(13) Recover the data from the USB memory by using the copy data function.
(From the USB memory to the IJP)
As for the copy data function, the user mode and the service personnel maintenance
mode are different. When replacing the EZJ126, it is necessary to back up the
unit-specific data, and so put it into the service personnel maintenance mode and then
perform the backup.
-User mode: User data (printing data (Note 1), substitution rules, user patterns)
-Service personnel maintenance mode:
User data (same as above) and unit-specific data (Note 2).
-After replacing the battery on the EZJ126 board, turn on the power of the IJP
and set the date and time. Perform set up again if it shows wrong date or time.
(Note. 1) The print data are the print description, the printing specifications, the print line, the print format,
the print condition and the count condition.
(Note. 2) The unit specific data are the ink type, the nozzle diameter and the viscosity calibration data.
In the case where the EZJ126 board is replaced in a state allowing NO backup, follow the
-
procedure below.
[ Replacement procedure of EZJ126 board in a state allowing NO back up]
(1) Turn off the power.
(2) Open the control panel and remove connection cable and battery on the
EZJ126 board and EZJ125 board.
