SP8100 - Hanging on print command

[Polarbear]

I have received a SP8100 printer that is testing my sense of humor!

It boots OK and makes all the right sounds and actions until ready state, then the fun starts!

If you try and print ANYTHING, even a meter count, the DATA IN light comes on and the display reads PRINTING. The laser spins up and.... it waits, then spins down (without print engine starting up).

It will stay in that state, and nothing prints??

We have changed the following from a known working machine:
Controller
BICU
PSU
I/o Board

I am really out of answers here! Any ideas?

check if there is an SC code, update the firmware..

Thanks for the reply.

Forgot to mention that we updated the firmare, re the RTB about machine freezing, before changing the controller.

We also replaced the fusing unit and door switches out of desperation, but no luck

HDD / memory?

[Polarbear]

The machine does not have the hdd option, only 128mb mem (both controllers I used have the same setup).

Have you tried reloading the drivers, or checking for an updated driver or drivers?

I have not even tried printing from a pc. This is all happening from the device op panel! I cannot print meter count, or config page: all have the same result.

Is it possible to print out of the service menu (like SMC lists)? Have you swapped the PCB's including NV-Rams or did you run the tests with the NV-Rams of the faulty machine all the time? You might try a complete memory clear (after NV-Ram backup). It's also possible that there's some kind of weird restircion configured - try checking the web interface.

Hi Gift

I have also thought along the restriction route, but (to me knowledge) there is nothing I have not changed (except for motors and clutches) that could still hold any restriction data, as I did straight swops of board for board, not removing nv-rams.

Have you tried swapping the laser unit? You say the poly mirror spins up, could be the machine isn't receiving the laser write start signal.
