product.
DANGER
Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.
1. Always disconnect the product from the power source and peripheral devices when servicing the product or
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.

4. Replace malfunctioning components only with those components provided or approved by Epson;
introduction of second- source ICs or other non-approved components may damage the prod uct and void any
applicable Epson warranty.
5. The capacitors on the Main Board may be electrically charged right after the power turns off or after driving
motors which genera tes cou nter e lectr omot ive for ce suc h as when rota ting t he PF Roll er or when movin g th e
CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the c apacitors on
the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the
printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/
reassembly.
6. To prevent the circuit boards from short-circuiting, be careful about the following when handling FFC or
cables.
When handling FFC, take care not to let the terminal section of FFC touch metal parts.
When connecting cables/FFC to the connectors on circuit boards, connect them straight to the connectors to avoid
slant inser t ion.

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 af ter 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), th e maintenan ce error occur s.
Then, the waste ink counter is changed back to the threshold val ue (1) after reco vering
from the maintenance e rr or, and t he warni ng is di spl aye d re peat edl y acc ordi ng t o 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.)
