Why my printer is blue color missing

The Epson L200 is a factory EcoTank model - it's basically a Epson sanctioned CIS installed at the factory. The name may be different in other countries but for all intents and purposes, I will call it an EcoTank printer since we use this name in the US.

The printer will need to be disassembled to clean the nozzles or you will need to run a cleaning cycle and prey. Outside of that I haven't seen or found a solution that will work with these printers. My solution is only known to work on the black/grey (some with a wetness sensor) cart printers and it's primarily meant to deal with DuraBrite Ultra clogging.

This is complicated further by the fact the Epson CIS looks to be closed loop, unlike the warranty voiding 3rd party units. To add insult to injury, the Epson ink block is a single component (3rd party units are usually separate carts). Because of this, removing the block is likely to introduce air to the system which will spread it to the remaining nozzles and make the problem worse :(.

When I looked at these printers, I had a feeling end users will be screwed when it clogs like every Epson in existence seems to do for no good reason. They also slap you in the face by making the system closed loop, which makes cleaning significantly more difficult. I seen this problem coming from a mile away just by seeing the printers on the shelf.
