9.1.4.18 Head/Carriage Unit Traveling Speed Check (Function code 69)
îš„ Function
This function checks whether or not the traveling speed of the head/carriage unit is within the
specified range.
This procedure should be performed when you replace the head/carriage unit or carriage motor, or
when you loosen the CR timing belt.
îš„ Operating Procedure
(1) Press the 6 and 9 keys in this order in the initial stage of the maintenance mode.
The machine starts aging the head/carriage unit, showing the "CR AGING" on the LCD.
In each of travel speeds 43.3 and 21.7 inches/sec, the machine checks whether the maximum and
minimum speeds are within the specified range.
- If both are within the range, the "43O 21O" appears on the LCD.
- If either one is out of the range, the machine shows some message, e.g., "43O 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 inches/sec.; however, it is out of the range at 21.7
inches/sec.
(2) Press the Stop/Exit key to return to the initial stage of the maintenance mode.
