I have a Tandberg 6000x r to r deck in grat shape except the rubber pinch roller has flat spot in it. I've found someone who can re-work the rubber wheel, but I cant figure out how to remove it from the...


It might not be a type that is meant to be fixed by that method. These type of pinch rollers are often held in place by horseshoe clips. Once that is removed the Roller assembly will often drop out. However to get the worn roller out, might require it being bendered out of shape to remove the wheel.

The tape plays songs so fast sounds like donald duck. The speed the tape is feeding is to fast.


Hi, the casette deck has a mechanical system (servo-driver) most of the problems that happen when in your case, plays song so fast is that you look at the pinch roller. The pinch roller is a rubberized free spinning wheel typically used to press magnetic tape against a capstan shaft in order to create friction necessary to drive the tape along the magnetic heads with a normal tape speed if the pinch roller brakes, get lost from his place or got dirty then you get this fast sounds play, check the pinch roller if still good in his place or clean his rubber with alcohol, then the problem should be fixed.

The rubber pressure roller which contacts the tape during play is broken . Can the spare part be sent. The tape does not move during play, forward and rewind. C.N.Rao, Mo: 09425609698 2, Herambh Homes,...


This is the PINCH roller which exerts pressure with the tape on to the CAPSTAN to pull the tape at the required speed. The capstan speed is servo managed and the pinch roller assists with the given pressure on the transport mechanism.
The rollers can get defective, the bearings/bushes can wear off and result in wobbling. the rubber also can become hard after a period of time resulting in poor action.
So the correct replacement is important to the mountings, remove and take along to get teh same type from an electronic spare parts store.

Cassette gets entangled, and does not play well


Cassette tape machines will occasional require maintenance after a certain period of usage. First open the cassette door and remove the tape and any broken tape remaining inside. Some models allow you to remove the cassette door allowing you to have better access to clean the unit. Next you will need to clean the capstan with alcohol and a Q-tip. The capstan is the metal post which the rubber wheel (pinch roller) pushes against to drive the tape across the tape head. Basically clean all the shiny metal parts including the tape head. Some of the tape residue may be difficult to clean, I use Tricloroetilene which has been regulated by the government, but you may try a product called Goof Off to clean the difficult parts, but it could eat the plastic and rubber parts so be careful. Next use a rubber cleaner on the pinch roller so you do not dry the rubber out, or it will become useless. The other problem is the cassette may be driven by a motor and belts. The belts may need to be replaced and the pulleys cleaned. For this you will need to disassemble the unit to access the belts but the cleaning of the pinch roller and capstan may fix your problem, if not you need to open it up to replace the main belt.

I have a Sony TC 630 Reel to Reel Stereo Tapecorder..Pinch Wheel is sticking and will only move when forced and brushes as well...Any help ?


Sounds to me like your Sony has a common problem among vintage reel tape decks..dried /frozen grease/ and or a lack of lubrication. carefully apply a tiny bit of fine lube oil, like 3in1, on the swing mechanism that carries the pinch roller...(you may have to remove the front metal deck face to fully access the swinging pinch roller mechanism) ) . do NOT get any oil on the rubber pinch roller..(best to make sure after by scrubbing the pinch roller surface with a cotton swab lightly dipped in non chemical household cleaner, like 409, or awesome orange i get at the dollar store. Then use the dry end of the swab to ensure the pinch roller is dry. .The pressure pads should swing upward and press the tape against the heads when in play/record mode..if they do not swing up, they are binding/ or out of adjustment....they are spring loaded so when the reel deck is in the stop position the spring loaded pressure pads are held down...play/record mode releases them to freely swing up and press on the tape against the heads.

The unit is eating up the tape!


Generally speaking, there are two reasons this happens.

[1] tape recorders have to move tape past the record/playback heads at a highly consistent and accurate rate of speed. What makes this possible is a rubber "pinch" or pressure roller and a spinning metal spindle. Tape is routed between the roller and the spindle, and when the recorder is in RECORD or PLAY mode, the roller presses the tape against the spinning spindle, causing the tape to move from the feed reel to the takeup reel. When the pinch roller and/or the spindle become coated with oxide particles shed from old tapes, they get sticky and the thin tape will begin wrapping around one or the other. THE SOLUTION is to get some cotton swabs and rubbing alcohol and clean the oxide (brown from cheap tapes and dark gray from better tapes) from both of these parts.

[2] many tape recorders use rubber belts and pulleys to turn the feed reel and the takeup reel. If the tiny rubber belt that makes the take-up reel turn is stretched, it will not wind moving tape fast enough, which causes tape to bunch up. If this is the problem (you will not be able to see the belts without removing the recorder's outer case), then you might as well junk the recorder.

If you see that the part of the rubber drive roller that contacts the moving tape has a ring of brown or gray coating on it, you

Re: Model PV-4523S


You can try cleaning it with a VCR tape cleaner to see if the pinch roller have build up on there. It could be that the motor isnt feeding the tape up against the recording heads properly and may need an adjustment. If you can take the top cover off, you should be to see what the problem is by the way the tape is being inserted into the machine.

Can't Print on Card


I had the same problem with my 3 year old HP Officejet 5610. Feeding heavy paper or white card stock would result in a paper jam. The card stock would start to feed, but then stop half way. The pinch rollers seemed to spin without advancing the paper, even if the paper was fed one sheet at a time.

Solution: Clean the rubber pinch rollers with isopropyl rubbing alcohol. Partial disassembly/reassembly required.

To access the rollers, remove the scanner plate:
1. Disconnect power, USB, and phone cables.
2. Open up the scanner sheet feeder by tilting it left.
3. Unlatch the scanner scanner feeder so that it opens completely vertical. Latch is on front hinge only.
4. Remove the 4 corner hex screws on the scanner plate. Remove the 2 hex screws on the sheet feeder. (I used a small flat blade screw driver in the hex heads)
4. Lift the plate and sheet feeder away from printer box. Disconnect the 2 flat cable wires from the circuit board.
5. Scrub rubber pinch rollers with alcohol on a swab. Dry thoughly.
6. Reassemble. (NOTE: This is a good time to clean the underside of the glass plate and the scanner head)
