printer fuse

[Dave]

Of the three HP printers conected to my computer (1018, 2550 and the photosmart D7360) only the photsmart was smart enough to spot what I was doing. :-)

Is that what the "F" stands for?

Thanks.

[Fred]

There's the catch: I won't know until I've bought one.

Thanks.

I wonder why they can't manufacturer a compartment in the printer to hold the bottles? Could get messy if you knock them over or are they sealed?

My worry would be that the nozzles would still be susceptible to blocking if the printer was not in constant use.

Yes

[geoff]

Where would the profit be in doing that ?

[Fred]

It's a ML2510. On mine you pull the toner cartridge out of the printer and the fuse is on the top left hand corner of the cartridge; there is no need to remove any covers or anything to see it.

I am puzzled how and why they use a fuse to measure how much is left. How does running low blow the fuse? My next question would be why don't they use something that would give the actual level and not need replacing every time but I guess the answer to that is cost.

Where does it say in the user guide or any Samsung documentation that it blows a fuse?

In message , Fred writes

If its like my Epson C1000, then the printer blows the fuse on insertion so that it knows that its a new cartridge

It then sticks its software finger in the air and guestimates how much toner has been used

Things such as GCSE/GCE exam certificates apparently do similar things, at least on photocopiers. Words like COPY appear magically. Something complex like moire patterns? It's amazing the lengths people will go to to produce fakes (for the exam boards to do these interventions)

I've seen a number of traders doing them at computer fairs. Not paid much attention though, as not in the market for one.

I assumed they were for high volume users, and you'd probably go for refilling cartridges otherwise?

[geoff]

In the case of the Epson C1000, it tells the printer that it is a new cartridge

[Fred]

I don't know, I didn't RTFM ;)

I read a non-Samsung web site about refilling and it mentioned some printers would complain that the toner was low even after being refilled because a fuse was used to "sense" how much toner was left. When I bought some toner from ebay, I was sent some fuses which I have now lost!

I can't remember which site that was but I would have foun dit through google originally.

Thinking about it, I doubt Samsung would tell you. After all, it is not in their interests that you do not replace the fuse and refill with cheap toner. Also they would argue that you don't need to know about the electronics inside and how it works as long as it prints the page your computer sends it.

[Man at B&Q]

I know that. Try reading the questions again.

The question "Why would it? " ?

Yes, in response to "Where does it say in the user guide ...".

The manufacturer is only interested in providing an out of ink indication, why would they document the working of it?

Easy, really.
