(3) Carriage unit replacement
To replace the carriage, the carriage shaft must be removed from the main chassis (by removing the
screws).
Before removing the screws, put a mark on the main chassis to indicate the carriage shaft position. (The
screws are either the red ones or the regular ones.)
After replacing the carriage, return the carriage shaft to the original position while aligning the shaft to the
mark on the chassis.
The screws on the carriage shaft adjustment plate may be loosened only at replacement
of the carriage unit. DO NOT loosen them in other cases.
(4) Platen unit replacement
When attaching the platen unit, perform adjustment to protect the eject roller shaft from bending due to
weight of the spur unit. (The screws to be removed and re-fastened for adjustment are either the red ones or
the regular ones.)
