Epson r340 Printhead removal
I am getting streaking in my black and I have cleaned the printhead
half a dozen times with no improvement. I the past with my Canon printer I would take out the carts and lift a lever that would allow me to remove the printhead where I could soak it in ammonia and water and return it to the printer and it would work great. This Epson looks like there is more to it than that. Can the print head be safely removed for soaking? |

Epson r340 Printhead removal
don't remove the printhead. Look through the posts for Arthur Entlich and
email him with a request for his Epson printhead cleaning manual. No charge, no spam, just an excellent manual on techniques Epson doesn't tell you about. "Mark" wrote in message oups.com...

Epson r340 Printhead removal
I would normally say drop Art (Arthur Entlich) an Email requesting is
free cleaning instruction's, he's not been round for a while, don't know where he's got to..? His email is e-printerhelp(@)mvps(.)org remove the brackets leaving no spaces. The print head on a Epson are not like the Canon's... the heads are usually part of the whole assembly along with the ribbon cable. May be an easier way is to release the head from the locking position, by switching it on and pulling the power plug out (or switching it off) during the shuffle cleaning period... ....then with a piece of paper towel fold a thin strip add some cleaning fluid lay it on the bottom and gently manually move the head over it a couple of times, to let the head sit on it overnight may be better. Unlike the Canon head the ribbon cable goes to a connector board and then another short cable to the nozzles.... the cables are not removable except from the printer's PCB end, dipping in too much liquid will damage this connector board in the head assembly. Another way, a little more expensive is to get a cleaning cartridge, do a couple of flushes and leave it in situ overnight then the next day another flush... and with new ink tanks give a couple of flushes and then try, if this don't work then I doubt anything else will.

Epson r340 Printhead removal
I wonder...
The carts look like they "plug" into the printer head. Could I place a towel under the head, then using a hypodermic syringe w/o the needle filled with cleaning solution, remove the cart and push the end on the syringe tight against the opening on the print head and force the cleaning solution under pressure through the print head, catching the excess on a paper towel? Has anyone tried this? |

Has anyone tried this? If you mean put a syringe on the nozzles that pierce the cartridge, not a good idea. First they are fragile, secondly it's difficult to get a good seal, thirdly is the risk of too much pressure. I've also found once you remove a cartridge it will probably leak if you refit, ink all round the printer innards. You could try getting some of the old cycle valve rubber tubing, fits nicely over the spike. Some clear auto screen washer tube. Join a short piece of rubber tube to the latter. If ingenious make a blood transfusion type flow indicator. So you can see the drops. Now set up a simple syphon, with about 1 - 2 feet of head, virtually no pressure, put paper towel under head to collect cleaning fluid, watch the drops flow, marvel at your ingenuity, and reflect on how the drops are cleaning the head. Only residual problem is that if the block is solid particles of dried ink, and with many of the refill inks you don't know the composition, they don't dissolve no how. I suspect they may contain a few percent of something resinous, and once they dry in the head it's knackered. Pity with Epson, you can't remove the head, don't be tempted to try it, otherwise you could use one of the under 20 quid ultrasonic cleaners. The Epson workshop manuals, covering assembly and disassembly, waveforms, voltages etc, would put you off fiddling without the appropriate facilities and supporting parts store "Well it needed replacing anyway", mode of servicing. I suspect a steep learning curve for printer maintenance, and of course the public has no stockroom full of spares. Ever tried to buy Epson spares, or even a service manual, they do exist? |

Davy Arthur's manual has a recipe for making cleaning carts - if you have some old empty ones it is much cheaper than buying them. |

Epson r340 Printhead removal
I used Davy's idea of unplugging during startup to free up the printer head
assembly. I took a paper towel and soaked it in 50/50 ammonia and water and layed it down and moves the printhead manually across it several times, them left it sit on the towel for 15 minutes. I just printed as pretty a photo as this thing is capable of, so thanks all. BTW, I'm using a CIS for this and I wonder if I'm going to have trouble as a result. |

Epson r340 Printhead removal
Hi Davy,
I'm around but very busy. I was away for a week and have been catching up with the many requests I received while I was away. Now, I have a number of other endeavors taking up time. I'm running on a few hours of sleep here and there. I am trying to reply to people within 24-48 hours until I get thing more settled.
