 +Ein Multifunktionsdrucker, der in der Karmanstr. 7 zur Entsorgung gelassen wurde. Wurde zerlegt und sortiert.
  
 +  * Glasplatte neben dem E-Lab rechts
 +  * [[projekte:contact_image_sensor|Contact Image Sensor]] bei Cracki
 +  * Motoren
 +  * keine Encoder gefunden (war n Laserdrucker)
 +  * haufenweise Lichtschranken
 +  * FFC Flachbandkabel und Sockel (1.0mm)
 +  * Platinen, u.a. eine mit Duzenden von Tastern
 +
 +===== Beschriftungen =====
 +
 +  * 01 70315
 +  * FK2-9569-000
 +    * das ist die Typbezeichnung für den CIS
 +  * 01 57038164 F
 +    * Barcode: Format ITF, Typ Text, Wert 57038164
 +
 +===== Pinout =====
 +
 +  * 6 Clock
 +  * 7 Startpuls
 +  * 8 Vref
 +  * 9 VCC (5V)
 +  * 10 GND
 +  * 11 DPI (low: 300, high: 600, pullup)
 +  * 12 Aout
 +    * 2-4 V Ausgang, geht nie runter auf 0
 +
 +  * regelmäßige blinde Flecke, ca 0.5mm breit jeweils
 +  * doppelt so viele blinde Flecke, wenn Spannung an DPI > VCC
 +
 +===== Reversing =====

 +Pins gezaehlt von innen (links) nach aussen (rechts).
 +
 +Bis auf GND sind 1-5 und 6-12 getrennt. Insbesondere 5, trotz weiterer Abzweigung, scheint mit nix weiter zu interagieren.
 +
 +==== Messungen ====
 +
 +Spannungen bei 10 mA und 3.4V:
