I've had a 4900 for some time and have successfully dealt with many clogs, often using advice from this forum. This time I have not been successful and hope there's a technique I have yet to learn. There is a persistent band of missing nozzles in my cyan nozzle check, not one nozzle in this band delivers ink. A few nozzles have appeared and then disappeared at the edges of the band, but none in the interior. I have tried every method I'm aware of to clear this, all to no or little effect. This includes soaking the parking station with AIS cleaning solution (for weeks), cleanings (including CL3 from the service program), printing between cleanings and even an initial fill. Does anyone have any other techniques to suggest?
Thanks,
Tom
