I recently noticed that the prints coming out of the Canon have very faint lines across them. I think it has been happening for a while, just that they are not very noticeable. I went back to some prints I had done earlier and saw the same thing.
I have tried pretty much everything:
Made sure I used the correct ICC profile and print settings. I am using Red River paper.
I tried different print programs to make sure it isn’t the software (Lightroom, On1 Photo Raw, Faststone Image Viewer)
I performed several head cleaning and deep cleaning
I performed a couple of print head alignment
I even soaked the print head in a cleaning solution (thinking it might be clogged)
After trying everything I can think of, those lines still appear (see the attached images), and they seem to be present in every different image I printed. I am guessing this is NOT normal. Depending on the image (and the colors), sometimes it is very hard to see them, but it appears they are there.
Question is - is the printhead defective or is it something else?
Solved! Go to Solution.

Hi benlwong,
First, please load plain paper into your PIXMA PRO-100 and print a nozzle check.
Please press and hold the RESUME button until the power light blinks white twice, then let go of the button.
The RESUME button is the middle button on your PIXMA PRO-100.
Please compare your printout with the example below. Make sure there are no lines present. If you like, please take a photo of your nozzle check and post it to your reply of this post.
Next, please print an image using Canon paper using Easy-PhotoPrint Editor. If you do not have this program installed, you may download it for free from the link below:

Hi Patrick,
Thanks for responding. I have done many nozzle checks. Below is one I just ran. I did notice GY has some faint lines, but I have run several cleaning and a couple of deep cleanings with no improvement. As I said in my initial post, I also tried print head alignment as well.
I also printed the same image using Easy-PhotoPrint Editor program as you suggested. I got the same result with faint lines across it (as you can see in the attached image).
