Sharp AL-840 Toner Cartridge - 3,000 Pages (AL840 Toner)

Price:  $59.89
Product Description
Sharp AL-840 Toner Cartridge - 3,000 Pages (AL840 Toner)

This toner cartridge prints 3000 pages with average 5% coverage (Nearly all Printer manufacturers base their ink/toner cartridge yields on 5% page coverage).

This product comes with a 6 month Warranty against any defects (including free replacement). We stand behind our products 100%, as these are not manufactured by Sharp.

Why toner? Why not call it ink? Regular ink dries quickly, which is why cartridges for inkjet printers do not last long. Laser Printers use toner, which is ink in the form of powder. A sealed toner cartridge can be stored for 2+ years prior to usage.

Product Manuals
When do I Replace a Toner Cartridge in the Sharp AL-840 Laser Copier?
There are two signals indicating an exhausted/empty toner cartridge in your Sharp AL-840 Laser Copier. When the toner cartridge is almost empty, the ``TD cartridge replacement required`` indicator will light up, and you must replace the exhausted cartridge soon. If you continue using your Sharp AL-840 with the nearly empty cartridge, the copies will gradually become lighter until all of the remaining toner is consumed. Once the toner cartridge is completely out of toner, the ``TD cartridge replacement required`` indicator will start blinking and all printing operations will be blocked/disabled. Herein, you should replace the exhausted toner cartridge with a new one, before it is completely empty.
How to replace a Toner Cartridge in the Sharp AL-840 Laser Copier
The toner cartridge replacement procedure in your Sharp AL-840 Laser Copier could be defined as a ``user-friendly`` operation, and it won`t take you more than 10 minutes for complete execution. Initially, you must turn off the laser copier and open its front cover by gently pushing on both sides. Now, you must release the old/exhausted toner cartridge by pulling the lock/unlock lever located on its center, then grasp the handle of the cartridge and take it off by pulling slowly towards you. Once the old cartridge is disassembled, you must unpack the new one and then shake it horizontally 5-6 times. After that, you can remove the protective tape and the protective cover, and then hold the new toner cartridge by its handle so the stamped markings are facing upward. Finally, you must slowly push the new toner cartridge into the copier and close the front cover. Now, you can turn on your Sharp AL-840 Laser Copier and test it.

Sharp AL-840 Printer Review


The Sharp AL-840 Digital Laser Copier/Printer can produce eight pages per minute. One of the top features of the Sharp AL-840 is the "scan once, print many" feature as well as a small footprint. Print quality is excellent with no signs of dithering. Colors are bright and clear. The AL-840 comes with dual parallel ports, so two PCs can be connected to the printer at the same time. Additional features include a multicopy function (up to 50 sheets), automatic exposure mode, toner save mode, photo mode, reductions and enlargements from 50 to 200 percent, and automatic power shut-off mode.


The Sharp AL-840 allows you to both print and copy. It will cut down on the cost of running your office. Copies are clear and of outstanding quality. Plus it produces 10 copies per minute which is outstanding. It is great for both large and small offices.

Using the AL-840 is straight forward. Even if you don’t use printers that often, you can figure out how to use all its features without much trouble.

If you are in a hurry to print something out before a meeting, the Sharp AL-840 is the perfect choice since it only takes 35 seconds to produce the first copy. Plus it can be used to enlarge images to 200%.

One outstanding feature is its dual port that allows you to hook it up to two computers at one time. This is perfect for offices with more than a single computer.

Consumables for the AL-840 are affordable and produce outstanding copies. For quality prints and copies you can’t go wrong with the Sharp AL-840.


The only thing missing from the Sharp AL-840 is faxing capabilities. In order to make this an all-in-one machine, Sharp needs to add a fax.
