Very strange error. I wonder if it is a driver issue? There were Microsoft Updates pushed out last night. Contact HP Support direct. https://support.hp.com/ca-en/document/bpp03052 ..

You will have to buy a new cartridge Ink cartridges will eventually dry out and that's why HP puts a date on them so they can insure that they will work when you buy them. It's best not to purchase more cartridges than you need at any one time - that way your cartridges will always be fresh.

Does it show a Flashing X for the Black?

1 Replace the Ink Cartridge that has failed.

2 If the message continues to appear, clean the electrical contacts

inside the Ink Supply Station (power OFF the Printer first).

3 If the message continues to appear after cleaning the Ink Supply Station, replace the Ink cartridge again.

there problem with print heads replace print heads then reprint your file

color black ink is empty..or do the printer head cleaning procedure to the printer maintenance.

The service station on the printer has likely failed. This is the part of the printer that cleans the printheads to maintain print quality. Replacing this item requires diassembly of the printer and requires a certain amount of technical ability. If you are not afraid to take this on, you will need to contact HP and order Part Number C7769-60149.

If you are going to take this on yourself, post back and I can send you some instructions on the actual replacement of the service station.

Or contact an HP Designjet technician and have them replace it for you.

Try putting the print heads in a ziplock bag with a wet paper towel for a couple of days and then run head recovery.

you would need to purchase a service unit and replace this is a common fault

It seems you have a defective service station.
Exchanging it should solve the problem.

System Error: 86:01
Problem
Description:
Carriage-Axis shutdown.
Corrective Action: If this error code appeared but was NOT caused by a paper jam, then
try the following:

Too much friction in the Slider Rod. Enter the Printer Information
utility (→ Page 4-26) and check the Scan-Axis usage. If the
percentage is close to 100%, then lubricate the Slider Rod.

The Carriage is bumping into the Service Station. If the carriage
is stuck at the right hand side of the Printer and cannot be moved
out to the center of the Print Platen it is because the Service
Station cannot uncap the Printheads. In this case replace the
Service Station/Aerosol Fan Assembly → Page 8-52.

Perform the Carriage Movement test → Page 4-8. Okay this is the error code direct from the service manual. if lubricating the slider rod does not resolve this issue then you have other problems. more than likely the carriage belt is in need of replacement. check inside of printer for debris. check under the carriage assembly. see if you are able to move the carriage assembly smoothly from side to side. hope this helps.

check the catridges thier must be a mixing up of color when you were refilling the catridges

79 errors are usually bad firmware that needs replaced or updated. Sometimes it is simply a bad print job being sent. Check to see if only one print job is causing this error, or if it happens with everything you try to print.
