Agfa Grand Sherpa 50 woes

[PDFninja]

As I do remember that error means: IDFE_LEVER_UPMOVE_06 22226

Recommendations are:
DBS Error, LEVER Up move Illegal Sensor ! (Check
LMDS)
The DBS detected that the Lever Down Sensor did not change during a
'Lever Up' movement.
Check the Lever Sensors.and Lever Motor System.

i have it stripped down to near skeleton. i had cleaned all the sensors. ( last time we had tumble issues it was paper dust & grease on one of the lever sensors.)

the lever seems to barely come up into the top sensor. it looks like 4 sensors monitor the positioning on the right hand side ( looking from front).
when i managed to get a 1 sided flat out i then got a E073 Err Xcurrent.
which in the hardly useful manual that came with it says a current overflow for the media motor or something to that effect.

i noticed a red blinking light bouncing off a tan bracket where it looks like a tech would plug a diagnostic tool. Naturally i unscrewed that box removed the warning high voltage cover and found what appears to be the brains etc.

i found 4 LEDs near that plastic tan bracket no doubt used for quick diag. the electric box is hinged and hangs from the underside of the printer. so from top down i have 1 green LED (#1) and three red LEDs(#2-4).
the green one never lit up during start up (that i saw) the #2 blinks constantly even after start up and the #4 looks like its trying to blink. (i didn't actually see labels on them just numbered them here for ease of explanation.

off to the left of the box are 4 more LEDs staggered up & down in red green red green. only the greens lit up during start up then nothing from them afterward.

So between the motor current error i'm getting sometimes when i don't tumble and the red lights on the circuit panel i'm leaning toward the motor or something regulating its power being my problem over a sensor.

i'll update this incase someone ever comes looking for answers to the same problem.
the only draw back is we are upgrading to apogee prepress 5 (maybe 6) some time.
so the bosses are relucktant to bother fixing issues we have now. our palladio is also having issues related to air suction for loading plates.

we can work around both issues but its' killing us time wise to hand load and reset these machines for each flat printed or plate imaged.

We had this error code and replaced the main board and the error went

[bmor]

We had the Grand Sherpa and the Anapurna, they're both gone now. We replaced the Grand Sherpa with the Roland AJ1000 and the Anapurna with a couple of Oce Arizonas.

HAVE NOT RAN INTO THIS PROBLEM YET...
maybe you've encountered this:
Tried to power AGFA 64" UIVERSAL GRAND SCHERPA...
I am receiving... CR E068 ENCODING ERROR.
MACHINE WILL NOT ENGAGE! WHAT CAN I DO?!

hello, and I hope you can help...

I've been running a Agfa Grand Sherpa for a few years now in a graphics department of a pharma company. It's been all sorts of trouble, but usually fixable with some intensive cleaning.

Yesterday however a new wrinkle developed, the prints coming out of the machine are demonstrating moderate to severe horizontal banding on the cyan and black. I'm checking the print heads via test-print regularly, but nothing is showing up "wrong" there, yet the quality of the proofs coming out of the machine is deteriorating steadily.

Where is a good place to go to troubleshoot this machine? I'm growing steadily more desperate, thanks.
