Stoppable Period and Long-term Shutdown
CAUTION
Since "Perform long-term shutdown storage work" requires special work, it is recommended to contact
your local distributor and ask for the work.
[Remark] "Days printer can be stopped" depend on Ink model.
Please refer to the attached document for each ink.
If the IJ printer is not operated on regular basis, ink may stick in circulation system. If it sticks, error such as ink not ejecting and
ink can not be recovered are occur. To prevent these issues, refer to "IJ printer Stoppable period (*1)", and operate IJ printer (eject
ink from the nozzle) on a regular basis. The period that can be stopped depends on the storage temperature. Also, please note
that the period may be shorter dramatically depending on the usage environment(*2).
In case of long period shut down more than the term shown in "Stoppable period and Long-term shutdown", to operate "Long-
term shutdown" is necessary. This long-term shutdown prevents sticking by draining the ink in the IJ printer and filling makeup
(solvent) instead. Dedicated operation is required even when restarting. Please refer to the [Technical Manual (* 3)] for details of
the operation.

replacement intervals vary with the printer operating environmental conditions (temperature, humidity, dust, etc.). Please
determine the best replacement cycle in accordance with the obtained printing results, and replace all ink in the printer with new
ink.
