Hacking Flatbed Scanner Components Answered

I am currently working on a project which was going to use a scanner to acquire an image. The scanner is/was an HP 6200C. When I was trying to modify the scanner I accidentally broke the lamp, but was then excited to discover [what I believe is] a linear photodiode array which functioned as the detector. (I also found some cool mirrors and a focusing lens inside.) This photodiode array could be very useful to my project. 
This scanner interfaces with my computer through USB, and refused to work after I unplugged the lamp.
I figure a resistor may trick the circuitry into thinking the lamp is still attached, but I no longer require the moving parts of the scanner at all; I only want the photodiode array and a way for it to interface with the computer, preferably giving either a "single line" type image or a "single really thick line" type image. (Basically I just need intensity and location of signal. If the received data is a full image, I can reduce it to what I need.)

Does anyone have any experience or suggestions for me? I have uploaded a few pictures of the relevant circuitry and can add more upon request.

Update: After further research, I've determined that it is not a photodiode array but a linear CCD.
