Subject: Samsung 6345 Toner Supply Error

Question: Got a Samsung SCX6345 that gives me a toner supply error on multiple toner cartridges. I suspect it may be firmware. What is the latest firmware version on the 6345? How do I get my hands on it? Thanks. Answer: .76 is the latest, unless you have a fax kit in it. Then you should use .81. Your Sammy rep should hook you up. Otherwise it’s about 12MB for all three of them (main, ope, nic), a bit too big to email. Answer: Take out the toner and the drum. Look in the back. Put a finger on the + that sends rotation to the toner cartridge. Is it stuck pushed back? If so replace it. What happens when the cartridge is replaced? If the + is exactly lined up with it, it pushes it back and gets stuck. Answer: Yes, it’s the toner drive, the plastic will crack and cause the spring loaded drive to stick back and not engage the toner cartridge. You can get to it from the rear of machine. Question: Does anyone have the part number for the toner drive plunger that breaks? Thank you. Answer: The whole gear assembly is part#JC97-02681A; the cost is about $1.00-2.00. Has gear, coupling, pin, and spring.

Subject: Bizhub 200/250/350 toner bottle rotation

Question: Seems like I’m running into several DI2510 & Bizhub 200 series toner bottles that won’t rotate after a customer puts in a new one. The DI had the obvious popping noise, so I took it apart to the clutch and found NOTHING wrong with the toner clutch. Replaced it anyway and the bottle still popped until I swapped the bottle holder. Today on a BH200, bottle just never tried to turn; screen said there is no toner after 5 minutes of trying. Again, clutch is o.k., so I checked the bottle holder. It turns ok by hand, so I re-assembled and it runs fine now... Both machines have upgrade/mod clutches. ANY IDEAS? Answer: Sounds like the metal stop is not releasing the bottle all the time. It gets bent up and the clutch will just pop. Also make sure the e clip did not fall off the shaft of the lower gear on the assembly, which is common too. Answer: I just replaced the whole drive assembly on a 3510. Customer said they put in a new toner bottle and all of a sudden it started to pop. Found that the drive assembly looked as if someone tried to bend one of the gear shafts. Question: Definitely have seen the release tab bent up. Not on these. Also the e-clip was on. Sounds like the “Hopper Drive Ass’y” (clutch) was an older one. New style has an enlarged bottom of that “bent” shaft. The tab that releases the bottle (better visible with toner bottle and holder removed) will look like it is releasing, but just needs a little bend downward to be sure. Anytime the popping sound is heard, it could be the tab. Still, don’t know why the DI2510 worked with a new bottle holder ass’y. I could turn both by hand. Meter was about 80k. Answer: Katun toner? If so then the bottle will go in incorrectly easily. If not the customer is forcing the bottle into the machine without aligning the tabs up. I replace at least one of these a month. Question: Funny you say that. Yes. I brought Katun to replace ACM that has been running light solids, and the failure happened when they installed the Katun. It was in correctly, keyed o.k. Rotation/clutch issues usually happen with a new bottle, so I didn’t think much of the brand. We’ve had units fail with OEM as well (old style clutch). I can’t figure why the bottle would be a problem when the whole sleeve around the bottle rotates. Can you shed some light on that? Answer: There is no tab on the right hand side of the bottle with the Katun toner. This makes it easy for the customers to push the bottle when not aligned properly. Check the little nipple on the bottle and see if it has been crushed (even a little). If so, then that’s your answer. Also Katun gives light copies as well. You’re better off to stick with OEM if your customer is picky about CQ. Densi is using a bottle that is similar to OEM.

Subject: eStudio 523

Question: I have an eStudio 523 that is password protecting scanned documents. I am looking for the 0-8 code to turn it off. Answer: 08-623 needs to be a 0. Question: I set 623 to 0, but the password protect is still on. Do I need to reboot the computer? Or is there something else I am missing? Answer: If you mean that when you go to open the PDF that you have to enter a password then you need to turn off “SECURITY” on the scan to file control panel. If you are scanning via a template then you need to modify the template not to use secured encryption. Answer: You can also go into “Top Access” and admin and see what you can change in there.
