Absolutely, I'll indeed remember this one for life.
Tick!!!!!, thank you very very much 'polar bear' and all those who've contributed to this thread. It has worked! It was indeed that very small door below the right side door. I did nothing else but...
Thanks Ruben for the quick reply. Fortunately there's similar machine nearby...mp2000, and I did swap both the drum unit and toner hopper, they're both OK. Even the one from working machine when put...
Hi folks, I've the above model of Ricoh displaying...Add Toner message which doesn't go away! Of course we've replenished the toner...original OEM,closed the door properly. I checked the door switch...
Thanks iowatec for your reply. It makes a lot of sense. First, the generator's output is good, since there's another riso fr3910 also being powered by it and its working well. I'll have to really...
Background info: The machine is run on a petrol generator, no problem. Now it doesn't power up, completely dead. Panel blank, no anything, no nothing.I made preliminary checks on the power supply...
Just give it a try, science is both theory and practical. By doing so, your findings will help other forum members with similar challenge. You could also check that rubber at the spigot of the drum...
Absolutely right. And if I may ask, 'why is the USA so concerned about north Korea developing and testing nuclear weapons since it's a different far away country from its borders?'Simple, when those...
Try another ink motor?
Yes, the test mode 101 operates the ink pump allowing it to supply ink to especially a dry cylinder. Operate it after doing all necessary cleaning as advised by fellow techs. Having a manual at hand...
Try this: Disassemble the drum to access the ink distributor, remove it from unit and clean it with relevant solvent e.g kerosene, making sure that you blow the ink distributor with your...
Just follow my advice from previous posts.I've passed through a similar fire from exactly the same model of machine.Make adjustments between the master loading motor tension and that of master...
Not encouraging. That would be wasting available resources both technical and human. A Tech's job just like in any engineering work is to cut down costs. I do own and operate a small copy and print...
Well, the machine was invaded by rats,ate much of the wire inside. The finisher unit was the most affected. Ignoring advice from fellow techs here to discard the finisher unit and allow machine to...
Have seen the video, I had a similar challenge multiple times. Your problem is uneven rotation of the write roller and associated rollers. Open machine rear to access the cutter motor, adjust the...
Open the right front cover and check that the pulley on the master loading motor is not loose. The pulley gear has hex drew that losens with time. Check belt tension as well. I would also check the...
Eeh! Servicing a copier even in the 'world of the dead', it must have been the most chilling and frightening experience! I hope the morgue attendant was at your side throughout that session.
Thanks LA TECH for your views, as I said earlier in my post, i did change the write roller from a known working one of an FR3910iu and it did not make any difference in image quality. I actually...
Honestly I admire your 'adventures' dear fix, you must now be 'Battle hardened'.
Well, I thought it wise to share this 'success' with you folks. I recently handled a Riso GR3750 which was specifically referred to me with an 'Image shrinking' problem. Some other techs had tried...
Thanks teckat for your input, I will have to do a detailed fault diagnosis of the PCB and see what I can come up with and post it here accordingly.
Hi folks, i have a canon i-SENSYS 3010 which is not powering up. I did some preliminary checks on the main board, fuses intact, major suspect components like fusible resistors are also intact. Its a...
The loudest "Bang, Bang,Bang" I've ever had was from the Risogragh GR and RA series digital duplicators. This happens when the machine's clamp unit for some reason fails to operate...open and close...
No big deal there. 'Mergers and acquisition' is the name of the game. It's happening all over the world.Just recently,one of the largest banks here, (name withheld), with over 46 branches all over...
