View source for Adjusting print positioning on a risograph



Reference: MF technical manual pg 535 (print position adjustments); these instructions are for the MF and may be different numbers or not available on other machines.

# Enter test mode: hold left/right arrows on position adjustment control panel for drum one, turn machine on. 
# If you consistently need to adjust the print position a certain amount (like always 1.5 mm towards you and 2.5mm towards the lead edge), change the position of 0,0 on the master making using the test mode. For the MF, our adjustments are:
#* 0541 Vertical position = (-7,+3) This setting adjusts the default center position of the master on the long dimension of the paper (17in). It is in tenths of a millimeter.
#* 0586 Horizontal position = (+20, +13) This setting adjusts the default center position of the master on the short dimension of the paper (11in). It is in tenths of a millimeter. Positive is toward the front of the machine. *This seems to be getting reset on our machine sometimes. Not sure why. Sometimes you just need to go in and set it back to (+20, +13).
# If your stencils are coming out shrunken in the direction parallel to the feed, you can adjust in test mode so they are the correct distance. (This adjusts the speed the masters feed through the master making unit.) Make a “test fixture” design with “known” dimensions you can measure, and then make prints measure them. Adjust and reprint until you’ve dialed it in correctly.
#* 0547 Vertical elongation/shrinkage = (0,0) for MF
#* This setting changes how long the prints on the masters are on the long dimension of the paper (17in). It is a percentage.
