US 2022/0066382 A1 · SHUTTER FOR IMAGING DEVICE FUSER ASSEMBLY TRIGGERED BY CARTRIDGE

Abstract

An imaging device has a fuser assembly and a removably insertable cartridge with an activation device. The fuser assembly has a fusing nip that heats during use. A shutter moves between a fully opened and fully closed position to allow or block access to the fusing nip. A frame has an opening to allow passage of the activation device of the cartridge. During use, the shutter blocks access to the fusing nip until the activation device of the cartridge passes through the opening of the frame and contacts a corresponding activation surface, whereby the shutter begins opening and travels through a range of movement until reaching the fully opened position when the cartridge is fully inserted into the imaging device. Removal of the cartridge reverses the action of the shutter.

Dependent claims

An imaging device, comprising:

a removably insertable toner cartridge having an activation device;
a fuser assembly having a fusing nip that heats during use to fuse toner from the toner cartridge to media passing through the fusing nip;
and
a frame to support the removal and insertion of the toner cartridge, the frame having an opening to allow passage of the activation device of the toner cartridge, the frame also supporting
a shutter to open or block access to the fusing nip;
and
an activation surface, wherein the shutter blocks access to the fusing nip until the activation device of the cartridge passes through the frame and contacts the activation surface thereby beginning opening of the shutter and allowing opening through a range of movement until fully opened when the cartridge is fully inserted into the frame.
