Toshiba E-Studio 850 Toner Cartridge - 6,000 Pages
  OVER 50

Price:  $38.73
Product Description
Toshiba E-Studio 850 Toner Cartridge - 6,000 Pages

This toner cartridge prints 6000 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 Toshiba.

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.

When do I Replace a Toner Cartridge in the TOSHIBA E-STUDIO 850 Laser Printer?
The TOSHIBA E-STUDIO 850 Laser Printer is equipped with a built-in toner level monitoring system, which will warn you, when the toner cartridge runs out of toner. When the toner level becomes too low, you will see the following message ``Install new toner cartridge`` in the upper left corner of your printer`s display. A second message ``Open the toner cover`` will be displayed above the previous. Additionally, the ``Toner cover`` symbol will be blinking. In this situation, you will be able to print a maximum of 2000 sheets, before the toner runs out completely. Once the toner cartridge is completely out of toner, you will see the following message ``Add toner`` and the ``Toner cartridge`` symbol will be blinking. Please note, that all copying functions will be disabled until you replace the toner cartridge. In both of the above situations, you must replace the exhausted toner cartridge with a new one.

When do I Replace a Developer Material in the TOSHIBA E-STUDIO 850 Laser Printer?
There are various signals indicating the need of a Developer material change in your Toshiba E-STUDIO 850 Laser Printer. The most common signals are all including a certain worsening of the printed image`s quality.

How to replace a Developer Material in the TOSHIBA E-STUDIO 850 Laser Printer
The replacement procedure of the developer material in your TOSHIBA E-STUDIO 850 Laser Printer includes the complete disassembly of several other components. You can find the complete procedure below in the exact order of execution.

Initially, you must remove both front upper and front lower covers. You can remove the upper front cover by turning both hinge pins to point at the front side and then pulling them upwards. Once the front upper cover is out, you can take off the lower cover by lifting it up.

The second component on the disassembly list is the front right inner cover. You can take off the front right inner cover by removing its holding screws and then pulling it towards you.

Next for disassembly is the toner cartridge drive unit. You must disconnect the connector and loosen the screw of the bracket. After that, you must take off the bracket, pull down the fixing pin and rotate it by 90 degrees in clockwise direction. Now, you will be able to pull out the toner cartridge unit up to 30-40 degrees from the main printer`s unit and take it off.

The fourth component on the disassembly list is the toner recycle unit. Initially, you must remove 2 screws to take off the left inner cover, and then you must detach the connector. Now, you must remove both side screws, and then you will be able to take off the toner recycle unit by pulling it towards you. Please note, that you must avoid excessive vibrations and toner spillage, while attaching/detaching the toner recycle unit.

The last component disassembly, before the actual developer material replacement, is the Developer unit disassembly. Once the toner recycle unit is out, you must release the developer unit lock by rotating the L-shaped shaft upward. Now, you will be able to take off the developer unit by detaching its connector and pulling it out in direction towards you.

After the complete disassembly of the above five printer components, you can proceed with the developer material replacement. Initially, you must take off the top cover of the developer unit by removing both screws. Now, you can discharge the old/exhausted developer material by tilting the developer unit and rotating the gear on the rear side. After that, you can unpack the new bottle of developer material and pour it in, while rotating the rear side gear. Finally, you must return all printer components to their original places by following the above procedure in reverse order, and then you can test your TOSHIBA E-STUDIO 850 Laser Printer.
