I try to load a roll and get the message "Paper loaded incorrectly. Remove paper", so I remove the paper from the rollers. Then it responds "Initializing. Please wait." Then "Ready for Paper." Then I load the paper. The carriage head then starts across the track a few inches and stops. The error message then reads "Switch power off. Check printhead path (Type 2)". This pattern repeats each time I try to start the plotter. What should I do? Thanks much for you help.

This is a velocity shut down. You need to turn the power off, open the cleaner door on the right side and slide the cleaners out. Now move the carriage assembly by hand from right to left and then back again. Do you feel and obstructions or maybe bumping action. If bumping action, the belt is bad and needs to be replaced. It just tight in different sections you may just need to lube the slider rail. Use a good synthetic oil. Also clean the encoder if everything else is ok. There has been an issue with the tube assemblies on this plotter where over time they can bow out and cause path issues.

thank you for the detail answer, sir! I have a number of clients with this same problem. And yes, these printer are workhorses, but every horse needs maintenance over time.
we used 3in1 oil, and cleaned the rods first

I know this post hasn't been used lately, but I am having the same problem. What type of lubriacant is best? I have silicone grease, would that work? Also, what is safe to clean the encoder? Thanks in advance for any help.

Do not use grease on the carriage shaft. Clean the shaft with alcohol, use a light machine oil, HP sells a synthetic oil but it is pricey. The encoder just needs to be blown off, or wiped with a cloth or a brush to remove any dirt that may be stuck in the sensing holes, as well as the sensor blown out.
