Wont except tape or occasionally when it does after awhile of use it pops up "remove tape" or "remove cassette".

It should work with a second press of that button, after the stop is pressed. If it doesn't there must be something wrong with the mechanism that removes the tapes.

check the top of the tape cassette if plastic removable tabs missing it will behave like a read only cassette if missing sticky tape can be used to cover the holes to make cassette recordable.

Loose belts and lack of lubrication. Dual cassette decks are built to minimum standards so that it does not take much to push them over the edge to be non-functional. It is almost like they should provide a tape deck repair course with these types of units as it is most certain that you are going to need it. They want you to throw it away and buy another one. This is where the throw away economy started.

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.

My advice is that you should by a cleaning cassette. Put this in the camera and run it for 10 to 20 seconds only. running the cleaning cassette for a long time may damage the head.
good luck!

I have had this same problem too. I fixed it by taking the tape transport out of it and removing both capstans with their flywheels and oiling the capstans. However this only fixed the problem for a few months. Maybe you need to more a most soild oil since i used just regular motor oil.

You can open the cassette cover and spray inside the upper left side of mechanism(closer to the back) with contact cleaner spray,because there is a rec inhibit switch.If it's not damaged and just dirty you solve your problem ,but if is damaged it needs replacement.

when mechanism pops out to eject, wait until it completly comes out, deattache battery immediately, and Pull lever as per below mentioned picture. Cassette door will be open and place cassette. Close it and attache the battery. Camera is ready to Record or Playback.

I had this problem, and here is how it was resolved.

My cassette would not pop out when I opened the door with the camera turned on. When I turned off the camera and opened the door, it slid out much further, but still failed to pop open so that I could remove the tape. Then it slid back in.

Remove the battery, and have the camera off, but make sure the power cord is connected. Open the door until the tape slides out further than at other times. (Note: It intermittently slides out further when the camera is off. Sometimes it will not slide out any further than when it is on.) When the tape is slid out as far as it will go, quickly remove the power cord. The tape will stay in the slid-out position. Now, at the bottom side of the tape door there is a curved channel for a small pin to slide in. This channel has a 90% curve at the bottom of the channel to catch the pin, which holds the door closed. Push that pin back a little (toward the lense) to get it to go around that 90% curve, and the door will pop open so you can remove your tape. The ribbon of your tape will be jammed in the camera a little, so you will have to be careful and move the ribbon around a little until you can get it out freely.

This worked for me twice. I did not try putting a tape in again.

I hope this helps.
