I think putting a simple switch on the red "roller wire" would approximately do the same result (even if it's definitely not the origin of my bug).
I'm affraid I won't be able to give you a more precise answer before next year... my eBay seller has received his order, but I doubt he will be able to send me the lexmark during new year's eve (and even if he cans, European postal services are totally cluttered these days)

Your problem is really interesting. There have been many times I would have liked to have been able to cycle the printer without actually printing anything. Usually I just print a dot or something small. I should have time later this weekend to see if I can replicate the problem.

Hi Marc,
Well, it is certainly resolvable . The hack does work and has been repeated numerous times. I'm not sure I would replace the laser mechanism, though, without knowing how to realign it.

Hi Mark
The situation here is still the same.
The diags given by the service manual don't helps a lot... after having verified all connectors (and particularly the roller's wire), things haven't changed. The usual suspects are : optical block, High voltage power supply, PC Kit... I think I would be able to write maintenance guides for Lexmark :-))). I would have felt more comfortable with a real maintenance guide, indicating voltages and signals patterns. Or even a simple schematic.
As the sum of most of the parts is higher than the cost of a whole e260 on eBay, I'll buy a "new used" one that will gave me all I need in term of spare parts. And if the problem is the PC Kit itself, I will probably "offer" a modified e260 to my Radio club :-) (first law of Lavoisier and hacking : nothing can be lost, everything can be transformed :-D )
Thank you for the time you spent and your help. I'm still optimistic, this small problem will be solved.
