Our old but well maintained 250GT now has a strange printing issue. We had Canon replace the two yellow print heads recently and immediately had an issue where the yellow ink starts to drop out after printing about 20-25 cm of a full bed with heavy yellow coverage.If you stop the print and do a nozzle check it is fine. Somehow the yellow printheads are getting ink starvation while printing?
We did notice that when the machine is idle the ink meniscus level on the popup ink screen fluctuates from 12.1 down to 10.7 and then back up to 12.1.
The Canon techs were in for several days trying to find a fix with no luck.
Ink filter has been changed and meniscus filter changed.
After all 4 colours are purged the yellow are the only heads that have lots of residual ink on the surface. See photo attached.
