content: Trying to print out some high quality images and discovered a problem with the magenta. I executed the internal cleaning several times to no avail. I then removed the print head and cleaned with alcohol, but it did not improve. It's a Canon MG5320.What I do not understand is how it prints out a magenta bar on the test, but the other two magenta bars below it (which are supposed to be lighter) do not print out at all. How is it possible for magenta to print out once each test pattern but not the other two bars? Is that a print head issue or something else?Thanks.

content: Or if you want to go really reliable, Colour ribbon. I have a monochrome ribbon printer, and even though it's slow, it will work long past anything that can even interface with it. It has never failed to print for arbitrary reasons, the ink cartridge has no connection to the electronics so YOU can see if it's running low and not have to have a machine refuse to work with one even though it's full of ink. Most of them will work with any computer that has Centronics support (Mine even works on a Commodore 64 WITH bitmaps through a special adapter). The only thing that can really go wrong with them is the heads wearing out, which has not happened to me, and probably will never happen to me so long as I keep to occasional prints.If you need something for speed, then you really have to look elsewhere, but if you are fine with setting 10 documents on to print, loading up the paper feed, and walking away for 30 minutes for great, often cheaper prints, then colour dot matrix impact printers are the best option I can think of for reliability, simplicity, and support. There are even dot matrix impact printers that can go actually pretty fast. Mine doesn't but I do not need to print anything in a time of crush, and can wait 4-5 minutes for a full page print.

content: My services come with a lifetime satisfaction guarantee. However you must supply me with the correct quantity of haggis. Yum!It's a little-known fact of inkjet printers that they have a sort of sponge to rest the heads on, and once it's full, the printer's rubbish.All consumer printers are rubbish in one degree or another. My recent experience of a new (and heavy) HP laser that printed wobbly lines out of the box with its own test pattern sort of confirms this.I ended up with an equally large Brother MFC-9340CDW, which is a LED printer, but also has weirdness. It is able to print straight lines, but the print driver is hilarious, apparently Brother doesn't know most people have more than one monitor.The print dialog opens on the laptop's screen, but with the "main" (external) screen's location. So all I see is the bottom strip of the print dialog on the wrong screen, with no way to fix it. I press alt-space and move the dialog manually.The color copier mode has very bad color accuracy (everything is skewed green), and there seems to be no calibration mode.The printer's OS seems very sluggish on the printer's touch screen. Come on.When printing, it sounds like there are about 15 different competing processes happening inside as the fan revs up and down and up again, and weird internal processes happen. I'd feel a bit happier if the fan turned on, the whole print process happens, then the fan turns off.I gave away (sadly) my 20 year old HP 5L after trying and giving up to make it work with various USB->parallel adapters. So I kept a 2001 W2K machine around for it.Lately all I could find for it were rebuilt toner cartridges. The one I ended up with had a long scratch across the imaging drum and HP wouldn't take it back since it was obviously my fault.

content: I watched that first video, thinking why on earth hasn't he removed the printhead, rather than stuffing bits of kitchen paper in?I've used the syringe method successfully on Cannon printheads using various diameter bits of sleeving to fit the colour and HC black inlets. I used IPA and deionized water. It works a bit better if you keep the bottom immersed in a saucer of water so that you can keep flushing backwards and forwards. If you look at the nozzles under a gecent magnifier you can see if any are still blocked. You just keep going until they are all clear.You can also clean and check the printhead (flexprint) and carriage contacts with IPA at the same time. The contacts get splashed during cleaning anyway, the whole thing is waterproof.

It is a loud, slow, massive beast, but it will be working when every single printer off the line today dies, and it will be working more. If you are looking for SERIOUSLY fast printing where you can go through MASSIVE stacks of paper in a few minutes, regular impact printers can make even the fastest inkjets look like a brain damaged gorilla poking at the paper with a lead stick.They are huge, expensive, can often only do text, but they are FASTFor a good modern printer, I would suggest laser. The toner will kill you (so does ink for inkjets) but they truly have the best print qualities and speeds for a modern printer. We had a monochrome one that could spit out paper after paper after paper in rapid fire succession.Honestly I do still love dot matrix printers. The fact that it's the only printer you can have that will never screw up for stupid reasons (at least in my experience) is awesome. As long as nothing is broken, you hook up the cable to your computer, set a document printing, make sure the paper is loaded, and you will get a print, little to no variables. There may be the issue with some colour bleeds on colour dot matrix impacts, but I'd say if you can get one of acceptable quality and you can stockpile enough ink (nobody uses them so it can be a bit hard to find ink), it will make a perfect backup when your expensive Brother or Epson decides to shit itself and break for no obvious reason.

