Resolved Question:

getting service error 5100 on my canon PIXMA MP 450.

the 5100 is the carriage error and can be caused by 4 different sensors.

First off the "Timing Strip" that passes through the back of the Carriage Assembly can be contaminated with ink spots and this needs to be cleaned. Open the cover and use your flashlight to examine the timing strip as much as you can see.
You really don't have much access to this strip unless you remove the covers,..and doing that is considerable work. The other items that can cause this error are the sensor inside the carriage unit, the drive motor for the carriage asm, and of course the main logic card. However, 99.6% of the time it is the Timing strip which is easitly contaminated with splattered ink.
