ADVARSEL !

Lithiumbatteri – Eksplosionsfare ved fejlagtig håndtering.

Udskiftning må kun ske med batteri

af samme fabrikat og type.

Levér det brugte batteri tilbage til leverandoren.

(English)

Caution !

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type

recommended by the manufacturer.

Dispose of used batteries according to manufacturer’s instructions.

(Finnish)

VAROITUS

Paristo voi räjähtää, jos se on virheellisesti asennettu.

Vaihda paristo ainoastaan laitevalmistajan suosittelemaan

tyyppiin. Hävitä käytetty paristo valmistajan ohjeiden

mukaisesti.

(French)

ATTENTION

Il y a danger d’explosion s’ il y a remplacement incorrect

de la batterie. Remplacer uniquement avec une batterie du

même type ou d’un type équivalent recommandé par 

le constructeur.

Mettre au rebut les batteries usagées conformément aux

instructions du fabricant.

(Swedish)

VARNING

Explosionsfara vid felaktigt batteribyte.

Använd samma batterityp eller en ekvivalent

typ som rekommenderas av apparattillverkaren.

Kassera använt batteri enligt fabrikantens

instruktion.

PIS is a photo interrupter which integrates a light emitting diode and photo transistor. A document from the copier is detected by the lever-system
actuator. The light path is interrupted when document presence.
The signal is passed to the CPU (IC9-61 pin) through the noise filter of R13 and C17. 
Logic of the signal inputted to the CPU: Document presence

 L

R45 is the current limiting resistor of LED. R67 is the sensor load resistor. 

JTES is the sensor same as the transport entry port sensor (PIS). The document discharged to the treatment tray is detected by the lever-system
actuator. The light path is interrupted when document presence. 
The signal is passed to the CPU (IC9-59 pin) through the noise filter of R14 and C18. 
Logic of the signal inputted to the CPU: Document presence

R46 is the current limiting resistor of LED. R68 is the sensor load resistor. 

BES is the sensor same as the transport entry port sensor (PIS). 
The document on the treatment tray is detected by the lever-system actuator. The light path is interrupted when document is pre sent. 
The signal is passed to the CPU (IC9-56 pin) through the noise filter of R17 and C20.
