Hi there!
I'm having some kind of similar issu with other users. The model I have is a Canon i-sensys MF3010 laser printer.
When it prints there is one or two vertical white lines across the document or even the half of the page is faint.
It cannot be a low toner level because the printer is almost brand new and it hasn't been used that much!
Also, I can't find any indication in my PC to check the toner level! I've opened "control panel", "devices and printers", "printer preferences" etc but I don't see anthing relevant to the toner level!!
Thank you in advance!!! Merry Christmas!
