„Print Head Cleaning
Clean the Print Head if missing lines or white stripes appear in the nozzle check pattern. This

causes waste ink to be absorbed in the waste ink absorber. Cleaning the Print Head consumes 
ink, so perform Print Head cleaning only when necessary.

Deep cleaning.

There are two ways to align the Print Head, automatic or manual. First, try adjusting the Print 
Head automatically. If the automatic Print Head alignment does not work or if you wish, you can 
adjust the Print Head manually. See “Adjusting the Print Head Manually” on page 165.

fine threads may remain inside the machine and cause problems such as a blocked Print Head 
and poor printing results. Use a soft cloth to avoid scratching the components. 
zNever use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to 
clean the machine; these can damage the machine’s components.
