I'm running windows 8.1 on a Gigabyte laptop with the printer connected wirelessly. I think the problem is mechanical rather than electrical as the printer thinks it's printing ok. I've been refilling cartridges from Inkbank and perhaps I've spilled ink somehow and clogged up the heads, though repeated deep cleaning makes no difference.
When I get a minute I'm going to try more drastic cleaning with some alcohol and cotton buds or similar.
Any other advice would be welcome.
Thank you for your reply,
I see, would like to know if this is also affecting the photocopying function?
If it does then you may proceed with your suggestion on alcohol usage to clean.
If it doesn't, then you may look at your drivers to resolve your issue.
Below is the driver for your re-installation, you may click and begin your download.
Hope it helps,
