Replaceable Internal Component

The page does a poor job of describing what this item is and does.

I just bought a Samsung CLP-300 printer, and read in the manual about the Samsung Waste Toner Collector (CLP-W300A) and what it does.

One of these (the collector) comes with a new CLP-300 series printer.  This is a bottle that fills as you print, with toner that is taken from the toner cartridge cylinders, but not used during the printing process.  Samsung seems to have had a good idea doing it this way rather than having it accumulate in some inaccessible space within the unit.

The Toner Collector also has what appears to be an optical port on the side (most likely to enable the printer to tell when it is full).

The documentation that comes with the printer specifies the Toner Collector needs to be replaced when full, which (it seems) they expect after printing between 1250 and 5000 pages (at 5% saturation for color and B/W print, respectively).  Failure to replace A FULL Waste Toner Collector results in stoppage of printing.

I don't see any reason not to simply dump the toner and clean out the supplied collector when it gets full, except that that could turn out to be a messy job, and it may be simpler to plunk down the 10-15 bucks to just buy a new one.

In summary:  this Waste Toner Collector is an internal part of the Samsung CLP-300 series printer, found just inside the front access panel, and it is easily removed and replaced.

The plastic frame cracked on my original face shield and this is the replacement.  It was easy to remove the old one and snap in the replacement.  The hard part was to remove the fabric sawdust cover and attach it to the replacement shield.  It was rivieted on.  This part would have been much better if it came with a new fabric sawdust cover with it.  As with all replacement parts shipping is almost as expensive than the part, but a lot cheaper than a new helmet costs.

Good Craftsman replacement since you can't buy that anymore.

This item was a very satisfactory replacement for the broken digitizer to
my 3GS.  One should be handy with small tools and fine work to attempt
the repair, however.  You don't have to be a jeweler by trade, but be prepared
to mate and demate the tiniest screws you have ever seen.
I would have given it more stars if it came with clear instructions, but
Youtube has what you need.  However, the youtubes I watched didn't
give me adequate caution how delicate the LCD screen was that you
have to separate.  I busted mine in the process and had to do another
repair of that with a non-OEM substandard replacement.  For a backup
phone/now iPod, it was a cheap way to get it back working again.

Just like the one that we needed to replace--no problems at all

Fits perfectly as a replacement. Easy to find instructions on how to replace via YouTube. The one difficulty in the process - and this is not a critique of the replacement - was removing the wires attached to the original piece, which necessitated pliers and some elbow grease.

Nice replacement for my old one. Fully compatible.

Fairly easy replacement. Anyone whois capable of something like changing a tire can install this. Worked great.
I've used tape at the top to hold the glass and I've used suction cups at the base to hold the glass and they both work fine while replacing this - basically use anything you have available. Watch a video on youtube and you'll understand how to swap this out. bare hands are fine, wearing rubber gloves makes for easy cleanup if this is your first time as you probably will get some of the lubricant on you.
This will save you a bunch of money to do this yourself

This worked perfectly for me. It is an exact replacement for what I had which saved me work and time.

Super easy to replace - perfect fit.  The hardest part is unplugging all the connection wires and getting to the back of the set.  Once you are there, one screw takes off the access panel, two more retaining screws to loosen the existing module.  Pul it out, slip this one in and tighten everything back up.

Perfect!

inexpensive replacement parts for a well used grill

Perfect replacement piece...however, description is not quite clear.  Each package contains two stems.  So if you need to replace
both internals on the faucet handles...just order one.

-Replacement part: the part is exactly the same as the factory version, with the exception that the jack color is black (the factory one is white), otherwise it is the exact same part as the original and a perfect replacement.

-Plastic tools:also included are some cheaply made plastic tools, intended for a single time use to replace the headphone jack.  Included are:
2 small screwdrivers (1 phillips head, 1 flat head).
2 guitar pick shaped plastic tools.
2 lever shaped plastic tools.
1 suction cup with split key ring (not sure what this is for, I believe the suction cup is attached to the back panel of the ipod to aid in its removal).
The quality of the tools is exceptionally bad.  They are only intended to be used once, however, all four plastic tools broke or chipped while trying to pry open the back panel.  One piece of plastic actually broke off and became lodged between the panels of the ipod.  In the end I threw away the included tools and resorted to a pair of plastic tools that came with a previously purchased replacement ipod battery to finish the job.
The screwdrivers are not great but served their purpose, however, they are not magnetized and since the screws in the ipod are extremely small (1 or 2 mm) I would recommend using a magnetized jewelers phillips head screwdriver to handle and avoid loosing the tiny screws.

The replacement of the headphone jack assembly is fairly easy and can be accomplished within 15-20 minutes, just search youtube for a video tutorial on how to do it (just make sure to look for a video that includes swapping out the hold switch).

I read other comments mentioning the lack of the hold switch, this is true for any version of this replacement part as the original hold switch is easily unscrewed and reattached to the new headphone jack assembly.

I provided me the easiest and fastest way to replace components in PCB, no matter the number of pins or connections. Great product!
