At the request of @Soboyle and Mark @MHMG from the LL contribution
LINK, I will go into more detail about my previous problems with the Z9 + 44 ".
The HPZ9 + 44 "was delivered with the firmware JGR9_06_19_41.2.rfu.fmw. This is also the current firmware - both in Europe and in the USA. The firmware is from 11 Nov. 2019 and has a size of 1.6 GB current HP Utility has the version 6.0.9.4660 and is from 4 Jun 2020.
Own paper profile problem:1. Own paper profile created with the setting stark (stark means heavy). Hahnemühle PhotoRag Pearl mehr Tinte (more ink) 320g
2. After loading the roll, selecting your own paper profile and density measurement, the profile is back to "normal"
When printing, there is head contact.
Manufacturer paper profile problem:1. Upload manufacturer OMS File via HP-WEB Access
2. Confirmation from the printer
3. Confirmation by the web tool
The paper profile does not appear in any selection (the current one is not overwritten either) and can therefore not be used. So no solution to get the desired paper thickness.
Star wheel problem:In the official firmware (JGR9_06_19_41.2.rfu.fmw) the position of the star wheel is not adjusted - regardless of what you set in the profile.
If you want to test the star wheel position in service mode, the test fails completely.
HP has provided me with a beta firmware JGR9_06_20_06.1.rfu.fmw. With this firmware, the star wheel position can be easily adjusted.
Here is the test in service mode for the star wheel position.
All other problems remain.
Firmware errors:The HPZ9 + often has firmware errors. System errors are usually often unspecific and not documented. They depend on the respective firmware. There are notes in the service manual, but there are no precise ones.
Here are a few examples.
The errors usually occur with the HP Utiliy. So when I read and write access to the printer.
It looks like this on the computer:
My impression is that the firmware / software is not ready or was partly taken from the Z3200. If you e.g. a default ICC profile (not yet profiled) exported from the HPZ9 + and then looking at the TAG targ/text in the profile you will find that this has 864 patch fields and not 464 patch fields as after profiling.
