An electronic combination lock of the self-powered type, wherein the electrical energy for operation of the lock is developed within the lock itself, has a solenoid which magnetically seals in the activated position, thus preserving the 'open' condition of the lock until such time as the operator may withdraw the bolt. Significantly, there is no requirement for continued electrical power to hold the solenoid and the latching mechanism in a condition for lock opening.

The charging roller (42) and push plates (44) are spring mounted to the lid (36) of the printer. When the lid is closed, the plates push plungers (11) down to rotate crank arms (23), which open a shutter (7) in electrophotographic cartridge (1). This holds the cartridge in place and provides both a resilient, protective cushion for the cartridge and a pop-up action to the lid.

An electrophotographic printer (11) including a fuser (16, 17) for fusing a toned image onto an envelope (13) passing through a fuser nip (14). Wrinkling and treeing of the envelope (13) is substantially eliminated by removing the pressure on the envelope (13) in the fuser nip (14) for one or more brief intervals during the fusing process. To do this, a solenoid (21) is intermittently driven to remove the force of a spring (18) urging the fuser rolls (16, 17) together.
