Nakamichi RX202 reversing calibration issues
Hey guys,
I've been having a heck of a time trying to calibrate the reversing mechanism on my nak RX202 deck.
As mentioned by the helpful folks on Tapeheads, I've set the cassette well into the deck on the "A” side and have set the CAM gear to the far end of the limit. (Clock-wise). Once that is done, I proceeded to calibrate the A side by unplugging the eject wire and shorting CAM B test point to ground.
Once that is aligned as per manual (and using the corrected method of using VR503 for the A side alignment). I proceeded to short both cam B and cam a wires to ground and made the adjustments to side B.
The main problem is that once I pull the shorting cables out, the A side tends to continue to attempt to close and you can hear the motor binding. It does not stop. When attempting to reverse to the B side, the mechanism reverses, but before it reaches the end, it immediately goes back to side A and binds the motor.
Hopefully someone out there can help sort this issue out. Thanks!

This is a Quick Test video to show the record feature of this deck. it is unique in the sense that you have to enable the rec open option and then hit the record button twice to engage the record feature on the deck. Otherwise everything else works normally. it is a very unique design! it was made to play with their 8000 series system, but is perfectly fine with a normal stereo system. Note: wh...

This tape deck seems to work fine for a few seconds when cold, but then stops and goes crazy when hitting the eject button. Power supply from LD4 seems solid at 5v

Purchased this locally from a guy who I'm certain has tinkered with it. Replaced the power supply and the belts. Deck was playing for about 2 minutes and decided to go nuts! Any help with this would be appreciated. Thanks!

