A mulch is any material you place over garden soil to affect either the soil or the plants growing there. Organic mulches are derived from plant materials that eventually decompose and become part of the soil.
To replace or reinstall the waste toner tank: 1  Open the front cover. 2  Pull on the handles to remove the toner cartridge. 3  Pull the waste toner tank out by the handle. 4  With a dry, lint free cloth, clean the inside wall of the printer and clean the waste toner tank.
The cartridge has a circular window on each side, when the toner level falls below this the printer detects toner empty, what causes this false empty message is the internal paddle in the cart which turns the toner which is still in it, but as it turns it takes the toner with it up out of the beam of the toner low sensor causing the empty cart problem, a full cart weighs approx 860grams, OEM will usually allways stop about 710-730g leaving approx 50-80g of toner still in the cart.
