I need help on returning a 3880 to printing. My 3880 has printed flawlessly for the year I have had it. This was dedicated to PiezoPro printing. When I had little to no print jobs, I diligently ran nozzle checks and maintenance prints to prevent issues with print head clogging.
To eliminate the need for printing to maintain the print heads, I recently purchased another set of OEM cartridge chips and a Piezoflush cartridge set. This propagated the beginning of my troubles.
With the PiezoPro inkset still installed, I ran a nozzle check and all 8 heads were flawless in creating the manual test pattern. I removed all the inks and replaced them with Piezoflush carts. After purging the ink system, I got a perfect light pink manual test pattern for all 8 heads.
I switched from photo black to matte black. After a few purging cycles, I got a faint pink gray in the matte black position. I did two more black ink changes.
Now, the black nozzle is totally plugged. I am not getting even 1 dash in the test pattern.
For the past several months, I printed with photo black far more than with matte black. Any possibility not using the matte black created my head issue?
Is there any hope for rescuing this printer?
