HP LaserJet pro 400 m401dn disassembly | How to change LaserJet printer 400 heater | Fuser heater 

The ink tank system appears to be much better than the cartridge system ru-vid.comUgkxciSwynMJ7PnUvvx11rewiu-yFBkZTl53 and a lot cheaper to run. The machine was easy to set up. A small point but I thought they'd be a USB cable included to help with the set up but there was none. I've been using it now for a few weeks and it seems like a good product and superior to my previous printers which were all troublesome HP machines.

Thanks for the simple and very clear video to watch

THANKS ❤

Thanks for the detailed video, very easy to follow.

Thanks you Bro!

why would this model 'print' blank pages without an error message, tonner was half used, tried a new one, no luck, even updated the firmware. Paper comes out hot so I do not hink it's the heater.