I figured mine out. There are three gears and each has an arrow align all three up. Turn the tape holder so its between A and B with the tray out. The tricky part is keeping the belt on but I managed. Put the belt on the larger gear first and stretch it a little onto the smaller gear as you lower the lid while keep the three arrows aligned. I marked all three arrows with a marker so I can see then better. Then it was very simple to adjust the tray using Cam A and B. Make sure you do the adjustments 2 or 3 times like the manual says.
There are alignment indicators on the 2 gears. They need to be centered
Yup, they are centered. But once I pull out the jumper cables for testing, the mechanism motor starts to bind. Believe me, the arrows are perfectly in alignment. 😎
@@botelhdaI just lifted the table slightly and if you move the gear left and right you'll hear it start to bind - center it - set it down and eject. If it doesn't, adjust slighty, took me about 20 minutes and it works perfect now.
I’m having the exact problem
Did you find out?
I just bought one of these 8000's and it won't come out of standby. Any idea why?
I have one of these for sale, with box in working order. Please comment if you would like more info.
cosha hermosha!!!!
Hey there, I watched your video in hope of comparing with mine! Whenever it gets out of Stand By mode it makes a humming noise… it’s not coming from the speakers, it’s an ambient hum - I wonder if it’s normal
It's normal. Its the capstan motor that is humming. You may want to add a drop of oil to the capstan motor shaft as it should quiet it down a bit. But that's likely the hum. :)
FC is right. The mode 'switch' potentiometer may well be at fault. I repaired mine, but I had other symptoms. The only problem similar to ur's is, with my one, the stop light kept on flashing. Good luck!!
Фантастика!!!👍👍👍
Hi Dan! Great Vid! I've got an 8004 in my garage, buried somewhere. Are you saying the headphone out is actually off-tape, and not source? It's possible to mod the deck to monitor off tape? That's the only reason I've not bothered with fixing mine!
Ahh, it's actually not "off-tape" as in a 3 head deck. This is a 2 head deck, so no tape monitoring while recording. This deck has an annoying feature in when you engage the recording option, you don't hear the audio from the deck. (It has to do with the way their receiver is setup). You can enable "audio out" while recording by making a mod on the deck. I'll have to check with mine, but I believe the headphone out works for monitoring while recording to tape.
Where’s your shop can I send a unit to you for repairs?
I'm in Brampton, Ontario Canada, but not accepting any shipped repairs at the moment. Thanks for inquiring.
Cheaply casted belts buy better ones
Issue was resolved by tweaking the blue pot. Found out a week later that it was the torque control ont eh deck. The belt was a new pioneer electronics factory replacement belt...
These are terrific scanners but Nikon abandoned them. If you run a Mac, you need to go elsewhere for software, like VueScan. And then it works great.
how long does it take to scan a 36exp roll in full ress? aprox
I've never measured a roll, but with having all slots taken up for a 35mm frame on the tray (12 exp), it's a good hour or so. All depends on how many times oversampling is used as well as whether ICE is used or not. ICE takes a bit longer per neg scan.
Il faut passer un coup de soufflette sur le négatif avant son entrée dans le scan, mon camarade !
Allway's problems with those Japanse equipment.
You need to remember when these were made. There's no a deck in the world which wouldn't need maintenance after 30 - 40 years later. The reason we see so many repair videos and discussions about Nakamichi decks is due to these reasons: 1. They were ridiculously expensive when new. People with "normal" salary couldn't afford them. Now people actually can buy them even though they are still pretty expensive. 2. They are real high-tech equipments and not just regular hi-fi. Considered the best you could have get if you got money. Sure there were other high-tech brands too. 3. They are sought after and keep their price. So it's wise to repair them. For example with 200$ repair, even "low end" Nakamichi decks could cost at least 1000+ dollars easily in working condition. 4. You can't find new cassette decks as good as Nakamichi made new today. Not even if you are willing to pay a fortune. That's why Naks or other high-tech brands like Revox from the 70's and 80's are also needed in the studios. And yes, they still produce new music cassettes even today. 5. Regular hi-fi decks like consumer models of Philips, Technics, Akai, Teac, Tascam etc. are mostly just trashed/recycled if they broke, no reason to fix them usually. If you see Nakamichi written in somewhere, you know it has value even in broken condition as there's not hi-fi models of Nakamichi, only high-tech.
@@showstopperrob1097 Studers are superb of course like Revox but "if" they broke, considered difficult to repair and as they are more rare than Naks, getting spare parts might not be that easy. Other than that many consider them best of the best.
Ouch! This guy know how to kill a coolscan. Never ever connect or disconnect fw cable in power on state.
Fortunately the FW chipset didn't get killed. The one in this laptop is low voltage... not like some of the older FW400 ports that are on some mac towers and PCs. There are times when you can fire up the laptop and the scanner is not visible. I don't think I'll be rebooting just to see if the scanner made connection with the laptop. This is probably my 6th coolscan unit. Never an issue with testing or scanning on this laptop.
@@botelhda so please add this information to your description for all coolscan newbies.
thanks! any tips on the pc mac? which one, what to install, what to keep in mind?
Yes. As this is an older scanner with a FireWire interface, you are best off with finding an older mac computer with a running copy of OSX snow leopard, leopard or tiger. Anything that is newer will not work, as there's no support for it. On the PC end, you'll be safe with Windows 7/32bit, but I have heard that people are running newer operating systems with a bit of tweaking.
