"ROS MOTOR" problems on a 8500
LaserWriter (light version)
As usual, I cannot be responsible for any damage to
your machines when you will experiment the following
No more way to print:
1) an "ROS motor" error is displayed
2) the jam and the "load paper" lights are blinking.
This problem was solved a long time ago, -> the
quality of the snapshots is not so impressive ;-) and the

the "gete.net" website...
The problem is issued from a contact which,
theoritically, has to be done by the cartridge's small nail
(lowest yellow arrow) onto the switch (highest yellow
-> several solutions:
1) remplace the switch: cost money
2) add a thickness onto the cartridge's contact nail:
same operation to be done for each new cartridge???
3) add a thickness under the switch itself.
I decide to put extra thicknesses under the switch (see
yellow arrows to locate where I put the thicknesses).
I do not detail how to dissamble the printer and to
extract the culprit switch: it is a long procedure... and my
camera ran out of power supply ;-)...
I take the switch's footprints onto carboard and cut out
...on which I have to make holes for the screws and

Even if it is difficult to dissamble (and re-asemble) the
machine, the small pieces of cardboards helps you to nearly
save 250 euros!
