7.5.16 Initial Adjustment of PWM Value (Aging of the Carriage)
Function
This function obtains the initial value of the PWM by aging the carriage and writes it onto the
EEPROM, as well as checking the head drive voltage level.
This aging procedure should be performed if you replace the print head, carriage ASSY, carriage
motor, or encoder strip or if you loosen the timing belt.
NOTE:
Opening the scanner unit during the aging procedure will result in an error. If you
perform this aging procedure with the scanner unit opened, the equipment will slowly age the
carriage resulting in an error after completion of the aging.
Operating Procedure
(1) Press the
6
and
9
keys in this order in the initial stage of the maintenance mode.
The equipment starts aging the carriage, showing the "CR AGING" on the LCD.
After writing the initial value of the PWM onto the EEPROM and checking the head drive
voltage level, the equipment automatically returns to the initial stage of the maintenance
mode.
If any error occurs, the equipment beeps and shows some message, e.g., "OK30 NG15 NG07"
on the LCD. This sample message indicates that the speed variation is within the allowable
range when the carriage travels at high speed of 30 inches/sec.;however, it is out of the range
at medium or low speed of 15 inches/sec. or 7 inches/sec.
To return to the initial stage of the maintenance mode, press the
Stop
key.
