memory?
When you are using memory management tools

print head?
Clean the head by following the directions in
Chapter 5. If anything is stuck to the print head,
remove it, being careful not to damage the head.
The platen often gets dirty at the same time as the
head, so it is recommended that you clean the
platen after cleaning the head.
