P800 - Only Black Inks Laying Down

 

Hello,
?
Hoping for some insight/suggestions. This is in a school lab setting. Working with Print Tool and a P800 on a Mac Mini M1. IT forced another update, now to Sequioia 15.3.1. This resulted in the QTP800 printer no long showing up as an available printer. I uninstalled the P800 driver and Print Tool, and reinstalled. This was successful in terms of the printer being available. I reinstalled all of the quad files, and I remade the presets. All seemed fine. When printing digi negs, now the printer is only laying down black inks. I checked the quad files and those look as they should with some color inks. I restarted the machine again and all of the apps. No change, only laying down black inks.
?
Any suggestions? (Besides telling IT to stop updating OS in the middle of the term.)
?
?
Thanks,
DM

Are you at work now? Do me a favor and right click on the quad you were using and see if it reverted to read only. That happened to me, and the result was very dense black ink negatives as if Print-Tool was printing with no profile. I had to go and right click on every quad and change permissions to read/write in the school lab (which has stricter protocols).

Hi Chris,
?
That was a glimmer of hope, as that is something I would have overlooked for sure. But, all the quads are "write & read".?
Anything else? Uninstall again?

Did you check EVERY SINGLE folder in this order for read/write?

/Library

Printers

QTR

Quadtone

quadP800-QTP or whatever you call it.

Every single one.

Last time I updated I had to read write every single folder.

Because I “think” (but I’m not Roy) the Print-Tool is not accessing your profiles for some reason and printing an unprofiled neg even if the profile shows up in your dropdown menu.

Other than that I have no clue but this has happened to me at least four times on 4 different computers with three different printers ad nauseam.

FWIW, when I run into stuff like this, I nuke (delete) all the .quad files for a particular printer in /Library/Printers/QTR/Quadtone and then do some spring cleaning in my installation folder to get rid of .quad files with names like P8xx-last-desperate-attempt-77.quad before double clicking the install command again. It sounds to me like there may be some cruft in the files in the /Library folders for this printer. You can delete these .quad files and they will re-install

Hope this helps.

I agree that permissions is a likely suspect.

By far the easiest and best way to repair permissions is to simply
re-run the Install-QTR package. This automatically corrects all the
permissions in the /Library/Printers/QTR/Quadtone folders (fixes both folders and .quad files).

Update: Thank you for all the suggestions. I've nuked, reinstalled, and checked permissions. All seems right to me.?

Alan, here is one of the quad files. This is a case of it worked fine before the update, and now it doesn't

Why do you think it is only laying down black inks? Do the negs look different from before? The color inks in the profile are minuscule and only there to make sure some ink is going down all the lines in order to prevent clogs. They would not show up as any color as mixing those together in relatively equal amounts will produce a gray tone.
