Prior to remanufacturing the cartridge, each product is tested to ensure the drum, usually a dull blue/green colour, is in a good condition. Original drums are very versatile and can in some cases be repeatedly used.
If the original drum has been damaged during the collection and recovery process, a new drum will be fitted which will usually be a shiny light green colour.
Remove the cartridge from the printer and while the printer is still on, remove the power by switching off the printer at the socket. Leave the printer for 10 minutes to allow all power to drain and the error to clear.
In the meantime, find the chip on your cartridge and give it a wipe with some tissue to make sure there is no ink or dust interfering in the communication between the cartridge and the printer.
After 10 minutes, switch your printer back on and re-install the cartridge.
If this did not resolve your problem then unfortunately the cartridge is faulty and should be returned to your store.
If the steps in the answer to the previous question did not solve your problem, re-install all your old, working cartridges. Then replace them with your new cartridges one by one to identify which colour cartridge is causing the error.
Please note that some chips are radio frequency devices and are fitted to the interior of the cartridge and cannot be visually detected.
A small amount of toner powder has fallen onto an internal component of the cartridge. This powder can be removed either by running a printer calibration which will clean the component, or by printing a few normal pages which will naturally clear through the small amount of toner. Once done, the dots should no longer appear on the page while printing.
Many cartridges have a waste tank to collect the paper dust and toner powder during cleaning cycles. Powder from this waste tank can sometimes be shaken loose when you remove your cartridge from the printer.
To remove toner from your hands use cold water with mild household soap. Do not use warm or hot water as this will fuse the toner to your skin.
Printer manufacturers often use the roll out of their printer firmware updates to prevent you from choosing the origin and type of supplies you use in your printer. This has been done is ways such as blocking the use of remanufactured/recycled cartridges entirely, applying a 'cartridge lock' system that locks a cartridge's usage to a printer and introducing a new 'generation' of the same cartridge model to stop older, remanufactured cartridges being re-used.
Most printer manufacturers will prefer you to set your printer to automatically download and install their updates for this very reason. We suggest that you disable the automatic update option to allow you to continue to use remanufactured cartridges and also to recycle your cartridge after it has been used. By allowing your printer to update the firmware automatically you are risking being locked into only using the more expensive and less environmentally friendly original branded cartridges.
So we highly recommend switching off your printer's firmware automatic updates and dismissing future messages asking you to update your printer. These steps are a general guide to how to stop the updates, but please note that they will vary slightly depending on your exact printer model.
