Hi @bluecloud111,

Error code 59.40 for HP Laserjet 4350 means that your printer has a print cartridge motor error.

The actions you can do to fix this error are:

1 Turn the printer off and then on.

2 Replace the print cartridge.

3 Reconnect the print-cartridge-motor
wire-harness on the dc controller PCA
(location J86).

4 Replace the print-cartridge-motor.

5 Replace the dc controller PCA.

Try each action at a time and see if the problem has been resolved. If not proceed to the next step.

I hope that will help. Keep me updated with any progress.

Cheers!
