Handling boards
ESD protection All the boards described in the following are fitted, among other things, with
large-scale integrated circuits. Voltage impulses caused by static charging
from people or objects can easily destroy the circuits.
¯ When handling boards, ensure that the electronics cannot be damaged by
static charging or discharging.
¯ Place the printer on an earthed underlay before opening it.
¯ Earth your body with an ESD protective armband or by using another
suitable means. If suitable ESD protection is not available, touch an
earthed object, e.g. a radiator, before touching a board.
¯ Only place boards on an earthed underlay.
Handling The conductor lines on modern multilayer boards are very thin. Bending the
boards can therefore easily break the conductor lines.
¯ Avoid bending the boards.
¯ Avoid using excessive force when removing and installing the boards.

Board setup
Setup all sensors as follows:
1. Select OTHR/SCHK (sensor check) in the parameter menu.
2. Press the CUT- or FEED-key until the parameter corresponding to the
sensor, which is to be set, shows up on the display (column „Display:
parameter“).
3. Arrange the setting condition (column „Setting condition“).
4. Change the setting by turning the corresponding potentiometer (column
„Pot.“) until the reading coincides with the entry in the column „Test point:
value“ or „Display: value“.
Photo. switches • The settings of both types of punch sensors (light transmission and reflex)
are shown on the display.
• The settings of material end sensor, print head sensor and ribbon end
sensor require the use of a voltmeter at the corresponding test point
(column „Test point“).
Mech. switches • The sensors generating the signal for stacker full / stacker hood open are
mechanical switches which don´t require any settings. The displayed value
– 0 or 15, corresponding to the switch position – indicates the correct
function of the switch.
¯ Refer to the values printed with gray background for setting. Make sure to
keep the photoelectric switches clear while setting. The values for
photoelectric switches with inserted material are only listed to counter-
check the setting.
P More detailed information about the parameter OTHR/SCHK can be found
in the subject section „Info Printouts and Parameters“.

¯ From firmware version 1.10 on, or from serial no. 022208 9909 on
(digits printed in italics =continuous no.), the settings for both printhead
versions are identical:
Head voltage JP1 Printhead R25 CN29 26,0 V
Up to firmware version 1.10, the settings for the printheads are different:
Head voltage JP1 8,0-Dot Printhead R25 CN29 26,0 V
11,8-Dot Printhead 23,5 V
¯ Printhead voltage setting only in off-line mode! Setting of the printhead
voltage while the printer is performing a print job is not possible!
