There's a bit of it missing by the electrical contact that connects to the bronze pin at the right side end of the charge rollers assembly.I suspect that rough handling resulted in the left side end of the charge rollers assembly getting dislodged and falling. That would have made the assembly into a gravity-energized lever for snapping the right side arm's retainer.
Here's a view of an intact arm.
The arm is P/N 40X1893. If I can believe Lexmark's service manual illustration, it comes without the spring. I had a written-off T650 to take a good arm from, so I haven't actually seen a new service replacement part to be certain of how it's supplied.Lexmark's service manual has nothing in it about replacing this part. Proceed as follows; it's not difficult to do.
1) Toner Cartridge
2) Paper Tray (Tray 1)
3) Redrive Cap
4) Fuser Cleaning Wand Cover w/Wand
5) Back Door
- Disengage the support strap from its 'inverted T' slot and pull the door off its hinge pins.
6) Lower Rear Cover w/Fuser Access Door -- T650
- Three M3x10mm black washerhead threading screws.
- Open the fuser access door -- two claws.
- Pull the cover away at your left and slide the cover toward your right. A downward-pointing hook will slide off a lip at the rear of the chassis.
- NOTE: The above-mentioned hook makes this an awkward part to get back in place. You have to exactly re-create the cover's attitude as the hook was coming off to get it back on again.
6) Lower Rear Cover w/Fuser Access Door -- T652
- Two M3x10mm washerhead threading screws.
- Two M3x6mm washerhead screws.
- Open the fuser access door -- two claws.
- Tip the cover rearward and lift it off of two hooks at the bottom.
7) Redrive Assembly
- Two M3x10mm washerhead screws.
- Two outward-hooking claws, left and right side, at about the middle.
8) Connection Access Cover
- Open it fully and its hinges can be popped free rearward.
9) Left Side Cover
- Two M3x8mm black washerhead screws in the handgrip wells.
- Two M3x10mm washerhead screws in deep wells in the side of the toner cartridge cavity.
- T650: Tug at the front lip and two upper claws and one lower claw will pop free. The cover's rear hinges come away easily.
- T652: Similar, but there are six claws, and one of them can be quite tenacious. First, pry at the angled upper front lip to free the upper two claws. The troublesome claw is located roughly 3" from the front and 3" from the bottom. You may have to reach in with a long narrow-bladed screwdriver to pry it loose.
10) Right Side Cover
- One M3x10mm washerhead screw at the rear.
- Two M3x8mm black washerhead screws in the handgrip wells.
- Two M3x10mm washerhead screws in shallow wells in the side of the toner cartridge cavity.
- T650: Tug at the front lip and two upper claws and one lower claw will pop free.
- T652: Similar, but there are six claws arrayed as on the left side cover.
11) Top Cover
- One M4x10mm pan head threading screw at the right rear.
- Four M3x10mm washerhead threading screws.
- The front edge has to be forced up past the rear edge of the upper front door. NOTE: It's a bit difficult to get this cover levered back into place at the front, but it is doable without damaging anything.
12) One Ty-Wrap at Frontward Red Wire
13) Black Charge Wire Spade Terminal at HVPS (High Voltage Power Supply)
- Disconnect the terminal and extract the wire from its restraint at the side.
14) Right Side Charge Rollers Pressure Spring
- Raise the upper front door.
- Unhook the spring at its front end.
15) Hinge/Arm-Link Pin
- One tiny e-clip.
16) Steel Cross-Member at Rear of Chassis (T652 -- not present on T650)
- Three M3x10mm washerhead threading screws.
17) Right Side Charge Rollers Arm
- NOTE: This part is removed by unfastening the upper portion of the right side vertical frame member, and prying the frame member aside until the arm can be slid off its pivot pin. (This is by no means a factory-approved procedure, but it does work and nothing breaks, even though an outrageous amount of prying is needed.)
- Five M4x10mm bright pan head threading screws. They're prominent and easily spotted.
- Pry aside the frame member.
- Raise the arm and slide it off its pivot pin.
- Transfer the spring to the new part.