content: If it has a separate printhead (separate from the print cartridge - usually connected by a thin flexible hose) it may need to be replaced. If the hose is clogged - it may be time for a new printer.Also, not printing color for a long time causes these types of outputs on inkjet. I make it a point to print in color whenever I can.

content: Quote from: xrunner on September 09, 2017, 04:08:14 pmThe reason that cyan and magenta have three bars each in the test pattern is that they actually have three printheads each, for 5, 2, and 1pl droplets. (512 nozzles each for the six magenta and cyan, yellow, photo black, and pigment black.) It looks like there's either a catastrophic clog in the duct to the 2 and 1pl magenta nozzles, or an electronic problem.A replacement printhead (part Qy6-0080) can be had on eBay for about $25, so it may be worth trying that.Quote from: Assafl on September 10, 2017, 08:40:56 amThis model has a separate head, but has no hoses - the cartridges sit in the carriage, directly atop the printhead.As for using them regularly: every inkjet cleans all the nozzles on power-up (or first print after a while), even when just issuing a black and white print job. That said, I've used Canon inkjets since around 2003, and have never had issues with clogging, even after months of disuse. (In stark contrast with the Epson inkjets I used from 1998-2003, which clogged often, and ultimately clogged irreversibly.) The only time I've had to replace a Canon printhead is when I accidentally damaged one.

content: Quote from: drussell on September 09, 2017, 06:43:05 pmEarly inkjets did that, but most now have a rubber-rimmed cap that seals the head shut, and a separate felt-bottomed tray to catch waste ink, which has a specific (and to me amusing) name: the spitoon! Indeed the printers track how much ink is dispensed into the spitoon and disable the printer when full; it's then supposed to be replaced. Service menus usually let you reset the spitoon counter of course.Some printers' head caps have a vacuum hose attached, used for cleaning by actually sucking ink throughwithoutactivating the nozzles, and also for priming the heads after ink changes.

That's the only thing I'm aware of that can really cause a clog in a Canon. That's why they warn when the cartridge is running low (though I really appreciate that the Canons let you override the low-ink warning and keep printing if you choose.)Quote from: Assafl on September 11, 2017, 07:58:24 pmPossibly, but to be honest I'm not entirely sure, I've never dismantled an Epson.The ones that I know have the vacuum pumps are some HP OfficeJet models, the ones that use ink tanks that look kinda like squished marshmallows. They actually have bidirectional pumps that can pump backwards towards the tanks, to dislodge obstructions in the ink paths.Quote from: Assafl on September 11, 2017, 07:58:24 pmIsn't that what most people would simply call their esophagus?

content: Quote from: Brumby on September 12, 2017, 10:28:43 amNo, as long as it is left plugged in, it remembers how long it's been since the last use whether turned on or not, and decides how deep a cleaning to do depending on the interval. If, however, you actually disconnect AC power, it doesn't know how long it's been, and it will default to a deeper cleaning.Leaving it on uses slightly more power just to keep the ports on. I keep mine plugged in but off, simply because the power light is annoyingly bright in my bedroom. Otherwise I'd leave it on.Many Canon inkjets have an intermediate mode, auto power on, which turns the printer "off" but keeps the USB port awake, and turns the machine on automatically. I'm not even sure whether mine has that or not, since I connect via Ethernet, which doesn't have wake-on-LAN.

