Re: Taking apart DMP400 print heads.


Well, the print head on this '400 started to malfunction (the top pin stopped
striking), so I did take it apart.

Believe it or not, after cleaning it with alcohol and reassembling it, I did
reconnect it, but the head still didn't strike properly.  I believe some
silicon spray may have cured the problem after cleaning, but I bought a new
print head.  (I was doing a lot of bit-image graphics printing with the
machine at the time for fun, so it was getting some hard use).

They are *fine* little instruments that are mighty difficult to disassemble
completely and then reassemble.

I called a local company called Custom Cable, by the way.  They'll make a
cable corresponding to Radio Shack's part number which will supposedly work
perfectly in connecting the DMP400 to the AT.

I really just want to dump DOC files to the printer.  I have so much on this
AT already (Ventura Publisher, Aldus PageMaker, Q&A Technical Assistant,
BOYAN 4.0 comm program, Wordperfect, etc........ -- about fifty megabytes of
paid and PD software) with hundreds of pages of DOC files I want to get
printed out.

It's a 110MB hard drive, so I have enough room to last me a little while
longer.  Next thing to consider is making a backup....
