I'm attaching the service mode prints I get. The black on my Ricoh MPC2500 is AWFUL - printing splotchy.
Is this a bad black drum unit? That is my best guess, but I'm looking for other opinions.
Thanks!
Sir,good day!can you give me a exact no. of prints of your machine so that I can answer you briefly because every pm parts theres a life span maybe its over already.have a nice day,im waiting for your reply thanks
it looks like laser or charge roller for the black drum. there is a long stick attached inside the cover, have you done cleaning the laser mirror by this stick? if you do and still the same prob, check on the charge roller for the black drum, maybe it is full of toner causing this bad copy.
hope this will help. good luck buddy!
Looks like a laser shutter to me. I've seen the charge rollers leave debris on lines behind when they start to fail. You're just not getting the exposure from the laser to write the image properly.
Firmware is your solution. It's on the TSC/TESSA website, or can be done by a certified technician.

I'd be lookin at either the laser shutter or the charge roller on the drum. But it's always a good idea to have the latest system and engine firmware. ps how did you print off the first test pattern, not the acc the 1st one?
Grant me the serenity to accept the things I cannot change.
So, I've gotten a new Black PCU and updated the engine and printer firmware. Now, things are looking much better, BUT black text is coming out fuzzy. I've attached a scan of two prints, one from a PDF and the other from a native InDesign file (design software).
If you're going to update firmware, its best to do it all - sometimes there are incompatibilities between versions.
Your fuzzy black line is likely caused by toner scattering from the thickness of the layer created when the pdf file prints process black (C+M+Y+K instead of just K) and is typical of what I see on this machine.
I have a feeling your ID sensors are dirty and its got the process control hosed. Clean everything up (including the scanner), and run an ACC - that will force Line Position and ProCon. Then repeat your test images - one process control cycle may not fully correct the problem, but you should see an improvement.
I'd have to agree with Shadow. PDFs do tend to fuzz out heavy black line when created as composite black, even when color registration is perfect.
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I was going to say the same thing about Firmware. I've been told ALWAYS Do them All. But Read the PDFs. Many of them need all of them to work right.
Portion I bolded above is what I thought too, but was uneasy in saying. Hate to be wrong. I did learn something about things in your last paragraph.

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
