Question: I need some ideas here. This
machine never jammed while I was there and if it
weren't for the jam history I would think the
customer is lying about it jamming. I cannot find
anything wrong. New rollers, sensors and clutches
working, paper seems ok. Still, I cannot go more
than a couple of days without jams. Here's a
rundown of the jam history:
Date Code Meter
11/09 EB50 649791 11/08 EB50 649776 11/08 EB50
649767 11/08 E480 649749 11/08 E550 649743
11/08 E550 649732 11/08 E400 649714 11/08 EB50
649679 11/08 EA70 649657
Prior to 11/08
you have to go back to the 4th for the last jam,
so the problem really just started. Even after I
left today the customer called and said it is
still jamming. Maybe someone else can see a
pattern here that I am missing. I'm not too
concerned with the jam door opening during a copy
run, but the EB50 seems to be the underlying
problem. I don't see how it can be multi-feeding
as the code seems to indicate, so I am at a loss.
Any ideas?
Answer: Based
on the error history you posted it seems like it's
happening every 20 to 30 pages on average. You
didn't mention based on the error history the
source it was jamming from. What does the 12 digit
error information in the right hand column of the
error history page say? Is the jam occurring from
the same source and under the same conditions
every time? I've seen that type of jamming
happening more from the LCF than the drawers. Also
how is the copier configured?
Question: All the jams in history were
out of tray one, LT, sort mode, single sided. No
jams out of the other paper sources logged since
about two months ago. At that time LD size in tray
3 (copier has 4 trays) was jamming because the
developer unit was bogging down the system and the
extra run time for the ledger would cause timing
issues. Replacing the developer unit solved that
issue. Prior to 11/08 there were a few document
feeder jams and a couple of intermittent finisher
coded jams all the way back to the beginning of
October.
Answer: I know
some of these ideas might seem simplistic so don't
take offense. Have you tried switching out the
paper pick up assembly with one of the other
working drawers and or the drawer itself? Have you
asked the customer to see if they could duplicate
the problem for you while you're standing there?
From all your answers to others' posts I'm sure
you are all over this as you sound like a VERY
qualified Toshiba tech.
Answer:
This sounds crazy, have you checked the
metal front door cheater? And little switch beside
it.
Question: Thanks guys,
don't assume I'm too smart not to miss something.
I appreciate the ideas and/or reminders. I haven't
swapped feed assemblies yet, nor did I pay much
attention to the front door switch or actuator.
I'm going back out there tomorrow afternoon so if
you think of anything else post it and I will
check it out.
Question:
Your suggestion paid off. Just finished the call
and I swapped the paper feed assembly from the top
tray with the one for the bottom tray. Seemed to
work fine, so I replaced the bad assembly with one
from a parts machine at the shop and ran about 300
copies through it with not a single jam.
At this point I assume the feed clutch on the
assembly was sticking, overshooting the next page
to be copied. I figured instead of wasting time
trying to narrow it down I'd just replace the
whole assembly. It works, is working, and I thank
you for putting me on the right track. I need that
sometimes. :)
Answer: I
had a problem with the transfer door switch. It
was out of place and would only cause jams when
duplexing.
Answer: I have
noticed if the letter size is on top cassette, it
jams the paper more often so I move the letter
size to lower paper cassette. Good luck.
