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.

3. Operations
A. Sensor input circuit
[a] Transport path entry sensor (PIS)
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
actuator. The light path is interrupted when document presence.

L
R45 is the current limiting resistor of LED. R67 is the sensor load resistor.
[b] Treatment tray exit sensor (JTES)
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.

L
R46 is the current limiting resistor of LED. R68 is the sensor load resistor.
[c] Bundle exit sensor (BES)
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.
