Question: I just did a general cleaning on a DI 850, and when I was cleaning the charge corona unit, it popped a code out of the blue. I believe it was a c24 or 26, but I didn’t pay much attention. I thought that if I caused it to reset, then I would be good. I put the machine back together, reset the code, and now my copies look like a mix between bad charge and a bad drum blade—the copies are faint with streaks. Any ideas? Also, how do you get to the tech mode on these? Thanks

Answer: Utility, Details, Stop, 0, 0, Stop, 0, 1. But if it was fine before you cleaned the charge corona, the problem is in the charge corona. Grid backwards, wires not strung properly, etc...

Answer: I just went through this same thing with a di-750. I went there to just give it a general cleaning and ended up with the same symptoms you described. The copies were not that bad before I worked on it. All I did was slide the drum unit out and cleaned some loose toner, etc. It was close to pm so I went back with a new drum, starter, corona wires, and blades. I still did it after pm, and ended up changing the whole drum housing to correct the problem. I was lucky that a friend works for a Minolta dealer and I was able to get that whole assy to swap out. I still do not really know what it was but I suspect that it had something to do with the bias or ground.

Question: Thanks. That will get me in to see the list of codes and their counts. Hopefully someone had reset them. And Frank, did you replace the cl unit, drum, and dv unit with different ones other than the ones you used for the pm, or was it just the cradle?

Answer: To get to the service mode on these, hold the utility key until the screen changes back to the main screen, and then enter 9271 start key. This gets you all the modes at one time, or you can do it one at a time 25, 35 47. Hold down one set then turn machine on in the first way I described until it is better. Then you can go to main screen with utility and clear at the same time

Answer: I used just the cradle and put all the new pm items into the cradle that my friend got from his bone yard.

Answer: Isn’t it 9272?

Question: Thanks for the replies. Went back today and removed everything including the cradle, gave a good cleaning on the bias and corona contacts, and one more once-over. Bingo, everything came back, and now I just need to replace the corona wires. There are still black streaks the more you copy, and there was no detail soft key after utility, but I am going to try the other suggestions. I did order a DI 850 CD manual. I only have one in the field, and it is temperamental and knows how to push my buttons. Thanks again.

Answer: My typo— 9272. I’m getting old

Answer: When you keep holding the meter / utility key down, the screen will go back to user screen. Then look at the top left of the screen where it says enter password. Enter 9272 and press start.

Answer: 9272 is easy to remember if you think of a Xmas tree shape.

Subject: Pitney Bowes dl250Question: How do you enter tech mode on a dl250? It’s the same as a Panasonic fpd250. I am rebuilding a fusing unit, and I need to reset the web counter. Thanks for any help

Answer: This is really hard to find out because although it’s very similar to the Panasonic Version, the Pitney Bowes requires pushing one extra button. It’s a 3 button sequence with the Panny and then one more on the Pitney. If one of the Panny guys can tell us the other 3, and you get it figured out, it’s for your own good to write it down and tape that to the back cover, or inside the back cover, or wherever you know where to find it. I have one that I work on, and that’s what I did

Answer: press User Preset, multi-copy key 3 and Original size ledger/A3 simultaneously. For counters press 7 and start

Answer: Yes those 3 keys sound familiar. One of the other ones near the user preset, ledger keys, is also needed. Hopefully you can get it from here, let us know how it goes.

Question: Thanks, I’m going there today. Hopefully it works out ok.

Subject: Ricoh 2027 reset

Question: I had a bad fuser. I changed it for a good, but I am still getting the same Error SC545. How do I reset the error code? Thanks

Answer: Go into copy sp and clear mf device error sp 7 827

Answer: With that model, just enter SP mode, and then turn the main power switch off and on. You should not have to do anything else to clear the code.

Answer: To reset “A” level codes such as fuser codes, you must perform reset in service mode. SP-5-810

Answer: Yes, 5-810 will reset this error, but straight from the official Ricoh manual, level A codes can be reset by just entering the SP modes, and powering the machine off/on. This is copied right from manual to reset level A codes. Enter SP mode, and then turn the main power switch off and on. Why work harder when you can work smarter?
