dust on print head

I have a piece of something on my magenta nozzle. I have cleaned about 10 times, filled cap, cap cleaned, wiper cleaned. Is there anyway to manually get something from the nozzle?

I need to print a solid print and this gets worse and worse throughout the print, but if I clean during the print I get 2 lines from where the print stays and dries a little bit, and that is worse.

Any ideas?

You might try sending the carriage over to the wiper station and while it is over on that end, fill the Magenta ink cap with cap cleaning fluid. then close door and let carriage return home.
Sometimes the capping fluid without the ink content will be just enough to bust it loose.
Let it sit overnight.
                        Good luck..

we had a similar issue and we got a cleaning sheet from our rep to sit the heads on overnight. it's a a4-sized type of blotting paper that you soak the cleaning liquid onto and then bring the heads out to sit on it overnight. worked a treat!

It is easier to remove the wiper station at the right end to get access to the print head surface.
Use rubber gloves with cleaning fluid. Carefully with your finger and nail peel away dried ink on
the inner edge of the printhead, usually lots of blogs with dried ink builds up there.
Those ink blogs sometimes prevents an air tight seal when it caps and cleans the printheads.
Carefully peel away dried ink that are stuck on the nozzle surface.
After that, clean off with a lint free cloth.

I sometimes experienced that if you have nozzle dropout after a few inches of printing, check obsticles that are touching the printhead surface while the carriage moves and prints.
It can be a loose peeled off warning sticker on the guide plates, or even buildup of ink on the guide plates sticking up just 10th of an inch and therefore touching the nozzle plate.

Latest 2.10 firmware has a strong cleaning feature which is more powerful than the cleaning cycle on the old firmware.

Other things that has an effect are worn out tube rubber rings that sits on the inlet on each print heads but then you would rather get a complete dropout of ink while you print.

You might want to check the heater settings. Too high temperature on the print heater platen and the solvent ink will vaporise before it hits the media and even dry out in the nozzles.
Open the front and back cover, bypass the cover switches to get more air ventilation while printing.


Good luck.
