performing maintenance.
2. When performing works de scr i bed in this manual, do not co nnect to a power sour ce unt il i nst ructed to do so.
Connecting to a power source causes high voltage in the power supply unit and some electronic components
even if the product power swi tch is of f. If you need to perform t he wor k wit h the power cable connected t o a
power source, use extreme caution to avoid electrical shock.
WARNING
Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.
1. Always wear protective goggles for disas sembly and reassembl y to prote ct your eye s from ink in wor king. If
any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.

To recover from the maintenance error, the dedicated software that can be downloaded
from the web site which can be accessed from STM3 is required.
The printer operation related to the maintenance error recovery is as follows.
• When the waste ink counter reaches the threshold value (1) for the first time and the
maintenance error occurs, the counter threshold of the maintenance error is changed
to threshold value 2 after performing recovery from the maintenance error.
• After the threshold value (2) is enabled, the warning; to notify the possibility of ink
leakage out of the printer, is displayed every time the waste ink counter increases by
1%.
• If the was te ink counter reaches the t hreshold val ue (2), the ma intenance er ror occurs.
Then, the waste ink counter is changed back to the threshold val ue (1) after reco vering
from the maintenance error, and the warning is displayed repeatedly according to the
increment of the waste ink counter until the maintenance error occurs when the
threshold value (2) is reached.
(Recovery from the maintenance error can be performed up to the specified number
of times.)
