I have worked on larger Toshiba mfps like a 7516ac. Are working on production copiers that stretch like 20 feet plus in length all that different to work on? I would imagine there would just be more boards for each section of bridge or finisher units but as far as the main unit, I would think the boards and troubleshooting process would be relatively similar. loaded question I know.
The requirements for service response time, reliability and print quality are significantly higher. There are many different paper feed and finishing options. The machines are also much more robust and built for long runs.
I don't care about who your father is, as long as I'm fishing here, you won't walk on water.
I find production machines easier to work on. More modular and space to work. The trouble shooting is all the same. Do not be intimidated by the size of it. As mentioned the uptime gets much more critical.
Pros:
- Easier to work on
- Parts are generally more accessible inside the machine compared to smaller MFPs
- Service modes usually have more options that will help you diagnose the problems
- If properly maintained, will have many more prints in between calls
Cons:
- Much heavier - if for any reason you need to move it aside, you'll have a hard time
- Customers are much more demanding (with good reason) regarding both quality and response time
- The argument "You see, there's nothing we can do - it's by design" will be much more dificult to sell to the customer.

With production models it is best to keep downtime to a minimum. To achieve that it is advisable to utilize either Field Replacement Modules or Customer Replacement Modules for B/W productions. The main difference is who replaces the modules, you or a trained customer. In either case you do the rebuilds, PMs, usually in shop. For color Production I found it best to have a full set of PCU cleaning stations and an ITB cleaning station to swap our at the customer's and rebuild in shop.
For production sized machines, make sure you keep as close to the PM schedule as possible either with an onsite rebuild or customer replacements. You can run past the yield in most cases, but it's better to keep ahead, especially as the machines run hard and when things go bad: they go bad. My profile pic is from a tear down of an old AF 2075 that had the developer unit contaminate all of the feed bearings and gears. Took a couple hours to replace all of them and get the machine back together, all because the previous tech never kept up with the PM cycles and replacements.
Servicing production machines requires a differnt mindset on the part of your business owner.
Be prepared to stock locally, a dedicated parts cabinet. Customers do not really want to hear about how I can get the part next day by Air freight (which might stretch into two days).
While your experience with the Toshiba 7516ac is valuable, working on 20+ foot production copiers will likely involve additional challenges due to their scale, complexity, and specialized requirements. Adapting to new systems, gaining specific knowledge, and utilizing proper procedures will be crucial for successful service.
1+ I can't stress this enough. On production, you can't let parts go till failure. You must do proper PM's and constantly be on the lookout for what you think the next service call will be and fix it while you're there, before it fails. Also important to stay on top of firmware updates.
Print shop managers don't want to hear you say the feed rollers needed to be replaced, when you were just there two days ago and they haven't run the machine much since then.
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
