New Epson 9890 "ink cartridge error replace cartridge" on ALL cartridges

[vudutu]

Got a new 9890, set it up worked fine for awhole then started throwing an error "ink cartridge error replace cartridge" on ALL cartridges. Tried reseating them all, the show ok until you put in the last one (could be any of them) then it shows all of them bad. Called service waiting on a tech, anyone with a 9890 seen this?

Hello everyone,

I'm expecting the exactly same problem on myu Epson Stylus Pro 7890.

I've just replaced a bamper and when I restart the printer today all my cartridges are error. The exact error : INK CARTRIDGE ERROR - REPLACE CARTRIDGE
I've already replaced a bamper and had not expected this kind of problem before.

When I insert 8 carts on 9, the screen show me one cart missing and others OK but when I insert the 9th cartridge the error appear for all of them.

Anybody have an idea about this troubleshooting ?

I give this a less than 1% shot at working, but I'll mention it anyway because that really sucks.  Try updating firmware if there's a more recent version.  One of the 9900 firmware updates had a fix for improper ink cartridge error.  Updating my 9900 got me around an ink cartridge error for a single cartridge.  That said, the 9890 and 7890 might have been released after that 9900 firmware update was out already, so those models might have not had the same problem...

I recall a post with the same problem last year.
Turns out the tech that came to repair her 9890 told her that the right side  ink bay had some sort of design or assembly  flaw that if it was loose or shifted slightly from moving the printer  the carts would not register due to improper pin contact with the carts.
I once accidently banged the right side of my 9890 with a swivel chair when the machine was pretty new and had a similar problem with two of carts on the right side not registering. Also make sure the blank carts in the extra slots are in properly.
I think I gave the machine a hard slap on that side by the cart door and brought it back to life !
 do it with the machine turned off and the carts out then re install the carts and see if that clears things up.
