The hot roller and pressure roller have a slight spindle shape. The circumference at the
ends of the rollers [C] is slightly larger than the circumference at the centers [D]. This
arrangement ensures that there is always sufficient pressure on the paper between the
roller ends.
However, this difference in circumference also causes a small difference in the speed of
paper feed. The paper transport speed at the ends is slightly faster than at the center.
Because the centers of the rollers bend in slightly, this also increases the risk of slippage at
the center with paper narrower than 420 mm.
!
For operators who frequently use paper wider than 420 mm, do the sub scan
adjustments for the LPH joints with SP2952-11, -12.
!
For operators who frequently use paper that is less than 420 mm wide, do the sub
scan adjustments for the LPH joints with SP2952-51, -52 after you input the values of
SP 2952-11 and -12 from the decal.
