Hi all - looking for advice. I work at a school and we have a P9000 that hasn’t gotten much use lately, but we have been doing cleanings and nozzle checks every few weeks. A few days ago we switched from photo black to matte, and now it won’t switch back. It gets to 99% cleaning then says “cleaning error.” Even on startup, it occasionally says “Automatic cleaning error.”
We’ve already wasted a lot of ink along the way as whenever we turn off the machine then back on again it does a cleaning. I squirted some pizeoflush on the cleaning stations and did a flooded paper towel clean under the head.
The nozzle check prints fine so I’m not sure what the deal is.
Just updated the firmware and I get the same error when trying to switch from matte to photo black.
I haven’t run a power clean. Do you think it might help even though the nozzle check is fine??
Could this be a problem with whatever sensor reads the heads?
Is there a way to get it back to photo black through a service menu? (I’ll try to find a copy of the service manual)
Thanks for any help!
