Expect to spend 2-3 hours on the job, taking your time. One tip I forgot to show – while you have the carriage assembly out and are cleaning it, be sure to wipe clean the color sensor shutter mirror. It’s on the tiny trap door on the color sensor itself. It is often hazy and obscured over time which can fail the unit. Do not clean the sensor lens or emmiter underneath, it should not need it at all.
I did this video using a ‘kit’ but do not suggest doing so, just get the supplies on your own, it’s nothing special. See this article for details on that.
I am no longer supporting this printer in any way, I have sold my copy.
DO NOT assume there are missing steps! If it’s not mentioned DON’T DO IT! That especially means do not try and relock the release screw for the carriage.
