The facts that the optical sensor is ok, and a high wattage resistor gets hot, indicates a mechanical problem, i.e. it's actually stuck (there may be a different power rating in the cpu, that means that by automatic, it stops by for example 1 Ampere, but by manual, there is no current check, i.e. the cpu delivers what the power supply is able to give. could be several A's, which will in turn burn the motor if you try the manual too long....) So, unplug the power cord, and try to move the mechanics by hand, and you will discover the problem.

In case of a paper jam , which may occur if the shredder is pushed beyond its specified capabilities, press the control switch to the off [O] position and empty the basket if full. Then:
1) Press and hold control switch in reverse [R] position and attempt to back paper out of shredder.
2) If shredder jams in reverse mode, press control switch to automatic [I] position and attempt to continue shredding operation.
3) If shredder jams again, alternate control switch slowly between reverse [R] and automatic [I] positions to attempt to move jammed paper completely through shredder.
If you are unable to clear the jam using this method, turn off and unplug the shredder; remove the wastebasket from cabinet and carefully remove any paper extending below the cutting cylinders; empty the waste basket; insert waste basket and repeat jam clearing procedure.
I see that the unit runs when in Auto position.
First make sure you turn the machine OFF then see if there is anything in the way of the shredder that gets detected by the sensor.
That can be one reason why it keeps on running when in Auto.
To reset turn the unit OFF and unplug it from the wall outlet or power source then hold down the power button for at least 5-15 seconds then plug it back in then turn or power the unit back up.
Still make sure that there is no paper debris anywhere in the way of the sensor.
I hope this helps.
I got mine to work by running it on reverse for a moment then sliding it to auto. It stopped. Then I did it again. This time auto ran just for a second then stopped. I did it a third time but I had a sheet of paper ready in the feeder. Ran on reverse. Slid it to auto and it took the paper and shred it. I did it a fourth time. Reverse slide auto and feed shred the paper. Fifth time Auto shred the paper without reverse. :)
Ensure the wastebasket is empty then move power switch to the REVERSE position. This will reverse the jammed paper out of the shredder. If shredder jams again, alternate control switch slowly between REVERSE and AUTO (l) positions to attempt to move jammed paper completely through the shredder. If the shredder jams in reverse mode, move the switch to AUTO (l), depress the manual forward button located on the center of the shredder head and allow to run for five seconds. If jam does not clear, move switch to REVERSE again and allow to run for five seconds.
Repeat this process until jam is cleared. If necessary, turn off shredder and use care to grasp the paper and carefully pull out to clear jam. Once cleared, move switch to AUTO (l) to continue shredding. The jamming may be happening because the cutting cylinder needs to be oiled.
Follow instructions to oil your shredder;
To keep your shredder in top condition, the cutting blades need to be oiled every so often (for frequency, please refer to your owner's manual). We recommend using Powershred® Lubricant or a vegetable-based oil (such as corn or canola) in a non-aerosol container with an extension nozzle.
Caution: Never use flammable synthetic oil, petroleum-based, or aerosol lubricants to oil the cutting blades. Some agents may combust, causing serious injury. NEVER USE WD40.
1. Depress and hold the reverse button down. 2. Put the tip of the oil bottle in the paper entry and make one or two sweeps the length of the entry while squeezing the oil bottle. 3. Move the power switch to Auto (I) position, or depress the manual forward button (depending on model of shredder) and allow the blades to run at least three seconds. 4. Move the power switch to Reverse (R) position and allow it to run for at least three seconds. 5. Repeat steps three and four above at least three time.
Chances are it's over heated.

Inside the shredder there is a motor which is wired to run both forward and backward, the way it does this is to transfer the power from the switch to a couple of wires on the motor
The forward running motor will be linked to the auto start button which will tell it to work with the paper sensor.
When you select the Forward function the Auto Start is taken out of circuit and the Forward switch should supply the motor
After all of that I would say that the switch is open circuit on the Forward contact and needs replacing
This is an issue with the paper feed sensor which may be a electronic eye or a mechanical switch if it is mecanical you may just have to jiggle the switch a few times, occasionally paper may get stuck behind it not letting it activate. If it is electronic you have bad sensors or bad pc board and you'll have to contact the manufacturer for further info.
I personally work with Fellowes brand shredders, but it sounds like you have a paper feed sensor issue. This may be a mechanical or electronic sensor located in the center of the paper feed slot. If it is electronic it may just need cleaning(qtip dipped in rubbing alchohol. If it is a mechanical sensor check to make sure it has not been broken or it may be stuck because of paper that has become wedged behind it(you may need to jiggle the switch a few times to free it). If none of this works you may have a burned out switch or a bad pc board, contact manufacturer for more info.
