I've got a samsung scx-4300 which today has decided to break. It's out of warranty by 1 month (typical!) so I thought I'd go a d repair it myself.

The problem is that the scanner part of the printer is caught on something causing the printer to report a system error on it's self checks.

The thing that is concerning me is; would there be any big ass caps that I have to watch out for, particulary around the power supply which seems to be unshielded from the rest of the printer.

No one is around so if I get a shock that knocks me silly I won't be discovered for at least a month. :p
Has anyone else repaired a toner printer or have and safety tips for me?

Thanks. :)
 
As soon as I opened it up I was greeted by 2 large 2uF caps. I'm leaving this thing way alone for a few days. :p

Unless I can discharge them?
 
Leave it off and unplugged for a few hours and the caps will discharge naturally, and you should be fine.

Depending on the age I'd be more worried about physically damaging the caps if they are nice big drying up electrolytics!

Is this a joke?

I would be sending it back to the supplier for repair if it is only 1 month out of warranty.

Nah, samsung have been pretty strict for me in the past. :(

A large good quality capacitor can in theory hold enough charge to give you a good shock for days.

Well if I don't reply in this thread tomorrow, you know I'm dead.;)
 
Depending on the age you'd usually be fine. Just don't break it right down into component parts, all the modular bits will be safe.

Depending on how much you paid, and also the length of the warranty, you could argue that the printer should be expected to last longer than the said warranty. i.e If you paid £300 for something that had a 12 month warranty and it broke after 13 months, you could argue that it should be expected to last longer.

The following statements are frequently made by retailers and are untrue:

Your 12 month warranty has run out, nothing further we can do.

After taking everything apart, I have discovered that I didn't need to, the part I needed access to (the scanner) actually just pops off. :rolleyes:

What seems to be happening is that at start up, the scanner strip(?) is moved from the left to the right and finally to the left again, but doesn't stop when it reaches the left end, it just keeps going like the printer doesn't 'know' it's reached the edge of the scanner.

I can't seem to find a sensor at the end that tells the printer where the strip is at any one time though. :( Any ideas?

Too late, I've already opened it...
 
I'm picturing OP with a black face, bulging eyes and frizzled hair after getting a huge electric shock, looking like something out of Shoop Da Woop, saying something about discharging his lasers.
 
I'm still alive! :D

Still not fixed it though. I can't work out where this broken sensor is. Guess I'll have to cut my losses. Just spend £50 on a new toner too, haha.
