While the printer is switched off at the front panel, it may automatically unload a roll in order to maintain
the paper in the best possible condition. This is done only with certain specific paper types (film, glossy
paper, and heavyweight coated paper).
The printer unloads the paper when switched on [4500]
NOTE This topic applies to the HP Designjet 4500 Printer series only.
If the printer is switched off using the switch at the rear, or by disconnecting the power cable, or by a
power cut, whenever it is switched on again it may automatically unload a roll in order to maintain the
paper in the best possible condition. This is done only with certain specific paper types (film, glossy
paper, and heavyweight coated paper).
CAUTION If you want to turn off the printer, you are strongly recommended to use the Power
button on the front panel before using the switch at the rear or disconnecting the power cable.
