Canan s750 head cleaning, burnt head?
Hello,
My Canon s750 has been giving me trouble. It stopped printing black, but my black tank is about 1/2 full. I figured it was a clogged head, and I've tried multiple deep cleaning cycles, soaking in alcohol, and I just tried a cleaning kit from inkjetsaver.com. None of those things helped, and while I was running the last cleaning I began to smell burning from the printer. I pulled out the head and it was very hot, bit there was no smoke. Does anyone have any suggestions on reviving it? Did I just burn out the head on the last cleaning? Thanks. |

IF you were to do many cleanings in a row with a clogged head, I suppose it could get hot and smell, but I wonder if something was not damaged in the alcohol bath. In either case, I dare say it is history. Considering the cost of diagnostics and a new head if that is the problem, my recommendation (if in the U.S. anyway) is call Canon and take advantage of the Loyalty Program. I picked up my iP4000 for just over $130 shipped next day to my door. A new printer, better resolution and a new warranty. That is if you want to stick with Canon any way. |

I'm now thinking that the HP model of replacing the heads with the cartridge is the way to go. I guess you can always buy a refill kit and get a little more life out of those carts? Any advice on a multifunction device? Faxing from home would be nice. |

Having separate tanks and head is the only way to differentiate products without creating logistical nightmare of having to sell hundreds of cartridges. There are two parameters you want to differentiate, and both of them have to be done by having different head: - speed (head with more nozzles) - quality (head with smaller droplets, or with more colors) HP home printers are very limited in parameter range, and this is because of using the same set of cartridges. They don't differ in printing speed too much (are slower than canons especially in color), and are obsolete - they still use 4 pl droplets. I guess when you sell so many pritheads they have to be cheap :-( Even HP knows it's better to have separate head and tanks and separate tanks for each color. But it keeps this superior design for more expansive printers. http://h10010.www1.hp.com/wwpc/us/en...51-411179.html http://h10010.www1.hp.com/wwpc/us/en...f51-33103.html http://h10010.www1.hp.com/wwpc/pscmi...dfs/411179.pdf "Choose HP's most cost-effective color printer for general office use. Save money initially and over time, with a low purchase price and four individual high-capacity replacement ink cartridges that reduce intervention and deliver consistent, outstanding print quality and lowest cost-per-page. Each of the four ink cartridges holds a single color, so when a cartridge runs out, replace only that color, eliminating waste. Four separate, long-lasting printheads are another important element of the economical design-you don't throw away a functional printhead when replacing an empty cartridge." I guess you can always buy a refill kit and get a little more life out of those carts? But it's not as easy as in case of Canon, where you just pop 3-rd party cartridge instead of original, for 1/5 the price. In Hp you either toy with syringes, smear your hands with ink, deal with ink flowing out of the cartrigde, and have a problem with resetting printer settings - as hp printers have protections against refillers built in. Or you buy refilled cartridge, which is unfortunately expansive - costs 1/2 of original cartridge price. I wouldn't count on on HP reliability too much. I used them in the past and had a lot of problems with paper tray - in all models. Like taking multiple sheets at once. Over time paper trays started working worse, at the end it only accepted 1 sheet of paper at once. I guess it's kind of an planned obsolescence on HP's part, as even Lexmark printers have very good and reliable paper handling mechanism. |

Thanks for your great insight into this.
OK, so this leaves me in this position: I have a canon s750 with a burnt out print head. I haven't been able to find a new print head for sale anywhere, but I hear they are expensive. All of the logic behind the separate print head makes sense, and it's the reason I went with Canon in the first place. However, given the extreme cost for fixing it, I'm not sure it's worth it. So this brings up the question: Did my print head fail abnormally? I had been using cheap replacement ink carts, and only print a few pages a month. If I had bought better quality ink, would the head not have failed? I'm stuck here now trying to figure out if I should buy a new printer (I'm intrigued by the multifunction devices), or keep spending money trying to fix the one I have. mpx wrote: "Brian" wrote in message ...

