o Stick just the copper printhead under the hot water for 3 to 5 seconds.
o Remove the printhead and dry with a tissue.
o Re-insert in the printer and run the printhead cleaning routine.
o Print 2 pages. You should get dilute print for a half page or so and then

good quality printing.

You may add up to 50 percent ammonia for tough clogs.
