How to prepare PageWide printers for shipping? (PageWide PRO 477dw, OfficeJet PRO X576dw)

[Kryonero]

I noticed that PageWide printers require specific measures for shipping.

In printers that were damaged during transportation, there seems being a horizontal metal blade that hangs, near to the printing nozzles.

My questions are

1.  What is the required procedure before transportation ?
Does it suffice to remove the cartridges from their lift ?
I remember there was a way to prepare the printer for later use on another site but have always be reluctant doing that as fearing an unpredictable setup time once on site.
N.B. When moving the printer for an event, I expect it to be ready to use once on site, and not to get gray hair because of endless initialization. This is especially true when you have to deliver 4 printers or more for ticketing or alike on the same day.

2.  What makes printers using PageWide technology so fragile for transportation?

The print bar seems being the very fragile component.
I don't understand why it is so fragile, as the printing head is fixed and not moving horizontally like in a consumer desktjet printer. Well, there is the cartridges lift. Is the weight of the cartridges the problem if left within the lift?
There seems being some metallic blade that han gs. I don't understand why it is not better attached.

3.  Can someone explain and possibly post pictures of what happens in case of inadequate preparation for transport?
I really would like to understand what happens within the printer and how to fix it.
Pictures from repairs welcome.

I really like the PageWide printers, except their fragility.
Thanks.

1. You can find shipping instructions here  https://h10032.www1.hp.com/ctg/Manual/c05263194.pdf 

2. all printers are fragile for transport if they are not prepared properly and transported properly.

3. depending on the situation, if roughly handled, the printer can be recycled in the waste

One of the biggest dangers with pagewide is the liquid ink. Unlike a laser printer that will tolerate some tipping motions. Ink can go everywhere so keeping the printer level is a must. Removing the duplex/waste ink container and putting it in a plastic bag can help. In terms of physical damage, I have seen smaller pagewide printers moved without the head locks with no damage. That said, being move in a vehicle and not packed into a box and left to the whims of a courier or mover who will likely not pay close attention.
