Determining Printhead Wear

Determining Printhead Wear

The most common signs of a worn printhead are fixed vertical streaks that are

always the same size and in the same place on the printout. To determine if

vertical streaks are caused by a worn printhead, follow these methods:

1. Clean the printhead thoroughly with the printhead cleaning pen. Test

again for vertical streaks.

2. Remove the printhead (see page 306) and examine it for contamination

or damage such as scratches, dents, or other marks on the light brown

area containing the heating elements. Clean and install it, then test again

for vertical streaks.

3. Load an alternate roll of media. Test again for vertical streaks.

4. Load an alternate roll of ribbon. Test again for vertical streaks.

If after performing all these tests you still see fixed vertical streaks, you must

replace the printhead.
