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, the "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.
