Epson Sylus C88 prints but there is no ink coming out

You have to go to the properties of the printer and in the maintainance tab do some nozel cleaning and head cleaning.
and check it should be fine
thanks

You should run a nozzle check to verify if the heads are printing all the inks correctly. If the pattern is incomplete you need to run head cleanings.

try replaceing the ink:)

It looks like storm_christ has lost interest in this problem, so we may call it "solved by poster".

If you have carried out 4 to 5 head cleans, waited about 8 hours and done another 3 or head cleans doing nozzle checks after each clean (as recommended by the manual) and there is still no improvement then you will need a third party head cleaning solution such as this one:

Other makes & brands are available just google "inkjet head cleaning solution" Hope this helps.

You have tried almost all the steps. You have to consult Epson Service Support. Don't try more the head can damage.

It probably your head printer is jammed or dirt you have to use head cleaner fluids and inject it from ink head intake

you mean it goes intothe motion of printing and the paper comes out blank ?
you already changed the cartridges and performed print head cleaning. it is having a hardware failure and it needs service. (get a new one instead)(contact the manufacturers customer service and ask for the loyalty program - discounted price)
sad to say but theres no fix-it-yourself for that issue. (you can verify it with the manufacturers tech support)

See my post about about underhead cleaning. If that makes no difference you will need the countermeasure for the split cap tube. The document about loss of ink on CX series machines is also applicable to C88

Sounds like print head issue; have it serviced or u can try this :
