New cartridges do not come with a drum cover. They use a new type of box insert to protect the cartridge. It’s a good idea to have

your customers save these inserts.

The end caps are plastic-welded, and the doctor blade has a left-hand threaded screw, but once past the welds are not that difficult

to do.
