CHAPTER 3
ADJUSTMENT
How to adjust the applied energy for the thermal head and the charging time for the battery are given in this chapter.
3.1ADJUSTING THE APPLIED ENERGY FOR THE THERMAL HEAD
Procedure:
1.Check the head rank mark (A, B or C) displayed on the FPC of the printer mechanism
Figure 3-1 Head Rank Mark
3-1
2.Initialize the dipswitches with the following procedure:
1.Remove the AC adapter from the power plug.
2.Connect the AC adapter to the power plug.
3.Power ON the printer while pressing the ONLINE and PAPER FEED buttons on the printer.
4.Release the ONLINE and PAPER FEED buttons after the ONLINE and OFFLINE Iamps blink. It takes approx. 30 seconds.
3.Initialize the applied energy for the thermal head with the following procedure:
1.Prepare a parallel interface communication between the printer and the computer.
2.Send the following command from the computer: ESC + "!" + FF16 + FF16
4.Set the head rank and the dipswitches with the following procedure:
1.Prepare a parallel interface communication between the printer and the computer.
2.2. Send one of the following commands from the computer according to the head rank used:
Head rank |
Command |
A |
ESC + "." + EB16 + FF16+ FF16+ 7316 |
B |
ESC + "." + EB16 + FF16+ FF16+ 7216 |
C |
ESC + ". " + EB16 + FF16+ FF16+ 7116 |
5.Make sure that the printing density is OK by printing a test print.
