I select print and the printer is ready, but a message pops up will retry in 30 secs. and nothing happens. It will print if I connect USB cord. But as soon as disconnect it will not print. I have turned it off to reset it for a minute and turned it back on and still the same problem.

SOURCE: MY HP DESIGNJET 500 DOESNT WORK

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 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

Perform the Carriage Movement test

check the ports first.. make sure that the printer is set as default ( make sure it has the green tick and the status "ready" or "online" on the printer icon in the printers&faxes. and if u want to connect it wirelessly, you have to install it as usb first before changing to wireless........

Have you put new cartridges in?

Dear sir;I believe you can try " cold reset", that's means going to clear all data from the printer memory and sets all the defaults back to the factory settings.performing a "cold reset" resets the jetDireect configuraion. to avoid making changes to yourconfiguration, remove the jetDirect card before performing a cold reset. if possible, print a configuration page prior to performing a cold reset. this will document current settings for later reference.
to perform a cold reset;
1, turn off the printer.
2, while pressing "go", turn the printer on. COLD RESET appears briefly on the display, then INITIALIZING appears.after a few seconds, RESTORING FACTORY SETTING appears on the display, followed by OFFLINE.the cold reset is complete.
3, press "go" to return the printer online "ready " appearson the display.
Little bit complicated but is easy ,hope can take care your problem, GOOD LUCK! Let me know the resolve please!
HAVE A HAPPY HOLIDAY !!!

Sounds like their is not communications between your printer and computer. Could be a bad USB cable - swap out and see if that fixes it. If not it could be a faulty USB port on the computer or printer. You can check the computer USB port by connecting another device, but there is no way to check the HP's USB port. I would also check printer USB port for dust bunnies! If you're not able to resolve, I think it is time for another printer.
