well it sounds like clogged heads, or Nozzle or an elignment problem
Before anything just run a few runs at head cleaning on nozzle and on head checks first and then run a test print to see if all colours are printing out on test paper first.
I would not like to take through the process of stripping the printer gear assembly down just so the heads can be cleaned but sometimes it can be simply that the cheap cartridges are clogged and will need replacing,
There are built in cleaning methods within most printers one will be a nozzle check and the other is head cleaning under the maintenance section in the properties of the printer,
Sometimes I have had to use up some cartridges just to blast out the dried ink
This is costly but sometimes this has to be done.
another method is as a last resort method please let me reiterate LAST RESORT is injecting or tipping in a few drips of methylated spirits 500ml bottle usually purple a little into the cartidges through the bottom hole which is ok because you have already puntured it to let the ink out when you popped them in there again this is last resort please ware plastic gloves put a cloth out hold cartridge upside down let the little bit soak into the sponge inside the cartridge
this is abit trial and error you need plenty paper and choose a print design thats is going to use or need alot of colours set the printer to max colour like for photo and print a few then run a test to see if you are getting all the colours coming through on the test section if you are problem sorted if you are not nozzle check again head clean again, but do not put anymore meths into cartridge just re run nozzle checks and head checks this will propably run the cartridge out but you will have a back up ready, if after all this you are still not getting getting a good quality picture unfortunatly the heads gone and it will have to be replaced.
hope this helps
Check the ink wells are installed in correct order. Next, do a nozzle check (same place as the cleaning). This will have you print a pattern and ask you if it looks normal. If yes, you are good to go. If not, you may need to align the print heads. This can also be done in the same place as the print cleaning and nozzle check. Hopefully that will take care of the problem. Next step is print head replacment.
Hi, first the approximate ink shown by the software
in computer is not always correct.cartidge may have very low ink level. second reason may be nozzle of cartridge may be
blocked due to dust. so first try to clean the cartridge nozzle with
moist cotton or with tissue paper. if the problem continue replace the cartridge
with new one.
Nozzle check perfect? No ink drop outside lines? Cyan lines is random position. Print blank pages. It is still appear cyan lines? If yes, it caused by waste ink at bottom plate. Print blank pages more, it will clean itself.
Your inkjet nozzles may be clogged with old dried ink. Try removing your color cartridge and looking at the area on your print carraige where the inkjet cartridge mates up with the carriage. Use a Q-tip and warm distilled water to gently swab this area until all the old ink is dissolved and it wipes clean. You may need several Q-tips for this. Allow to air dry and reintall your print cartidge. Your printer should go into an automatic cleaning cycle. You may also need to gently clean the area on the cartidge itself using the Q-tip method. Good luck.
Hi, I have question?
The ink that yuo are change are original epson cartidge ink?If yes , try to head cleaning twice and then nozzle check ,then the result of test print are soild in color are good , the unclean head having plenty spaces within the color in test print.
I bet you are using non genuine ink, the MP780 will not put up with that ink, you will need a new printhead and maybe a purge unit.
Take the machine to your ink supplier and get him to fix it as he supplied the ink
