2 07/02 Rev SERVICE MANUAL Service Boards, Page 2 Handling boards ESD protection Handling 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. 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.

6 07/02 Rev SERVICE MANUAL Service Boards, Page 6 Board setup Photo. switches Mech. switches 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. 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 ). 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 countercheck the setting. P More detailed information about the parameter OTHR/SCHK can be found in the subject section Info Printouts and Parameters. Sensor Plug Setting condition Pot.
