More often than not its due to the blades becoming blunt, the majority of shredders have the middle\centre blades go blunt first, this can cause blockages, and also paper to be pulled unevenly.
Once they have gone blunt its not really economical to get them sharpened, and alot of the sharpening 'sheets' you run through them doesnt really work from my experience.
However before residing to the fact the blades are blunt, I would be inclined to strip the unit down (with it unplugged), and make sure there arent any staples, or debris stuck in between the two drums, then give it a good oil. Sometimes you cant see a blockage until you take it apart, and spending 20 minute giving it a clean up can bring it back to life.
Please let me know how you get on.
Good morning do you still require assistance?
No problem Brian, will await to hear back from you.
Hi Brian, how did you get on with the repair?
Good morning Brian, I havent heard from you in the last couple of days do you still require assistance. In order for me to close the case I need you to rate the service received using the star rating on this page.
Brian its all hit and miss, I have serviced and scrapped shreaders costing £500 and those costing £50, by in large its pot luck a good brand may have a poor design. Ive got a cheap £50 one which has been going strong for 5 years, but also know ones which costs 100s (and get same amount of use) die after 18 months.
I cant really offer another solution if you have serviced the unit, and checked everything is aligned, sharp and free from obstruction.
Hi Brian, I havent heard back from you, do you require any further assistance?
If not appreciate if you can rate the service received, so I may close the case
The one I have is a AT-8X by Ativa, its used daily and can handle paperclips, cd's, dvds etc and also shreds to DIN3 specification.
Its currently being sold here for under £40, the only limitation I have with it, is if you feed 6-8 sheets one after the other for 2-3 minutes, it soon locks out for 15 minutes to let it cool down.
No problem Brian, appreciate if you can rate the service received today so I may close the case.
