Carriage lock release
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 in one of
two ways:
a) On the back of the printer, push down the purge unit's locking pin.
b) On the front of the printer, rotate the gear as shown by the arrow in the illustration
below so that the locking pin goes down.

Handling the purge unit
Note the following with regard to the purge unit:
(1) Grease soiling the blade
Due to the blade's height, the carriage guide shaft may touch it when the shaft is
removed or installed. Grease may soil the blade as a result.
You must not allow any grease or oily substance to adhere to the blade.
(2) Replacing the blade cleaner
When replacing the purge unit, also replace the blade cleaner at the same time.
Since it is soiled by ink, the blade cleaner needs to be replaced.
