HP Designjet 510 error 86:01 Error message
The HP Designjet 510 86: 01 error message indicates that the printer carriage is no longer able to move properly. In 90% of cases, this is caused by wear of the Carriage Belt (a rubber drive belt).
The solution: First, check for dirt on the guide rail and gently wipe the rail with a dry cloth. For the guide to function optimally, the rail must be a bit greasy.
If the problem persists, take a good look at the drive belt. If there are any missing rubber pieces or the belt sags slack, it must be replaced. This replacement can be carried out with the help of a supplied manual.
After replacing the belt, the printer can work well for years, the error 86:01 is fixed.
Be sure to buy the right belt. The HP Designjet 510 is sold in two versions, 24 and 42 inches. The right dimensions are always on the drive belt.
