More on Registration
The paper feed clutch stays on slightly after the registration clutch turns off, so
that the paper buckles against the registration roller.
SP 1003 can be used to adjust the amount of buckling.
The paper feed clutch can come on again to help paper feed get started after
registration. This is a good idea if there are frequent jams at the registration roller
just after registration.
These jams occur when the paper jumps over the registration instead of
going between them. The clutch comes on again for certain paper types,
such as thick paper, to try to push the paper between the rollers.
SP 1903 adjusts this feature.
In lab tests, this problem was not found when feeding from tray 1. So there
is no adjustment for tray 1.
