Question: I’m working on a Sharp sf-2025 for a local non-profit. It has a blinking Developer indicator, and I’m getting blank copies. Is there a simulation mode I can use to reset it and determine if all it needs is a developer change? I’m not getting any image on the drum when I do a panic stop and check. I do have a service manual to reference. Looking for some help getting to the heart of the problem. Thanks Much!!!

Answer: The heart of the problem is that it reached PM time, and the PM counters were reset rather than doing the PM. It will have to have a full PM, including Drum and DV, and the steps need to be followed to the T from the service manual...anything else will lead to constant troubles, causing you to look like a noob. Good luck.

Answer: That copier is unforgiving of shortcuts.

Answer: The reason the developer light is blinking is because the copies are blank—fix that problem and everything should be fine. The developer light blinks when the drum patch sensor gets a reading that is out of range (like when there is NO patch!) Don’t reset the PM counters unless you do a PM– that’s a definite on this model.

Question: New drum, developer, charge grid and transfer wires—anything else? Thanks for the help!

Answer: A blinking developer lamp actually indicates an F-2 error, whereas a steady lit lamp indicates that the developer counter reached 80K. Sometimes you can get away with fixing the blinking condition by cleaning the drum unit, but it is most likely a symptom of other issues related to the drum and/or developer. It would still be most prudent to plan on replacing all of these items as others have suggested. But for future reference, you should know that the blinking lamp is not a simple PM indicator.

Answer: Although new up and lower oil rollers is a good idea, you are not doing the non-profit a favor by fixing this. It is too old and too picky of a machine for a guy to learn now. Find and trade in a good used machine and donate it to them if you really have them in your heart. If it is just another paying job, you will eat a lot on this. It was a great machine for guys who knew it really well when it was new, but it is not good now. LOW VOLUME WILL NOT MAKE THIS MORE RELIABLE. As a matter of fact, it will be less reliable if it is under 5000 per month and was good at 10,000 plus.

Answer: Re-blinking DV run simulation 22-15 will tell you what the problem is. Most likely, you will then need to do 44-2 44-3 and 44-01 to fix.

Answer: Do a by-the-book full PM, including drum change— no short cuts.

Subject: Savin 9130 paper feed problem

Question: The paper is fed to the registration roller which doesn’t start turning until the paper buckles. Is there any adjustment for the timing of the registration clutch? I am getting copies with a fold in the paper.

Answer: That is a classic relay clutch symptom— replace the relay clutch.

Question: The clutch has been replaced and is new. There is a delay between when the paper crosses the light barrier finger and the clutch engagement. How do I adjust the delay for a jam-free operation?

Answer: Well, you probably need the reg clutch then, which is not quite as common, but not unusual. To answer your question, the reg code is 42.

Question: The registration clutch is the one I replaced. Adjusting the registration (Sim 42) has no effect on the folding. Which one is the relay clutch? I ran simulation 45 to “adjust the buckle” but regardless of the setting from 0 to 15, the copies all have a 5/8” pleat 2 5/8” from the leading edge.

Answer: Is the drum rotating?

Answer: Sounds like the paper feed clutch or relay clutch (both in line in front of the reg clutch) is dirty/bad and overdriving the paper, causing the fold.

Answer: The relay clutch is on the relay rollers, the rollers that push the paper to the Reg rollers. It’s a smaller square shaped clutch about 3 inches to the left of the reg clutch (looking from the back).

Question: Can anyone tell me what it means when the display flashes “OF”. It will do it in the middle of a run, pause, and then continue where it left off after you press start. I cannot find anything in the service or operator manuals. Thanks

Answer: Memory overflow usually occurs when there is a print system installed. Possible memory board problem.

Answer: I think that the exit area is too full of paper.

Answer: Most likely, the customer is copying from colored originals or there is a lot of picture image, not text, on the originals and memory is being overflowed.
