3.3.1 Carriage lock release

NB: When releasing the carriage lock of the S900/S820, it is necessary to remove the
printer unit from the bottom case unit.
Normally, when a cartridge is installed on the carriage and the power is turned off, the
printer moves the carriage to the capping position to lock it. When the power is turned
on, the carriage lock is normally released. However, if the printer does not operate
properly, you can release the carriage lock manually.
On the front of the printer, rotate the gear as shown by the arrow in the illustration
below to release the carriage lock.
