[comp.laser-printers] Texas Instruments OMNI 2115

L.S.

From time to time I read some comments about the OMNI2115. At my institute
we have two af these. One for more the a year and a second one for about a 
half year.

- Some time ago I read something about the OPC getting bad after about 4K
  pages  about a quarter of the end of the page. I hev a similar experience
  for our oldest, but this occured after about 9K.

- About a month ago we had some problems with the paper feeding mechanism
  This was displayed as: "Jam at transfer". The technician
could not repair it at out location, so he took the 2115
with him. Later I heard that some kind of sensor was
malfunctioning, and had it replaced.

- Last week, however, we had the similar problem. I hope
this does not contnue.

- Does anybody have an opinion concerning a maintenance
contract??

We have two OMNI2115's that are almost a year old.  We had a problem with one
of them jamming frequently that was fixed by replacing the OPC cartridge
(some little pieces of rubber fell out of the cartridge when we removed it).
As I recall, it finally got bad enough to produce the "F.Error OPC" message.

We also have the problem of faded spots appearing near the bottom of the page.
I don't think this is closely related to pages printed, rather, it seems to
come from ambient light leaking onto the end of the belt cartridge.  Awhile
back, someone posted a suggestion that the belts be stored in darkness for
several weeks to rejuvenate them.  We have been doing this and it works.
(Just be VERY careful not to scratch the belts while exchanging them).

Another persistent thorn has been paper tray selection.  According to the
manual, selecting LIMITLESS should cause the printer to change trays when
the current tray empties.  It doesn't work on ours.  TI insists that it
works, so the problem must be in our software.  Has anyone else tried this
feature?
