Ernie,

Broken tents can be caused by the developer, but it may not be your root
cause.  First check to see if the lamination pressure has been cranked up.  It
has been while, so I don't remember the recommended pressure settings, but you
resist rep. should have that number.  If you have white rings around the holes
after lamination, this is an indicator the lamination could be contributing to
the problem.  Additionally, check how long it has been since you recoated the
rollers.

With that said, you need to look at the quality of the spray inside the
developer.  If you have a Chemcut (with oscillation) then make sure the cone
nozzles all have the spinners inside so they don't shoot.  If you have a ASI
(non-oscillating) then it is critical that the fan nozzles are clean and are
producing the correct angle of spray.  For either type of equipment, be sure
the nozzles are clean, sized correctly (all the same flow rate), and do not
show wear.  Additionally, if the equipment has a build-up of photo scum, it
can retard the spray angles, so be sure the equipment is cleaned regularly.
For all equipment a range of 25-30 psi should be plenty of pressure.  High
temp. or/and high concentration can add to the problem.
