Welcome

I have a machine PRO 1051 and PF-703

According to the specification of the appliance are available Max. paper size: 324 x 463 mm.

According to the specification of PF-703 with PRO 1052 is available Max. paper size: 324 x 483 mm.

I wonder whether it is available some DIPSW or something that would allow me to have format
Max. paper size: 324 x 483 mm to PRO 1051.

Greetings
