Hello,

I have a problem with a MIS cartridge that I am using with the UT 
inkset. The ink monitor tells me that the inks are 80% full, but a 
nozzle check shows no lines in the yellow position. I replaced the 
cardritge with an Epson original and noticed that the MIS cartridge is 
very light. All colors are fine with the Epson cartridge. I think that 
in the MIS cartridge the yellow-position is empty and the others are 
running low!

I refilled the cardridge a couple of weeks ago. Prior to that, when it 
was in the printer, the ink monitor was showing about 10%-20% ink for 
all colors, but I started to get bad nozzle checks that were getting 
worse (fast) with cleaning.  Originally I thought that it was clocking. 
However, before refilling I extracted the remaining ink from the 
cartridge. There was very little of it. So I thought that it was just 
that the sensors where not reliable and that my bad nozzle checks were 
due to insufficent ink in the cartridge.

However, now the cartridge seems to be empty again! Only about two weeks 
after reffiling the! During this time I think I have printed the 
equivalent of perhaps  four 13x19in. pages only.

Can someone tell me if the capacity of these cartridges is this low? Or 
perhaps the one I have is defective and should be replaced? I refilled 
it once after filling it the first time.

Thanks in advance!