Well, generally you would not need to replace the head. I have several Canon's (one almost 6 years old) and have never had a printhead fail. Yes it can happen just like with any other brand, but with my Canon I know if it does (on the 3 newer units I have) that the printhead is also covered under the warranty. Even with the cost of the Extended warranty from Canon which covered the head for the additional 2 years and using Canon OEM inks, I still save plenty having individual tanks compared to my previous printers with the all-in-one tanks. |

I'm stuck here now trying to figure out if I should buy a new printer (I'm intrigued by the multifunction devices), or keep spending money trying to fix the one I have. Well you can get a new S750 printhead direct from Canon Sales or a local Canon ASF, or even here http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WD1V for about $60. Now while it is VERY likely the problem you experience is due to a failed printhead, you have to keep in mind it may be something else. With the cost of a new Canon iP3000 being just $39 more than the printhead and considering it will provide not only a new head, but also printer with added features (higher resolution, auto-duplexer, dual paper paths, etc) and a fresh warranty, IMHO I would probably opt for the new printer. That is of course unless you know someone that has a printer that uses the same head and confirm your S750 is a bad PH and want to save $39. |

I suppose you simply can't expect reliablility from an inkjet printer
nowadays. They are not build to last. Some time before, when inkjets were more expansive quality seemed to be higher, now it's all shoddy. From my experience quality starts with office-class laser printers that have 500 sheet paper tray and 30+ pages per minute speeds. This kind of hardware is build solidly and works without problems even on high load. I wouldn't count on HP to provide reliable inkjet. All HP inkjets I dealt with had some problems with paper handling mechanism - jamming, pulling multiple sheets or no sheet at all, pulling paper at an angle instead of straight etc. All these problems had been hardly visible at first, then they started getting worse with time. On the other hand they were all printing very well looking text, and their heads rarely clogged even when left for a few weeks of non-use. I wouldn't recommend HP for graphics printing mainly because of too high cost of color ikjet cartridges. |

I have both HP and Cannon. HP45a black cartridges for my 970 are about $26 each, refill spec say 40 ml ink. Cannon BCI-6 Black are $11 each for 13 ml ink. Work it out yourself!!

This kind of hardware is build solidly and works without problems even on high load. While I tend to agree somewhat, I don't think you have to spend a lot of money to get a decent printer. I've owned several printers, both inkjet and laser, over the years, and I've found that durability is not always linked directly to purchase cost, but there does seem to be a negative curve of diminishing returns. I recently had to replace a dead Canon i850 with another printer. I went back to HP since I've had better reliability from their hardware. When shopping, I compared several models and found I preferred the design and build quality of models starting around the $200 price point. Some models below that felt flimsy and cheap, while some more expensive models also felt flimsy. Just a few of the things I look for in a durable model that I expect to last are expandability, solid case and chassis, weight, and logical design. I wouldn't count on HP to provide reliable inkjet. All HP inkjets I dealt with had some problems with paper handling mechanism - jamming, pulling multiple sheets or no sheet at all, pulling paper at an angle instead of straight etc. I've never had paper handling issues with HP, nor any brand really. I've dealt with models that have had 50,000+ sheets put through them, and no signs of paper handling issues. However, I've also maintained the printers by ensuring the rollers don't get excessively dirty. Cleaning the pick-up rollers a few times a year with a damp cloth does wonders. On the other hand they were all printing very well looking text, and their heads rarely clogged even when left for a few weeks of non-use. That has been my experience as well. Their inkjet printers have traditionally been able to endure long periods of in activity without clogging. I had an old HP Deskjet 520 printer sit in a closet for an entire year unused, and when connected to my parents computer, it printed just fine. I wouldn't recommend HP for graphics printing mainly because of too high cost of color ikjet cartridges. After using a Canon i850 printer for 16 months, I don't agree with that statement anymore. I have first-hand experience that shows ink usage is similar to HP and costs are also similar, under typical use. For instance, the Canon ink tanks cost less per colour, but about the same when you buy all three. In another recent post I mentioned this: While the Canon individual ink tanks are cheaper PER COLOUR, they're not cheaper when bought in sets of three, which is required if you intend to print in colour or make photos. For example, here in Canada a large colour cartridge (#97) for my HP 6540 from Staples is $49.96. Yet an equal set of three Canon ink tanks is $53.88 (3x$17.96) for about the same page yields. So when you go to the store and buy a Canon ink tank, you THINK you're saving money because it only costs you about $20 that one time. But the next day when the other colours run out and you buy two more of the ink tanks, you've spent the same amount of money on ink. Canon is using the ILLUSION of lower individual prices to make is seem like you're saving money, when in fact you're not. It's all marketing hype. |
