* Do not leave the media on the platen unattended. It may cause the media to become uneven.
* When not in use, please raise the clamp lever and keep the pinch roller and grid roller separated.
Leaving the pinch roller lowered for an extended period can cause deformation of the pinch roller.
If the pinch roller deforms, there is a risk that the media may not feed correctly.

[Important]
Please check the following to prevent ink path clogging and to protect the nozzles.

(1) Please keep the main power switch on during long-term storage.
The nozzle clogging prevention function works automatically to protect the printhead nozzles.
Leaving the main power turned off for a long period of time may cause the nozzles to be clogged.

(2) Check the remaining amount of ink packs and maintenance cleaning liquid cartridges.
During the cleaning operation, suction of cleaning liquid and ink will take place.
During ink suction, nozzle wash does not start if "INK END" or "INK NEAR END" is detected.
During the idle period, regular maintenance consumes ink and maintenance cleaning liquid.  
Therefore, it is recommended to set maintenance liquid cartridges and ink packs
(approximate weight 400g or more) with sufficient remaining quantities.
If the remaining amount is low, please replace the maintenance liquid cartridge and ink pack.
