If the printer has not have recent use and been sitting unused you can check for pigment clumping or pigment seperation from the ink carrier using a strong torch to check all of the ink lines otherwise the dampers are a final filter before the printhead. Dampers should be replaced every couple...

No question, replace all of them, you've got it apart do it now instead of later.

Double check all head flat ribbon cables are in the correct connectors and are fully and squarely inserted correctly, then perform the adjustments as indicated in the service manual.

Did you follow the procedures in the service manual and also perform the Head Rank ID adjustment when swapping the print head?

I think that in the US most of the Epson authorized service centres will be around the same cost, printheads are expensive, just don't import from Indonesia, a lot of sites that are Indonesian will pop up in a search for a printhead and offer prices that are less than half what you pay in your...

Hannah I'm wondering what your market is, if it's the fine art or art reproduction market then you might consider moving up to a professional epson printer like the new Surecolor SC-P7500 24" printer, inks per ml are much cheaper and are available in 150ml, 350ml and 700ml carts and paper rolls...

Possibly, worth checking the light cyan cart and if you have another (even partially full) swap the carts and try again, also might be a pressure leak on the cart or cart seal around the ink coupling.

Assuming you did an Init Fill after the print head and damper replacement, it may be air in the ink path i'd just do more prints using a light cyan test page then leave over night and try again the next day, lay off the power cleaning too many close together can damage the print head, give it...

Hello, ink dampers will probably have ink clumping (pigment out of suspension) after a long period of no use, replace the dampers and try again. The printhead in these older 7600/9600 printers are really hard to kill, unlike the newer more delicate printheads in the Epson large format models.

Good to hear of your success, the dampers do filter the ink and I have observed fully clogged dampers in an Epson 7880 and pigment separation in the ink lines when the machine is left unused which is equivalent to not using the other black for a long period. Thanks for the helpful update. Cheers.

Oh, I should have added, "before turning the printer on", turning on will start a cleaning process and given the state of the ink it will most likely plug up the print head nozzles.

Worth trying your classic cleaning solution, however you will almost certainly need to also replace the ink dampers and flush all the ink lines as well.

Why not swap the LK and LLK chips?

First, don't power the printer up, after sitting for a long length of time you don't need it to pump clumped ink pigment into the ink dampers and print head which it will do as soon as you turn it on. As Ink Stained Fingers says above, ink pigment will have settled out of suspension from the...

Hi Alex, has the technician corrected your colour cast issue? Brian.
