Introduction

Due to the large variety of printers available on the market it is impossible to give a specific manual how to dismantle a printer. Therefore, the dismantling steps for inkjet and laser printers indicated below have to be adapted from case to case. No dismantling times and average weights can be indicated.

Remove the toner cartridge.
Cartridges can be refilled and reused! In case they are broken, they need to be disposed of as hazardous waste.

The photoconductive drum is usually located within the cartridge.
Drums from older copy and fax machines may be coated with the toxic substances cadmium-sulfid or selen and should therefore be segregated and supplied to an adequate treatment.
To segregate the drum, remove the axis and store the photoconductive drum separately.
Avoid exposure to the coatings of the Cd- and Se-drums! Selenium-coated drums should be stored without exposure to light (barrel with cover)!

Step 3

Open the plastic casing by unscrewing all screws and removing clips. Clean the casing properly by removing all the foreign materials in the plastic such as labels, rubber mountains etc.
Make sure the plastic parts are completely free of metal pieces.

Step 4

Remove all screws and segregate the PWBs.

Step 5

Remove the fan.

Step 6

Cut off and remove the heating unit, including (brown) heated roller.

Step 7

Separate the remaining materials according to their type and go on with the appropriate data sheet (e.g. aluminium, ferrous metals, plastic, further PWBs, etc.).
Make sure the plastic parts are completely free of metal pieces.
