I've been working on a Panasonic W1505 Word Processor and am hoping that I can find a Panasonic Word Processing Guru that can answer a couple questions. 

 

1. I replaced the original, belt-driven, 3.5" Floppy drive (Matsubleepa EME-213KL) with a mechanical one, but when I try to format a disk, it always fails. Since I've updated the drive, will this be able to handle the 1.44 MB disks, or just the 720 KB ones? Are 720 KB disks even still available?

 

2. The vertical scroll and horizontal return don't seem to work very well. It tends to jam when scrolling the paper up and when it does work, the carriage doesn't always go all the way back over to the left. It rarely stops in the same place twice. Is it probable that this is just an oiling issue? If so, what kind of oil should I use?

The EME-213 drives were used in many Panasonic and Technics units, they are not made to a standard PC FDD specification, so cannot be directly substituted using one. Specialist repairers may be able to modify a modern drive to substitute, but it's not certain, and only those who do that type of work could say for sure. The drive will still only function with 720K storage capacity, but will probably utilize 1.44M discs if the media identification hole is blanked off. I haven't had to source 720K discs for many years (my 1990 Ensoniq keyboard uses them), so can't say if they are still obtainable.

The printer portion is probably suffering from hardening of the rubber feed rollers, and the slide lubricant going tacky. Depending on how advanced the rubber roller deterioration is, cleaning with a rubber rejuvenator may cure the feed, and the slide surface should be cleaned off with a solvent such as isopropyl alcohol, and a light machine oil (e.g. sewing machine oil) applied.

For example comments about the FDD, see toward the bottom of this page:

Thanks for the info, Platypus!

 

I put a small piece of electrical tape over the media identification hole and was able to get it to work! I can live with the 720K capacity on this one.

 

I was hoping that it was just an age thing with the printer portion. I'll clean it up a bit and get a better look at the rubber parts.

Sounds like you've been lucky with the drive, being a word processor, the unit possibly runs a specification more similar to a PC than other units that used the drive.

I had to use an adapter that I special ordered from Germany to get the newer drive to work. Ironically, the replacement is a Panasonic, so maybe that helped. Not sure if I can link it on here, but it on ebay under the headline "KORG X3 X3R i4S Floppy Belt Matsubleepa EME 213KRJ, KR, Adapter 24 Pin"

Ah, using an adapter no doubt explains it. And using a Panasonic (Matsu*hita) drive should give the greatest compatibility.
