Z6100 PRINT IMAGE TOO RED

After 5 years, it's a pretty safe bet that the ink has dried up..
Here's a link to the HP how to videos: https://support.hp.com/us-en/product/hp-designjet-z6100-printer-series/3338748/videos
And here's the main 6100 page, with links to the manuals and other info: https://support.hp.com/us-en/product/hp-designjet-z6100-printer-series/3338748

Unfortunately you screen (computer or other ) isn't calibrated.
there is software mostly pro use this, but take a picture of a flat grey placard.
using your photo program to check the gamma settings and modify them until the grey on screen matches placard ( hold placard next to monitor). Then print out grey image.
important write down the gamma settings and when you put something to print check to see if these are close.

When you banding vertical do you mean Across paper feed direction OR With paper feed direction?
If its across the feed direction the chances are thje issue remains with the individual printhead, Print out a quality maintenance print to find which Printhead is not working as well as wanted, then replace ( or clean using the plotters control panel under image maintenance.
Errors along the feed direction can be down to Software/ Main Pca /

Hi

Did you try to calibrate on the same media what you want to print?

Try to delete any other calibrations stored. And re-calibrate the plotter on the same media or a plain paper.

DO RATE MY SOLUTION

you need to change the print settings in the program where you are printing, when you go to print settings the option should be in the dialog box where you choose the printer and page amount.

I had the same problem maybe this will help
Problems also may occured when you rotate your file in "Printhouse"
You should make the rotation before you rip your file.


(1) "HP z6100 Banding / Print Lock Up / Length Issues"
----------------------------------------------------------------------------

Symptoms:
Customers using HP DesignJet z6100 with firmware version 6 and the ONYX v 7.1 HP Driver may experience banding, printer locking, and printing length issues.

Cause:
The problem is caused by the varware data written to the HP z6100 hard drive.

Workaround:
If you experience any of the issues listed above, please contact HP Tech Support. They may need to do a Disk Wipe and should only be done under the guidance of a licensed HP Technician.

(2) "I'm experiencing inconsistent print lengths. Why?"
----------------------------------------------------------------------------

This issue is not RIP related. Check below for workarounds with various printers.

For HPs
On your HP's printer menu, set "Extended Margins". This should resolve the inconsistent print length.

For Encads
Onyx users who have Encads have recommended the following:
* Configure the X axis in the setup menu.
* Be sure to save your settings as "User 1" (without saving the settings, they disappear when you power down the printer).
* If produced in-house, add bleed to the image.
* If produced by someone else, print the image at 101% to bump up the finished size.
* Static and slippage can cause the issue.
* Canvas media almost always shrinks about 1/4 inch per 4 feet due to moisture and weave of the media.
* Talk to Encad -- they have a worksheet that explains how to best reduce the problem.

For all others
Most major inkjet printer manufacturers say that .5" on an 86" print falls within what they deem "acceptable". If your printer has Media Feed Calibration or some other feed mechanism calibration, be sure to do it... and frequently.

Please feel free to contact us if you have any questions regarding this solution or this case. Be sure to reference the case ID

Sounds crazy, but have you got the LM (light magenta) and M (magenta) tanks or inks mixed up?

Also - check the profiles, if you've got a colour profile set up, you may have applied it twice, which would make a magenta cast...

Reset your printer to factory settings and try again

Check printing preferences, print the picture as an image. Have you tryed update Acrobat reader?

Updated section
This red issue has been bugging me over the last week. I have now created over 50 A4 prints of my test file and it was after reading a post from Dan P that the answer came to me. I had been trying to correct the over saturated reds by reducing it in curves, levels and colour balance. Of course this was not the way to go, unless the image has an overall cast. The better method is to enter into Selective Colour within Photoshop and adjust just the red only. The values I have used are Cyan + 15 (this reduces the red), Magenta -5 (removes the remaining traces), Yellow +10 (removes the blue and warms up the skin again), Black -15 (lifts the image). Save the settings and reload them on future images. Create an action and use one of your Function keys to apply the Selective Colours. Incorporate the print command within the same action, this way you can be certain that the selective colour will be applied each time you print. This may not be the ideal solution, but for me it will do for the time being, until Canon come up with a new profile. I expect to make colour adjustments on most images and this is just one of those steps.
Use the Selective colour adjustment - it works The ink levels after 55 A4 prints - I don't think so As near perfect as I can get it Reels are now spot on Note: The above solution is a work-a-round which cures the excess red, once you apply the Selective Colour adjustment the screen image will not look right. The adjustment is applied to correct the printed version. Like so many things digital (and analog) you have to make adjustments to suit your own preferences. The strong vivid colours produced by the ip8500 will appeal to some, others may want to tweak their settings.
As a final note, I have just looked at the ink levels after 55 A4 prints and wow, this printer only uses the light Cyan and Magenta, the rest of the colours are all unused. I don't think so somehow. Canon, I think this does indicate that you have a problem with the driver and have another look at the profiles while you are fixing that.
Would I buy this printer?
Given that creating a new profile is not a major problem and I am sure a new one will follow very shortly, then yes I would buy it. Using Photoshop I have managed to correct the colours to suit my taste, however, some may like the bolder colours out of the box. The ip8500 features and image quality makes this printer stand out from the competition.
Price - £329
