AL-1661CS OEM DRUM

Your Sharp AL-1661CS is equipped with a built-in drum unit monitoring system, which will warn you, when a new drum unit is needed. The ``Error`` indicator will light up and the following message ``A DRUM CARTRIDGE WILL BE NEEDED SOON`` will appear on your AL-1661CS` display, when the drum unit is close to the end of its lifecycle. When the resource of the drum unit is completely consumed, the error symbol will start blinking and the following message ``REPLACE THE DRUM CARTRIDGE`` will appear on the display. Please note, that all printing operations will be disabled/blocked in this situation. Herein, you must replace the exhausted drum unit with a new one.

The AL-1661CS` drum unit replacement procedure requires the complete disassembly of the toner cartridge. Initially, you must open the multi-bypass tray by slightly pulling it towards you, and then open the side and front covers. After that, you must press the release button of the toner cartridge and slowly pull it out of the Sharp AL-1661CS Digital Laser Copier. Now, you must grab the exhausted/old drum unit by its handle and slowly pull it out. Once the old drum unit is out, you can unpack the new one and remove its protective cover. You must avoid touching or exposing the drum` surface to direct sunlight, because it could result in irreparable damages. In the next step, you must slowly push the new drum unit into the copier and return the toner cartridge to its original place. Finally, you can close the front cover, and after that the side cover by pressing it by the projections near the locking button. Once the new drum unit is installed, the ``Error `` indicator will go out and the ``Ready`` LED will light up.
