interesting to find many bubble jet printers do not use expensive components like stepper motors.
but use what looks like cheap DC motors (have just two wires)
and an odd
0.1mm step 6 pin incremental optical type encoders made by avago part no on the body is N156313.
this type of incremental photo detector array reads the plastic optical shuttle tape or plastic disc
with its 0.1mm stripes pattern as the is not a absolute encoder the bubble jet printer cpu must reset the shuttle by
looking for a dot on the plastic optical shuttle tape end.
its that "cluck" noise when the printer is booted up. to reset the position of the shuttle unit and print heads
I am seeking to know the outputs of the Incremental Pulse but I have no schematic diagrams to help with the pin outs.
my first question is
what is the pin out for the N156313 encoder. can not find a PDF for this.
I like use this type of 0.1mm encoders in my hobby projects. as DC motors are cheaper then stepper motors.
it is the 0.1mm Incremental step and the Incremental Pulse pin output need to know.
i have tested one unit and made a video-
Anyone else salvaged this component, or used this cheap type of 6 pin incremental optical encoder?
do you have a output driver circuit for it? datasheet?
this not the same component. the two images are not the same body or part type as the Canon printer
https://www.broadcom.com/products/motion-control-encoders/incremental-encoders-code-wheelsthe printer switch mode power supply is a sealed unit that outputs 23 volt DC at 600ma
but most of the cheap DC motors run at just 6 volts. so this must be all phase width modulation.
