CANON IMAGECLASS MF8350CDN BLACK OEM TONER CARTRIDGE

The toner levels for the Canon ImageCLASS MF8350CDN printer can be checked manually at any time the device is not print by pressing the dedicated TONER GUAGE button. Each of the four colors will be displayed next to an OK, LOW, or EMPTY message. Manual checking is not necessary, however, because the printer will alert users ahead of time when a toner cartridge is going to run out soon with a display message.

There are three different messages that may appear on the display screen of the Canon ImageCLASS MF8350CDN that relate to toner cartridges. PREPARE <COLOR> TONER CARTRIDGE is shown when a cartridge is not completely empty, but will need to be changed soon. The purpose of this message is to give users the opportunity to order new cartridges before the current ones run out.

NOTE: On screen, <COLOR> will be replaced by the word BLACK, CYAN, MAGENTA, or YELLOW, thus indicating which cartridge is at an alert level.

A CHECK <COLOR> TONER CARTRIDGE message may appear as well and also does not mean that the cartridge is completely empty. However, when this message appears the cartridge should be replaced due to detection of unstable print quality. This message may appear if a used toner cartridge has been installed.

The REPLACE <COLOR> TONER CARTRIDGE message means that the cartridge or cartridges have finally reached the stage of mandatory replacement. This message means that the cartridge has run completely out of toner or has been damaged somehow beyond use. Black and white printing can continue if a color cartridge reaches this stage, but the black cartridge is mandatory for all types of printing.

Aside from the Canon ImageCLASS MF8350CDN’s alert message system, users may notice white streaks on printed material or areas that seem faded. If this is the case, the cartridge may be too low on toner to print properly even though the system does not detect it. The best solution is to replace the cartridge or cartridges.

Open the front cover of the printer to access the toner cartridges. They will be found in a tray that must be release by pressing the release lever down so a small handle folds out. Pull the tray open by its handle.

Select the correct toner cartridge for replacement based on color and remove it by its handle. Be careful not to touch any of the internal components of the printer. When you open the new toner cartridge, store the old one in the bag it comes in so it can be recycled easily.

With the new cartridge out of its bag, shake it around a few times to loosen toner, then place the cartridge on a flat surface. Pull the sealing tape out of the cartridge by its finger ring and then pull off the protective cover from the bottom of the cartridge while holding it by its handle.

DO NOT let the drum make contact with the edges of the toner tray and carefully install it into place. Push the toner tray back in so that it snaps into place and then close the front cover.
