Hi folks, anyone knows how much developer is in one standart KM toner which weighs about 500 grams. Machines for example would be 4e, 8 series and latest.
Will check later toner data sheets to find if any calculations can be approximated but any input is appreciated.
A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
Blessed are they who can laugh at themselves, for they shall never cease to be amused.
You have got me curious. What are you trying to do? The devtank will discard excess developer through the waste port. I would guess about a teaspoon full per bottle.
About 7 grams - based on simple calculations for C220 toners (because only black is mixed with developer), and it should be close enough to real value.
MSDS will not help you in any way - the percentages described there are very generous (1-10%).

It's a long time ago, but I believe in training the instructor told us it was around 10% developer in the toners

True...percentages are between 2 - 20% (iron + manganese oxid). That means in grams between 10 - 100 grams.
K toner for C220 weights about 50 grams more than color toners so maybe that's the value I will need.

Bear in mind, that color toners lasts for 26k pages, and black lasts for 29k - that's the main source of weight difference (in theory).
This may be or may not be the case. In example TN324K lasts 28k and weight 547 grams and TN324M/C/Y lasts 26k and weights 513 grams, basically 2000 pages more are due 33 grams more in black cartridge. Both contain developer.
TN216 C/M/Y weights 437 grams and TN216K - 524 grams, after some maths it appears toner in K cartridge should be 487 grams and and rest to 524 is developer - 37 grams developer per 524 cartridge.

Maybe experiment with it? Take out a measured amount of toner (say 100 grams) and dispense it into a small plastic cup. Then run a magnet through it repeatedly until you no longer get any iron oxide sticking to it. Figure out the percentage of weight of developer to toner.
A favorite resort of the foreign residents of Yokohama during the summer months is the island of Enoshima. It is about twenty miles away, and is a noted place of pilgrimage for the Japanese, on account of certain shrines that are reputed to have a sacred character. Doctor Bronson arranged that his party should pay a visit to this island, as it was an interesting spot, and they could have a glimpse of Japanese life in the rural districts, and among the fishermen of the coast. "But as we are in for it," he continued, "we must make the best of the situation, and hope to go through in safety. Many a strong ship lies at the bottom of the sea, where she was sent by just such a storm as we are about to pass through, and many another has barely escaped. I was once on a ship in the China seas, when the captain told the passengers that it would be a miracle if we remained half an hour longer afloat. But hardly had he done speaking when the wind fell, the storm abated, and we were safe. The typhoon is to these waters what the hurricane is to the West Indies; it is liable to blow at any time between April and September, and is often fearfully destructive. OPIUM-PIPE. OPIUM-PIPE. "Surely your ladyship knows Dr. Bruce!" Hetty said with a vivid splash of colour on either cheek "A little time ago I understood that Dr. Bruce----" "I require that everywhere a strict investigation shall take place into the conduct of the soldiers with regard to the life and property of the civilian population. "Where were they buried?" They all pressed forward. "Count out. That's the only fair way," shouted the boys in the center. "Now, there's three loaves o' bread for the Sargint," said Harry, laying them down on a newspaper. "There's three for the Corpril; there's three for me; there's three for you." "'T?un't peas, thick 'un," Vennal would break in uproariously, "it's turnips—each of 'em got a root like my fist." At this moment of perplexity, some medicine, that she had obtained from Edith, occurred to her, and, with a feeling of confidence, and almost of extacy, she took a phial from a shelf in a cupboard where she had placed it, and, pouring out the contents in a large spoon, hesitated an instant ere she administered it. "Let me see," said she; "surely it was a large spoonful Edith told me to give—yet all that was in the phial doesn't fill the spoon. Surely I can't be wrong: no—I remember she said a large spoonful, and we didn't talk of any thing else—so I must be right." But Mary still hesitated, till, hearing a sudden noise in the court-yard, which, she conjectured, was her mistress returned, and as the child was getting worse every moment, she leaned back its head, and, forcing open its mouth, compelled the patient, though with difficulty, to swallow its death. The draught was taken; the rigid muscles relaxed, and for a minute the child lay motionless in her lap; but in an instant after, Mary could scarcely suppress a shriek at the horrid sight that met her gaze. The eyes opened, and glared, and seemed as if starting from the head—the fair face and the red lips, were blue, deepening and deepening, till settling in blackness—the limbs contracted—the mouth opened, and displayed a tongue discoloured and swollen—then came a writhing and heaving of the body, and a low, agonized moan: and, as Mary looked almost frantic at this dreadful sight, Edith's words, when she had given her the phial, "that there was enough there to kill," suddenly occurred to her—and then, too, came, with a dreadful distinctness, the remembrance of the true directions which Edith had given. It was nearly noon the next day, when the under-sheriff entered the room to ask if their opinions were yet unanimous. The galleyman still refused. "That for ye, coward," said Tyler, striking him with the flat side of his bared weapon. Oakley aimed another thrust which was again turned aside, and the smith, now flinging down his sword, seized upon his right hand and wrenched the dagger from its grasp. After a short struggle, Oakley fell heavily on the pavement with the blood streaming from his mouth and nostrils. HoME萝拉泷泽第4部资源
