Apple Apple LaserWriter 360

Fixing Laserwriter Select Toner Cartridge Dots

This should apply to all printers that use the Apple M1960G/A cartridge

I have an old Apple Laserwriter Select 360 laser printer that I got for free about 10 years ago from my office. It has worked well all that time (during that same time I've gone through 5 Epson ink jet printers).
As you may know, the cartridges for this printer are no longer being made new by Apple. You can find older ones for really cheap on eBay. I had bought a few in the past, and when my cartridge began to go bad (streaking from a bad wiper to clean the toner off the drum), I tried a new one, and found it put a vertical series of dots down the center of the page. I tried another and it did the same thing.
I read some other posts about this, and most said to change the cartridge, but I tried three cartridges and they all did it. Some would say to get a new printer, but I don't believe in replacing equipment if it still can serve its purpose.
One post mentioned a rubber roller in the cartridge, so I took a look.
I wanted to fix these cartridges so I could continue to buy cheap old cartridges instead of the more expensive refilled ones (And who knows how well those will work).

(This may mess up your already messed up cartridge and will get toner on you and your work surface)

You need a cartridge that doesn't make dots, but can be out of toner or make vertical streaks (continuos streaks, not individual dots)

1. On each side of the cartridge, there are two screws that hold in white plastic pieces. These pieces hold in the drum. Remove the screws and plastic pieces from both the used cartridge without dots and the new dotty cartridge.

2. You now have to remove the drum, this can be tricky since you don't want to damage it, and it shouldn't be exposed to light for too long. You can press together the part of the cartridge opposite of the drum and it will separate the part that holds the drum slightly. Pry the drum out carefully to remove it. Don't scratch the surface or touch the surface. The drums seem to be more durable than I would have thought.

3. Remove the drums from both cartridges, store the drums away from light while you do the next steps.

4. Below the drum, you will see a black rubber roller. This is the problem. You can remove the roller by prying up on the spindle on the side, it should just pop out.

5. If you cartridge is making dots, you will see a dent in the center of this roller. You will notice that below this roller there is a plastic piece that presses against the roller, making the dent in the roller while the cartridge sits without being used. (Most of the NOS cartridges you buy have been sitting for many years.

-- I noticed that the cartridge I used to get my good roller did not have the plastic piece that makes the dent, so not all cartridges have this problem.

6. Take the good roller and install it in you new cartridge.

7. Put the drum back into the good cartridge. It is harder to get it back in than to remove it. Somebody may have a trick to get the drum back in. Make sure you press the opposite side of the cartridge to spread the part that holds the drum in apart so it is easier to get in.

8. Put the plastic pieces back from the sides that hold in the drum.

9. You cartridge now MAY work (mine did), and you have an inexpensive way to keep your good old printer going.

Good luck.
