The printer doesn’t print nor doesn’t print well after install ciss.
Last Updated: 10/24/2019
(1). The printer doesn’t print anything, or after some printing, it doesn’t print anything.

Reason: Didn’t take off the air vent plugs ( Air vent plugs which are on the top the ink bottle)
Solution: Take the air vent plug off the ink tank. make sure the ink reservoir is on the same level as the ink cartridge, wait for 10 minutes then do a head cleaning and nozzle check.

(2). The printer doesn’t print well after install the ciss, and it printing was good before you installed the ciss.

Reason: There is a few reason can cause that problem.
First is installation time, when you try installing the system, if you let the cartridge holder at the changing position over 30 mins, the print head might dry out. Or have been you out of ink for long time, if you do, it can cause the print head dry out, there is other reason can cause printer dry out.

Solution: After install the system, just do one time head cleaning from printer> maintenance> head cleaning (don’t do it over 2 times, it will be just waste ink and short printer life and nothing will be improved. After that let the printer sit there overnight, and print one nozzle check from printer>maintenance>nozzle check, see if the pattern missing a lot, if it is just missing a little bit, and do another head cleaning and the printing quality will be normal, sometimes it might need in 1-2 days to get back to normal.
Second, there is an air gap in the printer head.

(3). The CISS worked fine for a while, but now one or two color will not clean. I have done the clean print heads cycle of many times and still get broken lines when I print a test page.

Reason: the print head might dry out due to cartridges are empty or the printer head has an air gap which stopped the ink flow.
A. Remove the cartridges from the printer and Prime the CISS cartridge first.
B. Install the cartridges back to the printer.
Push the cartridge down a little harder to make sure the cartridge nozzle connected well with the printhead.
Make sure all the air vent of the ink reservoir are opened. and the ink reservoir on the same level as the cartridge. use a syringe connect to the air vent of the ink reservoir. Push 10 ml air into the tank. Hold for 20 seconds , slowly remove the syringe.(this will push ink to printhead and prime the printhead), Wait for 1 hour, do a head cleaning, then do a nozzle check
