I need thinnest sheets, but your "House Brand Sheets" has note: "House Brand sheets are not recommended for chip-cartridge printers." (http://www.icingimages.com/systems.php?link=4).
Please, describe more detailed why "not recommended"? Cause maybe its no matter for my purposes.
My printer - Canon IP4700 with chips.
We have found that the house brand does not absorb the ink as well as other brands. THis can cause build up on the rollers leaving pin feeds. While we do not recommend them, we do have suggestions in the print setup instructions to help to avoid that problem. I hope this is helpful
