Traveling Speed Check Of Head/Carriage Unit (Function Code 69) - Brother DCPJ525W Service Manual

1.4.24 Traveling Speed Check of Head/Carriage Unit (Function code 69)

Function
This procedure checks whether the traveling speed of the head/carriage unit is within the
specified range.
Be sure to perform this procedure if you replace the head/carriage unit, carriage motor or CR
encoder strip, loosen the CR timing belt, or apply lubricant.
Operating Procedure
(1) Press the 6 and 9 keys in this order in the initial stage of the maintenance mode.
The machine shows "CR AGING" on the LCD and starts aging of the head/carriage unit.
In each of travel speeds of 57.7, 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 four traveling speeds are within the
specified range, the "57O 43O 27O 21O" appears on the LCD
- If any one is out of the range, the machine shows some message, e.g., "57O 43O 27O
21X" on the LCD. This sample message indicates that the speed variation is within the
allowable range when the head/carriage unit travels at 57.7, 43.3 and 26.7 inches/
second; however, it is out of the range at 21.7 inches/second.
(2) Press the Stop/Exit key to return the machine to the initial stage of the maintenance mode.
