Omnitech shredder manual
Given this, I surmised that the medium circuit board was the 'logic' for the shredder and that two relays on this circuit board switched the 120v mains power to the motor on and off.

As the shredder chassis was open, I could clearly see the TZ-7040M12 high torque motor inside it was rated for 120V/60Hz AC. The problem as it stood, was this - when power was turned on and paper fed in, the motor did not work and the shredder's LED status light did not illuminate. Movingįorward I relied on what little I remembered from school electronicsĬlasses, the ability to use Google to find information and a $10 digital Up until this point I knew what I was doing. I'm far from an expert in electronics so anything beyond checking the continuity of the fuse is usually a challenge. Inside Omnitech's OT-EMC7A shredder is a small circuit board behind the top switches and a medium sized circuit board with an integrated circuit, a fuse and some relays and assorted electronic bric a brac. The primary power switch and safety interlock switch with a simple continuity After that failed to resolve the problem, I worked backwards from the power plug (*while unplugged*) to check the functionality of The next step was to check the internal wire harnesses for loose connections. Scraps of shredded paper so I removed that clutter and used tape to seal up theĪrea so the same issue couldn't reoccur. Paper slot to sense when paper is being fed in. A pair of infrared LEDs are used in this shredder by the Using a phillips screwdriver the fasteners were removedĪnd the case opened up. Since it wasn't overheated, the next step was to look for a paper jam inside the Omnitech OT-EMC7A shredder. The most common issues were overheating motors and paper jams in the shred feed sensor. was there a visible paper jam? With no issues on all these counts I turned to Google and researched common shredder problems. was the safety interlock switch triggered by the waste paper basket. Being out of warranty, I took a stab at fixing the wee beastie.įirst I checked the simple things was it plugged in. If the warranty is expired and the only alternative is the garbage bin, why not try to fix it yourself?Ĭase in point - The Broken Staples ShredderĪ few weeks ago our inexpensive $50-dollar Omnitech OT-EMC7A micro cut paper shredder from Staples.ca gave up the ghost and stopped working. My point is, even if you only have two of the three fundamental aspects of this problem covered - say fresh AA batteries and hands to open up the remote control - you can usually solve the third (knowing the batteries need to be changed). In this scenario your hands are the tools, the local drug store is your resource for batteries and your knowledge base tells you that once the remote control's power supply runs down, it's time to change it.

I think it fundamentally comes down to having the right knowledge, proper tools and resources (in this case, parts).Īs an over-simplified example if your TV remote control stopped working you would remove the batteries, get new ones and make it work again. In answering that question, go beyond the superficial stuff and distill the problem down to it's elemental aspects. Stop, really think about that question for a moment. If your consumer electronics break, what's stopping you from trying to fix it yourself? so PCSTATS is going side-step that quagmire and simply pose a question to you. PCSTATS is going to divert from our usual crop of fantastically in-depth motherboard reviews and discuss for a moment, the topic of busted consumer electronics.Ĭhina is without a doubt the punching bag of the world when it comes to complaining about electronics that prematurely break, but isn't this because the overwhelming majority of consumer electronics are manufactured in this country? Now a debate on nationalist manufacturing pride is beyond my pay grade and inevitably everyone walks away angry.
