Samsung CLX-6200FX series RTC battery replacement (#P41)

Tutorial time! We don’t have a tutorial category yet? Well, it’ll be a project then…

Let’s just skip all the YouTube tutorial BS with two-minute intros on volume 9001 and thanking their sponsors entirely, and get to the point:

You got a Samsung CLX-6200FX series printer (6220 and 6250 – probably also their predecessors 6200, 6210 and 6240) that wants you to set the date and time on every power cycle, and you’re fed up with it? Great, Samsung wasn’t a dick about servicing, so here’s what you need:

* A small Philips or flat head screwdriver

New year, new hardware. Given space (in general, as well as in this specific case) is limited, old hardware has to go. So it’s about time post this 3D printed thingy, since the related hardware is about to be sold.

Now, the Supermicro 815 case, CSE815, SC815 or whatever prefix is en vogue nowadays, is one of those 1U pizza boxes. Shout-out to Supermicro for using webp images on their website already – but sticking to 261 x 222 px resolution for the full-size file.

Anyway, these come in two dozen varieties plus the EOL ones, and all of them have four 3.5″ HDD hotplug caddies in the front and some 1 to 3 card slots in the back, since it is a tiny case at 1U or 44mm height regardless of the 19″ width. […]
