Printer head contact error.

SOURCE: How do I clean the HP designjet 110plus printhead

You need to go to the hp download site and download the System Maintenance Utility Software. Its free, but you need it before you can clean the print heads. also, for some reason it works best when hooked to the network, not directly to Computer.

This can be caused by a faulty electronics module, trailing cables, printhead carriage assembly, or ANY of the stepper motors.

try this...

Switch the printer off from the back, and then disconnect the trailing cables from the electronics module.
Switch the printer back on.
If the error code changes to '010037'
If the error stays as 010036, change the Electronics Module.
If it is 010037, replace the trailing cables, then the carriage assembly.
