Question about Epson Stylus Pro 4000 InkJet Printer

3 Answers

After cleaning cycle ink cartridges are rendered invalid

I sent my epson pro 4000 in for a warranty exchange becauce i could not get rid of the banding, but that is not my problem. The refurbished printer they sent me worked fine until I would do a cleaning cycle then the yellow cyan and matte black ink cartridges would come up"invalid ink cartridge" and be rendered useless no matter how much ink was left in them. I contacted epson and after lots of discussion they exchanged this printer. Fast forward one month and the new refurbished printer started doing the same thing. I contacted epson again and after a long long letter and much arguing they sent me another brand new printer this time. Just last night I did a cleaning cycle on this new printer and my cyan cartridge came up invalid ink cartridge. I am at a loss. By the way all my drivers, firmware ect is all up to date. I hope you have some answers cause epson sure does not. I thought maybe it was somthing to do with the wiring in my office but I have talked toone other photographer that is having the same problem. Any help would be extremely appreciated. Thanks Murray Olafson

    I havent tried to reset my chips but i am sure stirring the ink will do nothing. I always use epson inks due to fading with other brands. This problem happens wether the ink is cartridges are full or near empty or half full it does not matter. my guess is it is somthing to do with the epson chips.,becauce soon as i replace the cartridge with a new one it will work fine untill i do another cleaning cycle help help help

    The same thing, after 2 cleaning cycles, invalid cartridge message for magenta, a genuine epson cartridge and 1/3 full, replaced cartridge, worked fine. Second time after 2 cleaning cycles, invalid cartridge message for magenta and yellow, both genuine epson cartridges and 3/4 full. have not resolved yet as I don't have spare cartidges or limitless cash.

    Same problem here...I am on the fourth refurbed printer after buying the 'pro' service plan. I just paid around $300 a couple months ago because the yellow cartridge came up 'invalid'.

    Supposedly it was fixed. However, this evening, after running the test pattern, the yellow is 'invalid' again. It is a brand new Epson 220ml cartridge that has an expiration date of 10/2009.

    I think it is time to try Canon printers.

    I have the same problem. The error message says "set ink cartridge"
    but nothing seems to work. It's practically a new cartridge. Where do I get the chip reset tool mentioned by eran in his solution post?

I've had the same problem over the years and somewhere along the way came across this simple fix: when you get the "invalid ink cartridge" message turn the printer off, wait 10 seconds, turn it back on, when the screen switches from "please wait" back to "invalid ink cartridge" tap the pause button. this will somehow reset the printer and you should be good to go.

    well...I tried that Several times with no luck. I did however take the "faulty" brand new cartridge that I bought back and it works like a charm. The customer service lady at Wal-Mart says she has heard of other customers who have had similar problems.hmmmmmmm. Glad to know I didn't have to buy a new printer since I have grown attached to this one. :) I have a Lexmark x5650

It may sound obvious, but you didn't say if whether the ink cartridges you use are Epson cartridges with the right product number. If so, lift the lever and remove these carts and gently rotate them to get the ink stirred and then replace them and run another nozzle or status check. If you're using generic or used cartidges, there are devices that can help you override Epson's cart checker. the printer writes to the chip on the cartridge saying that the cartridge is "used", but You can buy a little "reset" tool which returns the cartridge to a default status.

SOLUTION @ is THE BEST answer, I'm using a BETTER than epson grade of ink, make my own profiles, and pay less. My 4000 is long out of a warranty and this is one trick I almost forgot... save this page for future reference and you will get subaru mileage out of your printer... other printers are less worrisome but epson still has the best output quality in my opinion.

Where is the printer ip address?

You should be able to print the settings from the printer. Press the menu button and go to the reports and print the settings. You can also load the drivers and they will search your network for any available epson printers. I have included a link to the downloads page for documentation and drivers.

My uniform cadet sp750 is not pumping ink from cartridges to dampers what could be the problem

  1. Remove the cartridge/s you have just installed and turn the printer off for 30 seconds. This resets your printer memory.
  2. Check the copper banding on each of the cartridges. This is their contact chip and what communicates with the printer. Give them each a gentle wipe with a cloth to ensure they are clean and dust free.
  3. Reinstall the cartridge to your machine.

I have a damaged cartridge chip sensor in my Epson Pro 4000 printer, I have the field repair guide and new sensor, but can't find any info about replacing this sensor- how can I replace it?

Very old question but not a hard job. Watch this video. :
Or, in the field repair guide you can find the info to turn off the sensors. Google "disable ink sensor epson 4000", thats how I found it, I run all my off. DO NOT DO THIS unless you use the clear refill ink carts that let you see the ink level. NEVER let your printer head run dry.