Great video! I have had a 505 for 10 years which was rebuilt by specialist in CA. Long story short, I took to local shop (that did not have a clue) to find out why I was getting loud BUMPS every few seconds that maxed out the VU meters. They did something to speed the door open/close. But now NO PLAYBACK at all. Any ideas? The VUs light up and everything else seems good, but no signal output at all.
Interesting! I would check the volume pot and turn it a bunch of times to see if the audio will "kick in". Most likely it will require a recap from the sounds of it. It could be a loose cable, but it's odd that you are getting moving VU meters though. Do the headphones work at all?
Hello my name is Gabriel, first of all this message was translated by translate.google.com. I have a DCC Optimus DCT 2000 and I have not used it for years, now I put it into operation and the display does not turn on, I remember that to record digitally it has a function to turn off the display and avoid interference. Can you tell me what is the function to turn the display on and / or off? Thank you very much and best regards from Argentina.
I think it is something else. Does the unit play tapes? It could be that you need a remote to turn off/on the display...(or something is wrong with the display somehow)
@@botelhda Yes, the unit plays both digital and analog tapes, the point is that I don't remember what is the function to turn off the display. I consulted Radio Shack and they replied: "Hello and thank you for contacting RadioShack. Unfortunately we do not have a manual available for this vintage DCC tape deck. Thank you. Ed". Thanks for the answer, I'll see how I solve it. Greetings from Argentina.
Sorry my friend, I do not believe there is a way to.turn off the display. Besides, it should turn itself on after powering off/on the unit. There is a display button on the remote control, but I think it is for track/time display. Good luck!
Nothing like revox tape deck nakamichi they get mess up very delicate it sound good but the RX they get mess up fast they look cool my got mess up i got to send it to fix got two of them n they mess up unbelievably i told they were bad ass until i bougth 2 revox made in Germany that is a tank of tape deck n record beutiful omg i was shok how sharp n clear it record is like a tank tape sound beutiful way better than the nakamichi RX series im going to send it to fix cus they look cool n i pay a lot for them oh revox no belt drive a motor waooo awesome tape deck love it always wanted one then i bought anorher one cus i like the sound of it n they build like a tank
Everything you wrote is a total crap. You definitely never restored any deck. I spent with Revox longest time to keep it restored and it is still not 100% good to my standards.
Is this working with the latest iso? I have Nikon ED 5000 it works with Imrik's Software..
I'm just using it with the nikonscan 4.0.3 software on snow leopard. Works great and I get full use of hardware ICE as well as NEF file creation
Way to slow
Unfortunately, good things take time. ;) You won't get a faster, cleaner and better result on any other desktop scanner, especially one that does both 35mm and medium format scans.
What do you use for transfer that is better?
@@bradvincet1848 Epson V850 scanner with Dust and scratch remover color correction also Its called Digital Ice software Then throw in the AKVIS Retoucher and you have perfect crystal clear scans. The machine you are showing is way out dated. Thanks Mike CTS
As an RX-505 owner, this made me anxious! Did you manage to get it fixed?
Nope...sold it off as parts. Was just too frustrated with the damn thing, and that is after replacing all the caps as well as the power supply. Most times when it acts like this, it's almost always the alignment of the tape drawer gears. Not in this case...
Unfortunately, no. :( I ended up selling it to a guy who bought it for parts. I did hear from him later on, and he had mentioned that it has some serious processor issues. I'm pretty happy it left the roost as I spent way too much time on it.
GREAT VIDEO, WAS THIS IMAGE FROM A NEGATIVE OR A SLIDE? YOU DID SAY NEGATIVE DURING THE VID, SO AM ASSUMING THE SCANNER CONVERTS IT?
That was done from a negative. :) The scanner will scan negative C41 color/BW as well as positive negatives that you would see on slides such as Kodachrome. This is really the best scanner with hardware-based ICE that's out there at the moment, which is quite amazing for a device that is as old as it is.
I did some research on this. There’s a potentiometer inside that turns when the tray mechanism slides in and out. It’s near the tray motor. I believe this helps tell the deck where the tray is at any given time. This pot may simply be dirty and causing erratic behavior. Try flushing it out using deoxit or another suitable control cleaner.
I laughed, I cried! That’s both hysterical and horrifying at the same time. Have you exorcised the demons yet? Do you have the service manual?
Yes, I dug thru the manual...however it was not playing nice so I sent the deck off to a higher authority in the US. Turns out one of the microprocessors was shot....and was destined to be a parts unit. :(
hahah that auto tape flip was the shit back in the late 80s early 90s..
This guy's a reject! Throw away your computer and stay off the internet

Actually, it is indeed working fine. I've scanned many a negative on this fine scanner. Why would you suspect that it is broken?
it looks like you forget to say it was broken... ;)
Not going to happen. Nikon scan 4 will not run on lion, period. Best bet would be to get snow leopard running on a separate partition and scan using that method, or install vuescan to run your scans.
It can be loud, depending on how many passes, and how fine of a scan you select...
is the scanner pretty loud?
How did you install the software Nikon Scan 4 on the operating system Os 10.7?
Simply switch to a different sw. Try VueSan for $100 and it works with all the Mac OS. Am using in 2021 with Big Sur (11....)
