HP 4 vertical segment 1 inch wide is darker

My HP 4 is printing with a vertical segment of each page coming out with darker print, as if it is bold print. The segment is a vertical stripe about 3 inches from the left side and 1 inch wide. I can't call it a streak because it is letters that I entered in the text, not just a blob of black ink. The letters in the stripe are a bit fuzzy in addition to being darker.

Take out the toner cartridge and flip it over. Look at the drum under the plastic cover. It should be clean. If there is a stripe in the area mentioned, then it has a failed drum wiper blade.
