blue stop on the right. Hold the spindle by its ends and not in
the middle, to avoid touching the paper and perhaps leaving marks on it.
5. If the edge of the roll is not straight or torn (sometimes due to tape used to hold end of the roll), pull the
paper slightly and cut a straight edge.
