Message to replace the black cartridge, inserted the new one and the door wouldn't close. Tried to re-seat cartridge, but the left side wouldn't insert fully. Tried to reinsert the old cartridge but it won't seat either (left side issues). Also tried the yellow cartridge below but it wouldn't seat properly either. Help!

If it will not seat on the left hand side then the cartridge locks are broken or the nylon slide that retracts the locks is broken.
See the red arrows. The replacement procedure requires some disassembly of the printer and will require replacement locks.

Where may written instructions or video be found to replace the left side cartridge locks for the HP 3600n laserjet printer? I have the service manual and carefully disassembled the left side down to see three of the four broken locks below a major circuit board but the service manual stops there and I'm afraid to go further without guidance as it looks a little complex with all the springs and other small parts but seems quite repairable with instructions. I simply want to try to properly replace the four locks ( one RC1-7618 and three RC1-6633 ) and associated components.
