I’m setting up a refurbished 3880 for Piezo Pro and I believe I’ve followed the manual scrupulously – except that I skipped the step for pre-testing with OEM ink because I asked previously if it were necessary for refurbs, and Jon replied usually not.
I’ve got to the step of printing a nozzle check, and I get a completely blank sheet. I tried both Auto, where it spent a long time cleaning itself, and then finally out came a perfectly blank sheet of Luster paper. I then removed and reinserted all carts. Tried a Manual check and got another blank skeet. I can hear the printer making the noises of printing, but this produces no ziggy patterns at all.
I have not tried a power clean, because if there’s no ink flow I can’t imagine anything would happen except overheating the head?
I took out the carts and looked; on each intake valve there’s a stain showing some ink has entered the lines.
What to do next?
