konica 7050 deletion on legal size paper

[mdm7266]

hi there, my problem on konica 7050 is that even though the paper size is correct, indicates on upper tray is 8 1/2 x 14 the image is deleted on the rear side, as if it senses a short bond paper which is 8 1/2 x 11. this happens on trays 1 , 2 and bypass tray.

but if i'll used the program mode 47-93 then make copies, it reproduced good and correct images, no deletion.

on normal mode this deletion occurs. what might be the problem here?
i tried and check the program settings on all trays, they are correct.

before this problem happens, the machine problem is a reduced copies, then i cleaned the main motor bearings, and also the fixing rollers bearings that might help the motor to rorate smoothly. i adjust the horizontal magnificaion to correct the ruduced image then i got the exact copy of the original. the next problem now is what i said above the deleted rear copy. does anyone encountered this problem?

Does this happen from both the DF and platen glass?
Is APS/AMS on?

yes it happens on both adf and platen glass.

Anyway, i have already solved the problem, its the program mode 25-70
i changed the value of the data.

thanks

i have a problem with mode 47-94. before, whenever i enter into 25-94 mode, i can scroll the different programs like charge, separation, loop, etc.
but now, when i enter 47-94 mode, the panel does not display of what it use to display before, it only display - output check mode 94.

does anyone know of what program will i set to return the previous display of mode 25-94?
