Expert Trouble Shooter

The most common problem with HP designjets is the wearing out of the carriage belt. We stock most belts and can replace yours within one business day. The trailing cable which is the flat wire that connects the carriage to the main board is the second most common issue.

We keep a good supply of these as well and can replace it for you within one business day. The service station on the 500/800 series is also a common problem. If you see a 21:10 error code this means the service station is bad. This is the printhead cleaner and it gets gunked up often.

Another common error code is 79:04. This means either the firmware is out of date or the printheads are expired. We can update your firmware and/or replace your printheads.

IF your machine is less than 7 years old it usually makes sense to repair rather than replace your machine. If your plotter is older than 10 years and is anything beyond a bad belt, you are better off upgrading your equipment.
