When the maintenance call error occurs
A maintenance call warns you to replace the consumables with a new one very soon. If MAINTENANCE
CALL NNNN is displayed on the LCD panel, contact your dealer and tell them the maintenance call code. If
you continue to use the printer, the service call error occurs.
When the service call error occurs
A service call error occurs when:
❏ The power cord is not plugged properly into the electrical outlet or the power connector of the
printer.
❏ An fatal error has occurred.
When a service call has occurred, SERVICE CALL ERROR NNNN appears and the printer stops printing. Turn
off the printer, and then check that the power cord is plugged properly into the electrical outlet or the
power connector of the printer. Plug the power cord properly and then turn on the printer. If the service
call error is cleared, you can continue to use the printer. If the same service call error is displayed on the
LCD panel, contact your dealer for assistance. Tell them the service call code is "NNNN".
