[mod.computers.laser-printers] Imagen 12/300 problems

ras@RAYSSDE.UUCP (Ralph A. Shaw) (03/21/86)

We have had some problems with our Imagen 12/300 laser printers
that we have not been able to get a satisfactory answer from Imagen
about.

The first problem is that the hot roller on the fusing units
tend to heat up to the point of melting the plastic coating
off the roller (at the center point only).  Indications of the problem
are black smudges down the centers of the printouts.  

We have two units and at present each one has melted the rollers
twice in the last two months.  The total number of copies on either
unit are 80K pages or less, done in the last 9 months.

The second problem is slippage of the OPC belt within the OPC cassette
unit.  This causes the false indication of paper jams.  One solution
to this problem is to clean the rubber roller and the OPC mark itself
every 3 to 5 days, in our environment.  In addition, the OPC belt seems
to only last for about 8000 pages vs. the advertised 20,000 pages.

(Imagen, are you out there?)
Any suggestions or help would be apreciated.
