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

Re: after cleaning cycle ink cartridges are rendered...

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.

Re: after cleaning cycle ink cartridges are rendered...

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.

Re: after cleaning cycle ink cartridges are rendered...

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.

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.

Print head is clogged. Tried cleaning normal. All I got was wasted ink and still clogged print head. It is an epson 4000

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

Where are you located? is it Humid? possibly the chips on the cartriges have something on them (corrosinon, oil from a finger touching the chip, etc) that is interferring with good contact with the wire "feelers" inside the machine. clean the chip with Qtip and alcohol, or fine fiberglasss bristle battery contaact cleaner (hard to find these days)
