Hi,
it sounds as if you may have the picture quality set to draft, its worth a check, especially if printing is ok. Does it print colour writing well too or just black, one of the colour inks may have a block or be low, go into printer settings menu and check what print quality its set for.
SOURCE: lines on print. There's are three lines on picture
Have ou gone into your menus. Into troubleshooting, then image quality.
You will want to run both the eliminate light stripes and eliminate smears procedures. that will purge the print head, blow air through the jets and hopefully resolve the problem. I do believe the 8550 has a Jet Substitutin procedure where you can do a workaround and make other jets make up for the light areas.
here are some directions, Will forward more
To clean the printhead using the basic eliminate light stripes procedure:
WARNING: To avoid injury, do not touch the sharp metal strip attached to the clear rubber wiper blade in the Maintenance Kit.
NOTE: Do not try the Advanced Eliminate Light Stripes Cleaning mode without performing two basic cleanings first.
To clean the printhead using the advanced eliminate light stripes procedure:
NOTE: Only perform the advanced light stripe cleaning once. If weak or missing jets still persist, continue with step 8.

Open a program that allows you to insert text into a
document or get on the internet.

If you were to open a program, you would need to type text
into the document. If you were to get
on the internet, you could skip to step 7.3.
After you have typed text into the document, you need to
locate the menu bar, click on file, then point to print.4.
Click on print.5.
When the print dialog box appears, select the printer you
want to use (if it is not already selected) and select the number of copies to
print.6.
Click OK.
7.
If you were to print a page or pages from the internet, follow steps 3, 4, 5, and 6, except you don't have to type text into a document to print.
