Sharp JX-9460/MicroLaser Pro toner/drum mysteries deepen
Folks:
My elderly neighbor has a Sharp JX9460 which is out of toner, near the end of its second toner cartridge in its long and successful life...so I tried to help. If you've seen my previous posts, I was under the impression that it printed until it was completely out of toner, but that was a misunderstanding. It was still printing perfectly when last tried, but the toner low message had been seen. Ten years on two toner cartridges seemed fair, time to order another. Following recommendations of 1 new drum per toner, I ordered a new toner (JX96ND) and a new drum (JX96DR) and set out to make this printer last another 5 years. I assumed refilled/remanufactured parts were all that could be found for this very old printer, and would be OK. Information gathering: My understanding is that the JX-9600 series is the same engine as the TI MicroLaser Pro series, so I gathered info on both. I found many (20 or so) postings and documents that described the fuses on the cartridges, ways of replacing or defeating the fuse--reset mechanism, the various ways of manipulating the internal counts in printer, the fear of having to buy new cartridges if you made one mis-step or put an old cartridge in the printer, yadda yadda yadda. (Long and frustrating saga omitted) No matter what I did, with the new cartridges installed, the printer reported "REPL. TONER". Sometimes immediately, sometime after doing what seemed like a lot of initializing and some hopeful noises. Ultimately, I gave up on the new parts and boxed them for return to the vendor, and I started to prepare my neighbor for the reality of buying a new printer. Hmmm... maybe I should put everything back the way it was....and ...one last try... Lo! Behold! The printer works perfectly with the old supplies. Probably, the new cartridge WAS defective in some way. (Someone said that maybe the re-filler failed to put developer in along side the replenished toner, but I can't find any further information on that.) But the information I gathered just didn't seem to match what I observed. For example, I never found a fuse on a cartridge. (I'm an engineer -- I know what fuses look like.) I never found a press-two-buttons method of defeating the fuse reset mechanism. The information about how to restore the internal counters was not effective. Most surprising: None of the fiddling around --and I did A LOT of fiddling with the internal settings-- seemed to have made a bit of difference. When I powered the printer with the old cartridges, it simply picked everything up and continued. So does anyone have the definitive story on replacing the toner and drum on a JX-9460? Are refilled/remanufactured cartridges risky? Are there reliable workarounds/resets/fuse defeats for _this_ printer? Thanks, Henry remove 'zzz' |

Hm. I have a TI microLaser 600. Some folks think of the wrong printer.
They say there is a "fuse". But actually my printer doesn't have the stated fuse. Instead there is a photo darlington around the used fuse cartridge. If the cartridge is dirty of toner, then the light cannot pass back and the printer reports "replace toner". Simply clean the cartridge with COLD water. Maybe that helps - Henry Henry wrote in message ...

Hi!
Hm. I'm a little confused about all your text. Last week my printer was saying "Toner". I will describe what I have done: 1. squired the toner/OPC unit. Helped the last occurences. Nothing! 2. Opened toner cartridge and shiffled all the used toner off the wasted toner bottle back into the toner cartridge. That's the way I "refresh" approx. half the toner I bought before Nothing! 3. Cleaned the now empty used toner bottle under cold water several times. The plastic is now transparent!! Works!!! I never seen the optical sensor. The printer is very small inside. I read about it in a newsgroup. Yes, my printer is a TI microLaser 600 (exactly written). Have 2MB RAM, Postscript, Parallel port and LocalTalk, no extension card installed. Ciao - Henry Henry wrote in message ... Henry: Thanks for your reply to my post: in article , Henry at wrote on 9/14/03 7:53 AM: Hm. I have a TI microLaser 600. That would be a "MicroLaser _Pro_ 600" yes? Some folks think of the wrong printer. Yes, it would seem so. We are discussing printers containing the JX 9600 printer engine. Some people incorrectly include printers containing other engines, I think. For example, there is a JX 9500 printer engine. Maybe people think it is the same. From what I have read, the JX 9600 is the same as the JX 9400 and JX 9700, but NOT the same as the JX 9500. It is confusing. Some of the documents I found were from professional printer service companies. I would expect them to do a better job. They say there is a "fuse". Right, a fuse on each cartridge. If I understand correctly, the fuse is connected to two of the spring contacts. Maybe the fuse is covered with tape. When the cartridge is first inserted, the printer finds an electrical path.

Neither you or I have seen it in actual practice, it seems. But actually my printer doesn't have the stated fuse. Instead there is a photo darlington around the used fuse cartridge. I guess you see a combination sensor in your printer. One part that sends out light, and the other senses light that is reflected from a nearby surface.

If the cartridge is dirty of toner, then the light cannot pass back and the printer reports "replace toner". Simply clean the cartridge with COLD water. That sounds like a good solution. In my case, the old cartridges are grey-colored, and would reflect light reasonably well. The new cartridges are all black-colored. So this method would not be very useful for the new cartridges, I think. Hmmm, also these darlington sensors would seem only to be useful with the printer powered. I think they are inactive when the printer is turned off, so I'm not sure how useful they are. Thanks, Henry remove 'zzz' Maybe that helps - Henry Henry wrote in message ...

Henry:
Thanks for your response on this post: in article , Henry at wrote on 9/21/03 5:26 PM: Hi! Hm. I'm a little confused about all your text. Last week my printer was saying "Toner". I will describe what I have done: 1. squired the toner/OPC unit. Helped the last occurences. Nothing! Sorry, what did you do with the toner/OPC units? 2.

Cleaned the now empty used toner bottle under cold water several times. The plastic is now transparent!! Works!!! I have not located any such bottle, so there's something strange going on. I downloaded two manuals for the TI 600 Pro. There's no mention for a used toner bottle in _them_. I never seen the optical sensor. The printer is very small inside. I read about it in a newsgroup. These sensors are quite small and it is quite possible you would not see it unless you know exactly what to look for. Yes, my printer is a TI microLaser 600 (exactly written). Have 2MB RAM, Postscript, Parallel port and LocalTalk, no extension card installed. I finally gave up and returned the cartridges for credit (I hope!) from the vendor. I did finally see a fuse on one of the cartridges. It is a cylindrical projection maybe 1/2 inch long, part of it is clear; resembles a very low-wattage light bulb. If you wiggle it a bit, you can see how it plugs into a two pin socket on the cartridge. I'm glad you had success washing the used toner bottle.
