Before you take anything apart
Three things that resolve a surprising share of printer faults.
Power cycle properly
Switch the printer off at the button, unplug it from the wall for sixty seconds, then plug it back in. This clears a genuinely large number of stuck states, including many error codes.
Check what it is connected to
Many offline problems are the printer sitting on a different network from your computer, often a 5 GHz band when the printer only supports 2.4 GHz.
Know when to stop
If a fault involves the power supply, internal electronics or a machine still under warranty, stop and contact the manufacturer. Opening it can cost you the cover.
