how to remove the printhead on lexmark impact s300 series

Turn off the printer and leave it for at least 10 seconds. So I'm going straight to how I got this problem solved by DOWNGRADING FIRMWARE:įind out and download the firmware version that is closest to the manufacturing date (ours is manufactured in 2017 so I downloaded LW63.SB.P638 which was released in June 2018). I could type in 1000 more words to tell you how I looked around the internet trying to find a solution but I guess you're not here for my story. The new cartridge had worked just fine, until I updated the firmware to the latest version (043) when all of a sudden the printer wouldn't recognise the cartridge and kept showing error message 'replace unsupported cartridge (32.49)'. So, instead of ordering a new toner cartridge from the official website which would cost us A$340.51, we decided to get a bit outdated-looking but still OEM one from eBay for only A$149 (the seller said it was a surplus one he had in stock when he was working from home). Our company purchased a Lexmark MX310dn printer in December 2019 for only A$108.9 and, thanks to the COVID, the original toner cartridge that came with the machine managed to last for 15 months.
