You can try to 'diaper' the printhead.
Take a clean, nonsheeding clean room wiper (4"x4") double it up, wet it with cleaning solution from a cleaning cartrige.
Release the carriage lock and gently slide the head off of the capping station.
Place the wet cleaning cloth over the cap(s), tucking the loose end down and out of the way.
Gently slide the head back over to the capping station and lock it back into place.
Every 15-20 minutes re-wet the wipe with cleaning solution.
After 1 hour do a strong cleaning.
Then a nozzle check...
Repeat as needed to unclog nozzles.
Be careful not to pour liquid all over the capping station, an eyedropper or syringe will work well to rewet the cleaning cloth.
