What to Do If the Printing Carriage Does Not Operate

Capping the Heads

It is necessary to move the carriage to the standby position and cap
the heads manually because the motor controls the up/down
movement of the capping system. (SC-500 : mechanically controlled)
User's Manual says :
During operation, if for some reason the printing carriage does not return
to the standby position, then follow the procedure, cap the printing heads,
and contact the your authorized Roland DG Corp. dealer or service
center.
If the printing carriage is allowed to stand for a prolonged period with the
printing heads uncapped (that is, with the printing carriage over the
platen), the heads may become clogged or even damaged.
