Cleaning the Printhead

When the ink nozzles of the printhead become clogged, you can restore normal operation by cleaning the printhead.

Types of Printhead Cleaning

There are two methods for printhead cleaning.

THead Cleaning A

Perform when the printing is faint or when dust has collected on the printhead. This cleaning method consumes the least amount of ink. Head Cleaning A requires about 1 minute to complete.

THead Cleaning B

Perform when the printing is blank or when Head Cleaning A does not correct the problem. Head Cleaning B requires about 2 minutes to complete.

Printhead Cleaning Procedure

Follow the procedure below to clean the printhead. The procedure is basically the same for both printhead cleaning methods.

•If one execution of Head Cleaning A does not correct the problem, perform Head Cleaning B.

•If Head Cleaning B does not correct the problem, repeat Head Cleaning B two or three times.

•If three consecutive cleanings with Head Cleaning B do not solve the problem, then the printhead is damaged and should be replaced.
