Konica Minolta Bizhub C454E Developer unit leakage
Konica Minolta Bizhub C454E Developer unit leakage
Hi,
My problem started with the printer started to print blank at top of the A4 pages. This was a result of black developer leaking and falling down to the laserunit glass blocking the laser.
I have installed a new black drum and cleaned the laserunit and inside of printer from developer. After that it printed OK for a few hundred prints but now i have the same problem again. Developer everywhere wich have leaked down to the laserunit and blocking the laser.
I think it is developer and not toner because it will stick to a magnetic screwdriver...
I cant understand where the developer is leaking from because there is some developer on the gears but it does not seem to be coming from inside of the gears.
Could you please help me understand what is wrong. If i need a new developer or is the leak because of someting else?
Re: Konica Minolta Bizhub C454E Developer unit leakage
is the upper left duct clogged?
also any dv unit that leaked on me i just replace it and warranty it.
if no warranty its the cost of business we are in.
just to cover all bases id remove the HV and clean the springs/terminals and look for any small cracks on the plastics or the board.
if it is an HV leak you may just fix it by disassembly and cleaning.
either way id replace the dv unit.
We know a thing or two because we've seen a thing or two.
The medication helps though...
Re: Konica Minolta Bizhub C454E Developer unit leakage
Replace dev and drum, clean inside, replace toner filter. Other than that you need tech who knows KM machines. Don't forget to put only OEM toner into machine.

I second what Synthohol said. There is a jig available to clean out the suction duct work . I'm attaching the bulletin you just pull out toner filter , insetert the jig and hook your service vacuum to.
Re: Konica Minolta Bizhub C454E Developer unit leakage
Any consumable that is overlife can make the DV unit fail, for example, if the magenta drum is overlife, it needs replacing, the k dv will keep on failing until the other units that are overlife are replaced
Tip for the day; Treat every problem as your dog would.....If you cant eat it or f*ck it....then p*ss on it & walk away...
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
