I just purchased a Canon TS6420a last week and there are lines in my print. I have done all the cleaning options and nothing works. There are still faint grid (both horizontal and vertical lines). Does anyone know how to fix this? I am printing on regular white paper. Thanks.
Did you try a print head alignment?
If that doesn't work, try different ink cartridges. May be the starter cartridges are a little dry.
Could you also upload a photo of what it's doing?
To make sure, I'm going to take it that it's not a feed problem and it's not breaking apart lines that way. My previous TR4522 did that. I now have a TR7022a. It's similar to yours, but has top feed scanner.
I have tried all the basic cleaning and alignment features on the printer. It does not appear to be a feed problem. It’s looks to me like there’s some overlap in the print and is making those spots darker. Thanks for any thoughts!
Thanks for uploading the photo. I was thinking you were getting faint blank lines breaking the image apart.
You did good troubleshooting steps. I'd try different ink cartridges. May be reinstall the ones you have first, though I'm doubtful on that one.
If the printer still does that with different ink cartridges, I'd pursue as a warranty issue or trade the printer.
