HITACHI NT65MA4 When not used for a few minutes, doesn't want to fire. Holding trigger down for a few minutes and eventually fires. Then works fine? What causes long pause?

SOURCE: Printer Pauses every few pages, seems to print slower than it shouls

I seriously doubt that this is a network spooler issue but I guess there is a possibility. I was thinking that there is a setting with the paper on the actual printer or something about waiting to start the job until all pages are in memory. I have the problem with a 4300 not a 4100

SOURCE: Hitachi Framing Gun Not Firing - Bad Battery?

Does the fan run and the light blink ont he nailer? I have one that I just bought. I put in the wrong type of nails and got one stuck. I had to take the front apart to clear it and now the damm thing wont fire. The green light blinks and the gas cartridge is basically full, even the fan does run after I release the push lever, but no fire???

I wonder if yours is the same as mine did fire for a couple nails first just fine then got jammed...

I will try to charge the battery more.... MAybe like yours it needs a strong charge for the spark...

Adjusting the depth of the nail also changes the amount of pressure that is applied to the trigger pin. This is not actually a problem with the adjustment, however indicates that the orings in the gun are not completely sealing or is lacking lubricant. Adjust depth so that maximum pressure is asserted against the trigger pin. The trigger pin must be pushed all the way in very quickly to fire the gun. Test by removing the trigger and depressing the trigger pin by hand all the way in quickly. Enjoy

There is one main part that can be the cause of the problem.

The trigger. Check to see if there is anything out of the ordinary with this. There should be some moving components attached to the trigger itself. Is any part of the trigger touching the button in the body of the gun when safety is not depressed. If the lever on the trigger is pushing on the button, even a little bit, It will allow the gun to fire again and again.

Trigger may be dirty, as an electrical switch the contacts can be intermittent. Also check to see if the safety plunger is set to correct depth and moving freely. Dirt can build up here......
