epson 1400 printer

[valentine rhodes]

I have been printing sublimation with this printer for a long time. Went to use it last saturday, it prints all colours except yellow. Have tried everything you suggest on the forum, with no success. Am about to start pulling my hair out.Can anyone point me in the right direction.Many Thanks Val Rhodes

it sounds like the heads are blocked
but don't try too many head cleans as it only makes it worse after 3 or 4
if that fails try one of the proper cleaners off ebay etc
i bought 1 for £10 and it was terrific highly recommended
sorted my epson heads out a treat

Is it a cis or cartridge. If cis is the yellow supply tube okay i.e. no splits etc. This can often be another cause for no ink pulling through. Do you know if ink is entering the head? If it is a stubborn blockage, try positioning the head over a damp paper towel so that the nozzles sit on it and soften any hardened ink. We have used witch hazel to dampen and soften this in the past.

I have just printed an a4 sheet of paper in yellow. Have done a test print for all colours , colours came out all except yellow.
so the head cant be blocked? or can it.

[Andrew]

Are you saying yellow did come out when you printed just yellow?

[valentine rhodes]

Yes. When i do a nozzle check the yellow wont print.

[Andrew]

Did the nozzle check used to print the yellow? Are the standard prints affected? Do you have alternative options for which test prints you do? Some printers have more intensive options.

If it's printing yellow when you're doing blocks of colour, but not when you're doing the nozzle-check are you sure you're looking closely enough at the paper? When I print nozzle-check patterns on my 1400s, the yellow is almost indiscernible because the lines are so thin. In daylight, and looking really closely, you can see it. Using overhead lights, particularly these useless "economy bulbs", you can't see it at all - but it's there.

One way of checking how good the yellow is would be to print a block of green. Green uses both the cyan and the yellow. If the yellow is patchy, you'll see lines of cyan in the green where the yellow isn't being laid down.

When nozzle check was done before i had the trouble,the yellow used to print.Would it do any harm to get magic bullit and give it a clean.

I was thinking what JSR mentioned about the lines being very feint on the yellow test but didn't won't to ask that one. Often the obvious ones are overlooked.
