Fuser quit working on my laser printer. Removed the fuser and found that the
snap-action bimetallic thermostatic switch for the fuser heating element is open-circuit. I removed it from the fuser and pried it open. Looks brand new. Reassembled it and it now conducts. Then it opened again. Not reliable enough to reinstall due to critical job it does. It rides against the cool roller (not the heated one) and cycles the heating element so as to keep the temperature constant. Markings on front: PW-2N 5214 E150 on rear: PW-2 PWC I've googled but only find these in Eastern Europe or China. Any local suppliers? Replacement part not available from mfr., and replacement fuser assembly is not financially viable; it'll cost as much as I paid for the printer. Thanks. |

You could only indirectly control the fuser temp. if there was a continuous, unvarying , throughput of paper, no stopping and starting.

continuous, unvarying , throughput of paper, no stopping and starting. Is it not just a general output , via air environment, over-temperature cut out ? You're probably right. Now that I look at the fuser in the daylight (not in early hours of the morning) I see that there is what must be a small thermistor resting on the heated roller. *This* is most likely the feedback for the heater circuit. The bimetallic switch must be a over-temp circuit breaker, as you say. And I now see that they both come in contact with the heated roller, not the pinch roller (I thought the red roller was high-temp stuff...) But as for replacement, it's all moot, yes? Or do you have a suggestion re. a work-around? Thanks. |

When my toner ran low, I went to Staples to buy a replacement. 70 dollars! Yeah, just now I looked on Office Depot for toner and it's $85!! And it's a *tiny* cartridge. Will see what's on sale when this toner runs out (c: But what kind of world are we making where the economy pushes us to fill landfills with this stuff? Maybe total recycle (what with RoHS regulation) every time toner runs out? Hmm... Are disposable computers (with removable data cartridge) next? Cars? |

I use www.inkjetsuperstore.com to get toner for about $32 instead of staples
$80 or so, and it works good. I won't buy a laser printer without checking to make sure I can get the toner cheap online somewhere :-) "ehsjr" wrote in message news:EyHHh.20963$tf.18635@trndny06...

If you are in the US or Canada call Premier Parts -
Phone: 800-668-8778 or Fax: 800-668-8037 They are the Samsung dealer. The rating for the thermo-fuse is rated in Celius so it is 150C. I've got quite a few Samsung printers I use for parts so I'll look and see if I have a fuser or the thermister/thermo-fuse. SparkyGuy wrote: Fuser quit working on my laser printer.

Lionel sez:
150c thermal safety fuse. I found most of what you say to be so. I disassembled the "fuse" and it turns out to be a single pair of contacts with a bi-metallic dome (think kid's "cricket" sound toy that you pressed with your thumb) that opens the contacts. When it cools, the contacts are supposed to close again. Mine didn't seem to do that. You're right: there was a buildup of gunk (toner) under the thin teflon (or whatever) strip that separated the thermistor from the roller. Cleaned that up with a blast of canned air. Luckily it wasn't sticky at all. I put the thermal switch back together and installed it All seems to work OK but I won't put the printer into service until I replace the switch. Where would you look for one? Thanks. |

Anybody know how do dial down the toner use on this printer? The white space
on the pages seems to be a bit gray, and the build-up of toner under the thermistor also suggests a slightly "rich mixture". If it was easy to remove the controller board (or just have access to it) I'd probably do a little exploring. But the pan that holds the controller PCB is basically the frame for all the plastic bits to bolt to. It's akin to the heater core in a car. It is suspected that the heater core is the first part placed on the assembly line, and the rest of the car is built around it. Thanks. |

Make sure you're very careful about comparing the replacement part to
the original, & in how you mount it. If the original had yellow/orange film (anti-stick) over it, you'll need to come up with some way of mounting the new thermoswicth so that it doesn't rub on the roller, or it'll scrape off the teflon coating, which will leave streaks on your printouts. It seems that the thermo shut-off is positioned in close proximity to -- but not touching -- the heated roller. It's designed to open when the temperature (within about 1/8 inch of the roller) reaches 150c. The standard method is to bend the mounting bars on the thermoswitch so that it doesn't quite touch the roller. Yeah, that's how it is in this one. Thanks. |

Yeah, that's how it is in this one. Good. That version of the design is easier to fix than the version where the thermal cutout touches the roller, which used a special cutout that had an indentation in it that matched the shape of the roller. (We fixed the older version by bending the tabs on a standard cutout so that they match the roller distance of the newer type.) Thanks. My pleasure. It's nice to know that my hard-earned experience with laser engines isn't just wasting space in my brain. ;^) Not wasted - it is very interesting! I take it that most of the time this type of failure is caused by the build up of crud in there? Is it a fool's errand to try to do preventive maintenance - maybe just as likely to cause a problem as to prevent it? Also, when these printers start "smudging" the non-printed area, is that a sign of impending toner replacement? The prior printer did that for a long while before the printing became light & toner needed replacement. I tried to clean it on a number of occasions, but was not successful in clearing the problem.

