So, customer number 1 calls with an issue on his 800. I arrive and the machine displays a 21:10 error, for service station. I clean the encoder, lube the rail and do the basics. Each time you boot, when the carriage goes into the service station, it codes. I assume its the service station, but my tech support says he bets on rail or encoder or something else. Now I have doubt.
Meanwhile, customer number 2 calls with a working 800, and wants service, as it has never been serviced. When I look at it, I see two things. The belt should be changed as it is starting to loose teeth and the whole inside is coated with a light spray of magenta ink. The customer has no idea how long it has been that way. The inside back frame is coated, its all the way up on the board by the control panel and the encoder is covered, but the machine was working. I come back with a belt, change it, clean everything, inspect tubes and find no sign of a leak. I reassemble and the machine codes 21:10. Now I am focused on the encoder. Maybe I did something trying to clean all of that ink off. I replace the encoder strip and now it codes 21:20. I will have to sell a service station for $275, so I don't want to guess.

So you have 2 printers with the same problem? I bet that's never happened before.
How are you cleaning the encoder strip? Have you removed it and examined it closely for damage? They tend to get damaged near the service station but that would usually cause a 86:01. To be certain that the service station isn't causing a motion issue with the carriage, simply remove the service station (but keep it connected) and start the printer.. see what happens. I'd replace the encoder strip before the service station if there's any doubt; always replace the least expensive part first. Encoder strip is $49 from LPS.
Is the service station making an unusual noise when the error occurs? Or not making any noise? Turn the white gear on the side and see if you can exercise it from one end to the other. See if there's any foreign objects in the service station. If there's ink leaking from the seams around the top, it's likely just full and needs to be replaced. If you can pour fluid ink out of it... that's a real good sign it's at the end of its life.
If the service station has a fan, then update the firmware and remove the fan.
The 'magenta' looking overspray is normal for a printer with a lot of use. Simple Green takes it off pretty well.
A service station with exchange is $109 (+shipping) from LPS Computer.
talk to Eddie @ Liberty Parts.. he's good n won't BS YOU
I AGREE both on the encoder AND Simple Green!
Eddie is the one that told me that it is rarely the service station. I have inspected the encoder on the one I didn't change, with reading glasses a flashlight and a white piece of paper. If I had the first call only, I would have replaced the service station by now, Eddie had me doubt that and when I changed the belt on a working one and got the same error, started to wonder what I was missing.

When you move that stuff around, whatever was almost ready to break, breaks. The service station errors aren't related to the encoder. But here's how I handle service station error:
I keep a service station in stock. When I get a 21 error, I simply swap it for $200 (no labor). Then I take the old one back to the shop, clean it up, and get it ready to swap with the next machine.
Most of the time, the problem is just gunked up ink. It takes about an hour or two to clean them out and get them looking new.
BTW - if anyone has a junk one, I'll paypal $20 plus shipping for it.
BTW - the reason I say $200, is because if I go to the customer, and clean out their service station there at their place, it takes about two hours. So I just charge them 2 hours worth of labor for a swap.

Sounds logical. I was on my way to it and got detoured today.

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
