This is what the film looks like, very thin seamless teflon tube that slips over the ceramic element and housing. The element is a ceramic strip with a resistance compound on it that locks into the diecast frame then the film slips over that. This is the heater: Class dismissed. -----Original Message----- From: computertalkshop-bounce@xxxxxxxxxxxxx [mailto:computertalkshop-bounce@xxxxxxxxxxxxx]On Behalf Of Russ Blakeman Sent: Sunday, December 11, 2005 4:39 PM To: computertalkshop@xxxxxxxxxxxxx Subject: [CTS] Re: Samsung printer The 4000/4100/4200 line as well as the 2100/2200 and others like the 1100 and other smaller units even back to the 5L and 6L line use a ceramic heater (as opposed to a halogen heater bulb) with a spinning teflon film around that (as opposed to a non-stick coated aluminum roller tube) and on some HP had a service note to replace fusers at their cost due to the film guides being produced with a flaw that caused the film to ram hard into one side and eventually shred apart. Other ones from the ignorance of the untrained users will get twisted in half at the middle as they pull stuck paper out incorrectly - they don't use the provided green wheel or the release levers and therefore the paper in between the pressure roller (lower roller) and the combination heater/frame and fuser fil, that replaced the top roller is tight and pulling causes the film to spin on one half while stopped on the other and it twists it apart. I used to buy refurbished fusers, now I get rebuild kits for the fusers at a much reduced cost. I do this on most HP fusers now, film/ceramic and conventional heater bulb/tube roller types. The 4200 and 4250 are another one with a chip, uses an antenna to recieve/talk with the toner. If you pull the toner on the right side of the toner at the edge that heads into the machine first you will see a copper (brass looking) pad with a 3/8" blob of what looks like a melted plastic or epoxy - that epoxy is covering the chip that dies when the toner goes empty so that if refilled it still shows empty. One thing that does cause "remove sealing tape", "toner low" or even a lack of an image on the 42xx machines is a spring wire that stays in the left groove to make contact with the toner's ground that doubles as a guid pin on the left. The design of the 4000 and 4100 for the spring wire is different than the 4200 and consequently the 4200/4250 is prone to the wire getting out of it's place causing ground related mis-behaviors. Your Samsung could have a similar problem but generally Samsungs have been pretty sturdy machines even though not generally the mainstream brand for offices. The way Hp is going they may one day be bottom line and others like lexmark, Brother, Samsung. Okidata, etc be the normal thing in offices. -----Original Message----- From: computertalkshop-bounce@xxxxxxxxxxxxx [mailto:computertalkshop-bounce@xxxxxxxxxxxxx]On Behalf Of Hal Sent: Sunday, December 11, 2005 3:45 PM To: computertalkshop@xxxxxxxxxxxxx Subject: [CTS] Re: Samsung printer Well then, I'm the one who screwed up. I looked at reviews on line and nothing came up about this. They had to have something bigger than this Samsung. It has a three year same-day replacement warranty on it. What do you mean "the films"? It runs nothing but plain paper through it. Or is there something in it I don't know about. They've had a couple of 22xx in there running like that for over two years without a hitch. I also just put in a 24xx. I hope these hod up as well. At EST 04:18 PM 12/11/2005, - Russ Blakeman duly noted: They screwed up getting the 4250N, the fuser is notorious for shredding the films. -----Original Message----- From: computertalkshop-bounce@xxxxxxxxxxxxx [ mailto:computertalkshop-bounce@xxxxxxxxxxxxx]On Behalf Of Hal Sent: Sunday, December 11, 2005 3:12 PM To: computertalkshop@xxxxxxxxxxxxx Subject: [CTS] Re: Samsung printer It has a new cartridge. The company that had this wouldn't have a clue about refills. They use a ton of paper/toner/ink etc. so they having a purchasing company that handles all this for their supplies. This company in turn makes arrangements and takes bids to get the best deal on stuff like this, not just for one client but approximately a bunch. I suppose someone could have slipped a refill to them, but I've never seen anything of this nature happen before. As long as this doesn't affect the printing, it doesn't make that much difference to me. I hardly ever look at it anyway. They were having a little trouble with it jamming, but I think that was because someone was shoving some ragged-edged paper in it. This printer had about 15 people using it, and ran all day long. I replaced it with an HP 4250n. I will say, this sucker really took a beating before I replaced it. At EST 02:11 PM 12/11/2005, - Russ Blakeman duly noted: You think that's big? I have a Laserjet 8150DN I use here, it sits on it's own cart. LOL Anyway those have chips in the toner - is the toner a brand new OEM fresh from the factory, or is it a rebuild or refill? That would make the toner low error show as Samsung is going the way of others and looking at making the big money on consumables - chipping them to make refurb/refill toners a pain in the butt. No way to reset that, that I can tell from any info I have on it. Now if it's a factory fresh new cart then there is a problem. Some are done by electrical contacts, others with the chip transmitting to a small antenna.
