Ricoh P502 - Bypass custom size

[stewietopg]

Hello,

we have a Ricoh P502 and i have trouble setting up bypass tray. In Tray 1 we print normal A4 paper but in bypass tray we have small 13 cm x 13 cm paper that we use in our warehouse.

Problem is that i dont know how to set up that when printed document is A4 print from Tray 1 if it's the small one than use bypass tray or if it's possible that if printed document is any custom size than use bypass tray beacuse some documents are printed directly from program and program sets size 13cm x 13,9cm and if i try to print that i get error.

Any tips how can i fix this?

Thanks
