Epson 7600 AIR in INK lines

I have an epson 7600 with air in two of the ink lines between the cartridge and the heads. I used a "hidden" maintenance menu to perform an "initial fill" operation to purge the air from the lines. It seems to have worked for one of the lines, but the other line I am still having trouble with.

My questions are: Does anyone know, or can provide (link etc) any information about what else I might be able to do from this hidden mainetance menu? Does anyone have any other amazing solutions for getting air out of ink lines on a printer?

Thanks in advance

SOURCE: Epson Photo RX620: Printing Pink Lines

Hi,

None of these answers are accurate.  I know precisely what your problem is, and you aren't going to like what I have to say.  What you are experiencing will happen eventually to every Epson printer and there is nothing you can do about it other than to buy a new printer.  I have an Epson Stylus Photo 895 ( a 500 dollar printer in its day), which has the same issue.  I am just waiting for my ink cartridges to run out in order to buy a new one.

Endless research on google has turned up that there is no solution to this problem.  The issue you are having is with the Epson print head, which uses piezo technology.  What that means is that unlike HP or Canon printers which are thermal, piezo uses a small piezoelectrical cell to force ink out of the chamber.  It has advantages over thermal in that thermal requires a precise temperature to get ink on the page (what actually happens is that ink is heated, it forms a bubble, and the bubble bursts onto the page, hence the name BubbleJet).  Therefore, the ink has to have fairly precise thermal ink properties making it more expensive to manufacture.  Also, the ink on a BubbleJet (or HP) is wetter when it hits the page, and since the ink is heat resistant or order to properly form the bubble, the printer needs to incorporate a fast drying technology which consumes more energy.  The massive advantage of thermal is that the print head is on the cartridge, not on the printer itself; change your cartridges, get a brand new print head.  It makes cartridges more expensive, but reduces problems such as what you are experiencing.

Piezo on the other hand, always shoot ink through the same print head.  Once the head become damaged over time, the piezoelectric cell is no longer accurately pushing out the ink, and there is nothing you can do about it.  If you are lucky, it is only dried ink in the print head, but I can almost guarantee you that it is not.  Dried ink can be cleaned by repeated head cleanings, even manual ones involving rubbing alcohol.  However, I know that those pink lines are caused by the deterioration of the cell, and cannot be fixed.  If if were only dried ink, you wouldn't be limited to just pink lines on the page, you would see other colours.  If the cell is not doing its job, the lines are always pink (often called magenta when you google this problem).  The solution is to acquire a new print head.  Unfortunately, the cost of replacing an Epson print head is IDENTICAL to the cost of a new Epson printer.

So basically you have no choice, you need to buy a new printer.  Were I you, I would purchase a new thermal inkjet printer so that you get a new print head with every cartridge.  Look around before you buy to find out exactly how much the cartridges will cost, and then you will know which brand to buy.  Although piezo *can* make for a cheaper printer at the outset, Epson simply charged what HP and Canon do for their replacement cartridges because that is what people are used to paying, but you really do get more in a thermal inkjet catridge.

Sorry for the bad news,
DD.

If you are getting that error try this

Check to make sure the locking bracket and screw have been removed from the print head.

Turn off the printer.

Open the lower cover on the front of the printer and remove the bracket and screw holding the print head in place.

Close the printer cover and turn on the printer.

The Pause light, begins flashing and the printer starts charging the ink delivery system.

If a different error then update me, thanks!!

SOURCE: Epson Stylus DX8400 empty ink cartridges but actually new

Sometimes there is a coating on the chips (even original epson ones!) - Old wives tales say dont touch the chips with your fingers - but take the carts out one by one and wipe your finger over the chips (1 finger for one chip - dont reuse the same finger on a different chip)

Reinstall them and that worked for me on a dx4500 with original epson carts in

Air in inkline epson 7600 pro


When u change the printhead on this unit you must be very sure that u unplug it from the wall before u remove the ribbons.t is important that u disconect the line in question from the damper. Take a serenge and start priming the line, make sure ur cartrige is in place, don\'t worry u wil not lose the ink. Prime that thing until u see no more bubbles . Re connect the damper and once that\'s done prime the damper until its full, connect to head Andy should have a working line. If ur serenge is full of ink u can inject it back in the cartrige. Do not do this while printer is on or u will invite more bubbles.....mike

Why doesn't my black ink work in my Epson WorkForce 600 series after replacing the black ink cartridge?


The Epson printer may only use genuine ink cartridges which contain a chip so that you cannot fill the cartridge with ink or use non genuine ink cartridges.

OR

Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer than replace the print head.

I have a Epson Stylus Pro 7600. How can air get in the lines?


The only reason I know is by allowing the cartridge to completely run out of ink. That is why you cannot print in black only when a colour has expired. The printer does not only use the black cartridge it uses a bit from each cartridge to ensure the nozzles stay clean.

You can try an Initial Fill of your ink carts. It is the next level after attempting to clean the heads. However, if this only temporarily fixes your problem, you could have a leak in the supply tubes, or the head could have failed.

Turn the epson off. Hold down the buttons [Paper Feed δ]+[Paper Feed ∇]+[Cut/Eject] and turn on the printer. This will take you into a hidden service menu. Hit the [Paper Feed ∇] button until you get to "Cleaning" then hit the [Select] button to enter that submenu. Hit the [Paper Feed ∇] again until you see "Init Fill", and then hit the [enter] button. The display will say "charging". Just wait until it is done, then turn the printer off and back on.
If you do not have enough ink in the in the carts you will be prompted to replace them. The same goes for the maintenance tank. Make sure you put the ink lever back in the lock position if you change the carts. (It will not give you an error about the ink lever being down, it just won't do anything.)
