SHARP AR-P350 DRUM

You must open the side cover of your Sharp AR-P350 Laser Printer, and then open the front cover. After that, you must lower the lock lever of the main compartment, and then remove the screw from the front side of the drum cartridge. Now, you must remove the drum cartridge from the main unit by pulling it towards you while pressing its lock release button, and then pull the charger case out of the drum cartridge. Next, you must detach the screen grid from the charger case, and then detach the charger by loosening its screw. Once the charger is detached, you must remove the three screws from the DSD collar and the DSD collar boss, and then remove the used drum and the DSD collar from the drum cartridge. In the next step of the replacement procedure, you must detach the drum separation pawl by removing the six screws, and then remove the three screws that fix the drum cleaning blade to the drum cartridge. At this stage, you must remove the drum cleaning blade from the drum cartridge, and then install the new drum and the drum maintenance kit by following the current procedure in reverse order.