(The price has dropped on them since I bought, so they are now $120 not on sale.) Usually these discount printers come with a toner cartridge that is about half full so you will be buying toner pretty soon anyway. Sometimes I believe they sell printers below cost just to create a market for toner. I am sure that is true for ink jets That's exactly what they do. Toner cartridges for my HP laserjet actually wear out long before they run out of toner, Because of the job my this printer does - over printing A5 concert flyers for local entertainment venues - only the centre third of the toner cartridge actually 'applies toner' to the paper, this eventually causes the toner to leak out of the cartridge at either end. Shaking the cart now and then helps. I understand that eventually the scraper blade inside the cart wears, causing vertical lines . It`s kind of annoying to dispose of cartridges that are still more than half full of toner tho. Remanufactured cartridges last longer than genuine HP ones, and are substantially cheaper. I buy toner carts when they are on 3 for 2 offer, Even if they were full price, each cartridge pays for itself many times over, so I`m not complaining. My old Laserjet6L did well over 100,000 prints before it became mechanically too cranky to use. Ron(UK) -- Lune Valley Audio Public Address Systems Hire Sales Maintenance www.lunevalleyaudio.com |

I'd offer to send the OP a thermostat, but it's clearly a
different printer (this one reads the hot roller) I was mistaken -- the thermal cut-out safety switch in the Samsung 4100 I'm trying to fix does monitor thet hot roller (I always though the red-coated one was the hot one... apparently not). and there are no visible markings on it at all (I have not fully disassembled the fuser assembly to see if there are any on the backside of it, but the visible parts have no markings) Well if it looks like this: http://img12.picsplace.to/img.php?file=img12/1/Thermo.jpg (the black end of it with the two mounting/electrical tabs is visible from the exterior of the fuser) please consider it. Thanks, Sparky |

Printing big runs of narrow (210mm) sheets wears out the drum & cleaning blade much faster than usual. When printing lots of A5 sheets, it's better to double-up them to A4 sheets, then guillotine them in half afterwards. You'll get *way* more life out of your cartridges, & it'll also reduce wear on the paper rollers & fuser assembly. That`s very true, but concert flyers already come in A5 size. A simple solution would be to run them through sideways, except the Printer I have wont do it as the paper length is then too short. Ron(UK) |

Is it a fool's errand to try to do preventive maintenance - maybe just as likely to cause a problem as to prevent it? Not if you know what you're doing, but it's enough of a pain to get at the relevant part of the fuser that I've never bothered doing it unless I run into symptoms like the OP's, or am opening up the printer for some other reason, in which case I'll give it a clean up while I'm in there. BTW, a tiny squirt of silicon spray on the woolly, removable wiper on top of the hot roller for every ream of paper you put through the printer will greatly extend the life of the teflon coating on the hot roller, which is hard to obtain, & a pain to replace. It's also good to clean the accumulated gunk of the separation claws (that 'scrape' the paper off the hot roller in its way out), because they're prone to causing paper jams on exit, & can scratch gouges in the teflon hot-roller coating. Also, when these printers start "smudging" the non-printed area, is that a sign of impending toner replacement? It totally depends on the cause, of which there several for that particular symptom. (And there are unrelated problems that cause symptoms that look very similar to the inexperienced.) But yes, the most common cause of dirty backgrounds is a cartridge on its last legs. At a site where they have more than one printer of the same type, the easiest, quickest way to detect a bad cartridge is to swap cartridges with another unit, then do a test print from both. The prior printer did that for a long while before the printing became light & toner needed replacement. I tried to clean it on a number of occasions, but was not successful in clearing the problem. So either I wasn't cleaning the right things, or it wasn't an issue of cleaning. Most likely the latter. If it came good when you put in the new cartridge, you've got the answer to your question. ![]() Lionel, Thanks. Good info, as usual! Ed |

just gotta love the tricks these marketing moguls use to extract our money
from our wallets. they are not concerened with conservation, re-use or longevity. they only seek to enrich themselves by selling us time limited and sales strategic devices that require extreme cost to service or replenish. the initial purchase is a come-on the HP deskjet cartridge, (yes that tiny little ink thing) has probably generated more profit for HP than most all its gear combined. no one in business for profit ever cares about resource depletion until their own kids die from it.. & even then, they figure they will leave THAT problem for their kids to solve.

"if it aint broke,doan figz it" Don't kid yourself. They don't think of it AT ALL. Period. There are two ways to think things like this, unless you're no longer sane, in which case all bets are off: 1. You assume it IS relevent to you, and all that you care about, in which case it nags at you till you eventually do something, ANYTHING, to appease the nagging sense of doubt, in order to make yourself feel more secure. OR 2. You assume your security is ALREADY assured, thus you don't think of doing anything to change what others appear to be whinging about as a perceived threat. Given that the firms doing this ARE amongst the most secure, financially, politically, and socially, their arrogance is the cause. This is not mere ignorance, it is WILLFUL ignorance, the worst and most dangerous kind. It also the kind that is hardest to forgive, and if resources become low enough to make a majority of people start to begrudge this and DO something about the way they choose to spend their money, it will carry on. There are firms that will sell cheap refills, but these aren't the cure, they DEPEND on the problem to exist. Now, as I'm saying my small rant in the presence of electronics engineers, some of which are considering their own business management as well as electronics details, I won't try to tell them solutions they probably know more about themselves, it's enough to point out tht there will be a market for products that don't fleece the buying public at unacceptable expense. I do have one small suggestion, I guess. Innovation is the ONLY way a small firm can get ahead. After all, it;s buying up innovators that makes the big firms get ahead, right? So, if small firms patent their stuff precisely instead of in the aggressive way large firms do to try to stop others, instead of just protecting themselves, this can help, it can prevent a large firm from muying and burying innovation that threatens their own wasteful empires, and it can also prevent them from revising history to try to force their exploitation of your ideas. Patent it under your own name if you invent it. A firm can't claim your idea even if you thought it up on their time! Do they OWN your mind? I think not. At least copyright it by sending yourself signed sealed copies. Do this before it becomes valuable to someone else. There may be all kinds of better ideas to erode the tech society that wastes so heavily, but I'm not inside it enough to think of much more than I have said here. |
