I am looking for suggestions from the IJM experts as well as the user community on how to clear a stubborn “clog”.
Below is a photo of the nozzle check. I have highlighted (in yellow) the problem spot. Printer is 7880 with Pro inks. I use the printer at least once per week, primarily printing negatives.
These are the things I have checked, cleaned, or done to get rid of this “clog”.
I run a nozzle check using the Epson printer utility every morning and / or afternoon before a print session. If I encounter a nozzle check problem I use the utility to do a cleaning.
I have cleaned the capping station, wiper blade, flush box, and print head per the IJM maintenance video (I do this quarterly).
I remove and agitate the ink carts, in a downward position, once per week.
I have shimmed loose fitting carts to provide a secure fit. And I have visually checked that there is no air in the ink lines; and checked that the carts are primed (and point them downward when agitating to insure prime is not lost).
Using the print tool and QTR in calibration mode I have printed the PK/MK ink flush pattern.
