Dear HP-Seqer's,
While troubleshooting a problem on one of our G1005As, we found a
manufacturing defect involving the exhaust line running from the waste
bottle
arm to the back panel of the sequencer: The drooping line had an oily
liquid
collected in the low spot and the exhaust gas was bubbling through the
liquid.
Shortening the line until it was just barely long enough to reach solved
the
problem.
To see if the problem was just a local one, since one sequencer had
the
problem and the other didn't, two other labs were contacted. One lab
currently had the problem and the other had corrected it several years ago.
Obviously, if you are running an HP sequencer, then you should get out the
flashlight and inspect the line.
Surprisingly, the problem had little effect on the sequencer's
performance, whereas the same problem on the old ABI's (and possibly the
new
ones) would be fatal. The robustness of the HP N-terminal method has
always
amazed me, but you rarely hear about it in this forum. As the old Timex
watch
commercials said, "It takes a licking and keeps on ticking".