content: Quote from: Brumby on September 12, 2017, 12:57:39 pmI think that from a technical standpoint, using ink as a cleaning medium is not a bad approach. I don't think anyone would mind wasting ink on cleaning if it didn't cost as much as vintage single malt.I wanna say that some industrial inkjets have separate cleaning solvents, but I'm not at all confident on this point.I think ink formulations are an ongoing vexing problem in any printing context. Every inkjet ink needs to have the right density, viscosity, etc for the printhead and print medium used. Bubble jet (Canon, HP) requires some form of volatile solvent in the ink that boils in a controlled fashion in the nozzle to propel the ink out, while not drying out and clogging. Piezo inkjet (Epson, most industrial inkjets) is far more flexible in terms of ink formulation since it needn't boil the ink, but the print heads are costlier to make, and I believe they're pickier in terms of air bubbles getting in the ink tubing. Presumably when using non-water-soluble inks, like varnishes, it becomes critical to not let ink dry on the head, or you're left with an unclearable clog. (I suspect that's what the problem was in older epsons: the ink, once dried, wasn't able to be dissolved by the ink in the nozzles.)One cool approach in industrial inkjets is using UV-curable lacquers, so the ink really won't dry on its own, and then the printed object is just UV-exposed after the ink is applied.

They were fast, but you did not want to turn them off: the heating and cleaning cycle usedtremendousamounts of ink (on the order of 5% of an ink block!!!). Their print quality was eclipsed by the best color lasers by around 2001, and by the late aughts, cheap color lasers marched them in quality and undercut them substantially in price. I'm actually surprised they lasted as long as they did.FYI, they were invented by tektronix, which called all its color printer products "Phaser". They sold their printer division to Xerox, who continues the Phaser name for its laser printers to this day. They changed the solid ink printers' name to ColorQube for the final few years of the technology's life.

Used 3 of each block per month ( black was free as well, and if you asked for more it was free with the next order, so I always printed as white or other colour text on a black background) even in standby, and half a block per start up cycle in cleaning the ink reservoir and piezo print heads. At $100 per colour per month it was crazy expensive to run, though i did make some black candles from the wax blocks.

If you let them go into standby, then they'd have to reheat and purge when waking up. They really worked best when kept fully on at all times, which only makes sense in high volume environments. (Many Xerox models default to "smart" standby, where it learns the customer's typical usage patterns and then automatically sleeps and wakes for them. But in these, it can be... suboptimal.)

I mean, looking at the earliest inkjets (like the HP ThinkJet) and the ones in the early 90s, who would ever have guessed that inkjet would become the highest-quality printing technology for so many color applications? They've gone from sorry-i-can't-afford-a-laser-so-i-have-to-settle-for-this to actually exceeding laser for photos and graphics, being roughly equivalent for text (except on cheap paper where B&W laser still excels), matching dye-sub for photo prints, but also expanding into areas I never would have predicted, like bulk invoice printing, cash register receipts, and large-format printing like billboards, banners, posters, and blueprints.

For the low print volumes in consumer models, though, it just doesn't make sense to add the machine complexity of that, given that almost nobody actually fills the spittoon.That printer most certainly does consume ink in automatic cleaning -- that it doesn't was such an absurd claim that I looked up theservice manual, and it says that the cleaning function (which wipes the head and then "fills the nozzles with fresh ink") "is automatically performed when the power is switched on, before printing starts, or when printing starts after 24 hours or more". Moreover, it has the "maintenance jet function that ejects ink from all the nozzles of the bubble jet head to ... prevent the nozzles clogging", which "automatically operates when turn  on the printer, before printing starts, every 12 to 30 seconds during printing, or every 1 hour for 24 hours after power on."So yeah, it's using ink for cleaning, just like every inkjet.Quote from: stj on September 13, 2017, 02:31:00 pmMany, many early inkjets used integrated heads in the cartridges, including the HP ThinkJet (the first commercial desktop inkjet, 1984), Canon BJ-10 series, BJ-200 series, etc. Canon and HP now both use integrated heads in their cheapest printers, and permanent or semi-permanent heads in higher-end models.Epson inkjets have never used integrated heads, and like most printers had no chips in the ink tanks until the 2000s.Why did ink cartridges get more and more expensive over the years? Because the printers got cheaper and cheaper. In the end, you're paying a similar amount of money over the life of the printer. The same thing has happened to laser. And as always, very expensive printers with cheap consumables do exist for users with high print volumes.
