Required Tools for the Repair
For a clean and successful refill, ensure you have these tools ready:
- Phillips Screwdriver – To remove the side cover screws.
- Small Flat-head Screwdriver – For prying the side clips gently.
- Toner Vacuum – Crucial for removing residual old toner from the hopper.

Step-by-Step Module Replacement & Maintenance
1. Disassembling the Side Covers
The first step is to remove the screws holding the side plastic covers. Carefully pry the clips to separate the toner hopper. This structural design is common among many desktop laser units, similar to the maintenance required when you refill HP CF244A (44A) cartridges.
2. Cleaning the Developer Roller and Doctor Blade
Xerox cartridges are sensitive to toner buildup on the Doctor Blade. Use a soft cloth to clean the Developer Roller. If you notice faint prints or streaks, the blade edge might need a gentle cleaning with isopropyl alcohol. This attention to detail is as important as the steps in our HP 106A/105A refill guide.
3. Refilling the Toner Hopper
Empty any remaining old toner before adding new powder to prevent background shading. Ensure the fill plug is sealed tightly after refilling to avoid leaks inside the printer.
4. Replacing the Reset Chip
The Xerox 106R02778 uses a chip to monitor toner levels. You must replace the chip with a new one for the printer to recognize the cartridge as “Full.” Without a new chip, the printer may continue to display a “Toner Empty” error even after a successful refill.

Professional Advice: Always inspect the supply roller seals during disassembly. If toner has started to leak into the side gears, clean them thoroughly and apply a small amount of plastic-safe grease to ensure smooth rotation.
