Documents that are scanned have a faded horizontal stripe in the middle of the page about an inch wide. Copies also but more obvious on scans. Prints are fine. I imagine it is a problem with the scanner or optical reading unit...I am wondering if anyone else has ran into this problem.
By horizontal do you mean in the main scan direction or the sub scan direction. And by faded do you mean slightly lighter image or a very light background stripe of some color? One other thing, does it occur off the platen glass or the document feeder?

Does it make any difference when scanning from the glass or from the feeder?

I have attached example. Scanned off of the glass. Change in resolution does not help.
Looks to me like you have a bright spot on the scanner LED lamp assembly. Auto Color Calibration, copier portion, might be able to correct it.
For the best image quality, this is done during installation and should be done periodically by the customer. It is accessed with the "Settings" as follows.
Settings -> Machine Features Settings -> Maintenance -> Auto Color Calibration
At one time Ricoh recommended doing this after every firmware update with the Metis 1, MP Cxx03 series.
I agree, start cleaning the optics and CCD element (carefully). Unfortunately the integrated scanner carriage assy is not as idiot proof to handle compared to the old style scanner design. If the machine is pretty new you can also try using compressed air first.

yes, look, someone probably had the bad idea of adding a lubricant that was too thin to the (almost central) axis of the carriage, and he during the run was sprayed on the mirror, in fact the defect is almost in the center.
you should clean the small mirror hidden near the lens of the carriage, it's a bit difficult to reach, in fact I built myself a tool to effectively clean the optics of that series without swearing, using a piece of plastic, a rag and a couple of pieces of polystyrene to make it soft and adaptable to all inclined surfaces, (the cigarette is there to give the proportions).
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
