1.4.23 Traveling Speed Check of Head/Carriage Unit (Maintenance mode 69)

<Function>
This function checks whether the traveling speed of the Head/carriage unit is within the
specified range.
<Operating Procedure>
(1) Enter [6] and [9] in the initial stage of the maintenance mode.
The machine shows "CR AGING" on the LCD and starts checking the traveling speed
of the Head/carriage unit.
In each of travel speeds of 43.3, 26.7 and 21.7 inches/second (ips), the machine
checks whether the maximum and minimum traveling speeds of the Head/carriage unit
are within the specified range.
- If the maximum and minimum speeds in all of the three traveling speeds are within
the specified range, "430 270 210" appears on the LCD.
- If any one is out of the range, the machine shows some message, e.g., "430 270
21X," on the LCD. This sample message indicates that the speed variation is within
the allowable range when the Head/carriage unit travels at 43.3 and 26.7 inches/
second; however, it is out of the range at 21.7 inches/second.
(2) Press [Stop] or [X] to return the machine to the initial stage of the maintenance mode.
