This is a replacement for the laser shutter arm on HP Laserjet 4000/4050/4100 and possibly the Laserjet 5000. The equivalent HP part number is RB1-8700-000CN. This is a 24 year old printer (1999) so generally only used parts are available. Luckily we have 3d printers.
It is common for this part to break resulting in blank pages. The arm is actuated by a fin on the toner cartridge. The arm presses a lever to open a dust cover on the laser scanning assembly. The laser is blocked when the lever is broken, resulting in the blank pages. My hypothesis is that it breaks if the toner cartridge is installed with too much force.
