Ricoh IM C530 dumps black toner / Prints come out Black then Blank
Ricoh IM C530 dumps black toner / Prints come out Black then Blank
Having an issue with a IMC 530 replaced K pcdu but after roughly 500 prints went black to start with then please see examples below test page and counter , have tried another drum unit, checked earths, charge bias contacts, swapped ITB anyone have an idea's or seen similar on these devices?
Hey Slim, thanks but its not looking like condensation on this one, have taken the device back to the workshop and get the same results, i have also striped out and cleaned the Black toner pipe, hopper and checked the auger, all of which was ok?

Do you have a spare machine you can swap some parts with to test your problem? Start with K developer.

If all else fails read the Service Manual!
If that fails, meet me at the pub and we will discuss it.
thanks lads, but it has a drum unit, a nasty little device that doesn't look like a real Ricoh, which when the black unit is replaced will work for 500 to 1000 prints fine then starts printing totally black prints before going tot he examples in the first post.
It only happens on K black, on this device you can only get a PCDU and this has been changed twice
It also seems quite out of registration, perhaps the two symptoms are somehow connected by a single problem
I would check the efficiency of the waste toner discharge system, I wouldn't want it to not discharge, so the pcdu becomes hard to turn(out of registration) and by not disposing of the toner it is not able to clean the drum (dark background)...all theoretical obviously
Those samples look like what we used to get in really older Ricoh color machine that had development drive clutches when they would fail. It always had that diagonal pattern on prints. I dont know this machine model at all but can you confirm dev roller is turning and/or the drive for the dev unit side of the pcdu is working correctly. Maybe something is off there and not turning dev unit correctly.
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
