T.E.S.T.C.O.P.Y.

Problem in printing plotter.
After cleaning pict 2 in atach.
Print head, ink dampers or pump ?

judging by the photo - the print head is clogged, cleaning did not help completely - clean more

Oldman, do you have any nozzle check picture with pump-cap-wiper problems ?

For example full missing one color in nozzle check is problem,damper,pump,clogged PHead ?

How will I recognize pump problems ?

except for manual testing of the pump - no way. almost any component giving such a failure can be to blame. there are no special diagnostic tools. run a couple of times to clean the print head, then print out 4 large areas filled in (4 colors) per sheet - if there was ink, then the strips are gone - this only means that the ink is not received in time. there may be a fault in the ink pump.

my english - google translate

Oldman,I dont understand your past sentences for testing pump " if there was ink...


Example: epson wf-5620, print head or pump,picture in atach

its a bad google translate.

if the printer prints well first, then the gaps go, then there is a problem with the ink supply to the print head
(google translate)

he meant "if the inks will be on the paper" or something like that

On wf-5620 cleaninig,cleaninig..not good nozzle check black ink on picture above. Print head or pump problem?

in order to understand who is guilty, you must first try to flush the print head - drip the washing liquid from above onto the nozzle for the black cartridge. if the liquid goes bad - flush the head. if the liquid goes well - look at the ink pumping system and the place where the head is parked.
and also - if you do not really understand what to do, look for information on the Internet in your own language - this is better than my explanation curves. Well, remember - there is always a risk in such matters of spoiling the printer - be careful.

I think, the printhead is the cause of your problem. I saw a pump problem very-very rare
