After some heavy 3D printing, your ProJet 660Pro or 460Plus will ask you to replace the HP11 print head, this is normal and the HP11 print heads are considered a consumable. On average, you will go through the clear print head after every 1 – 2 full builds (8 inches high and 10-15 inches wide). The rate of which you replace the print head will vary depending on the amount of binder used by the print job but the print head will not exceed its life of 1000ml of binder on the clear head and 500ml of binder on the color heads. So, if you are near the end of the print head’s life, it is best to replace the print head before printing your next job.
When changing the print head most people are usually in a rush trying to send their print job, they usually just pull back the Fast Axis and replace the print heads without following the proper procedure. This can lead to issues with the print heads as well as the electronics like the Pogo card because the printer doesn’t have a chance to disable the power going into the carriage and put it into a standby state. Below I go through the steps to replace the print head the right way and go over some recommended cleaning steps to take while replacing the print heads.
The right way to change the print head is by:
Following these steps will ensure you will not accidentally short your print heads out and receive an error or even worse damage the pogo card. If you do receive an error, it is always best to check the print head to be sure the blue tape has been removed and it is seated correctly. If the error is persistent you can always contact us for support by calling our office or emailing us at 3DPrinting@microsolresources.com and send us the log file and serial number following the steps from our previous blog post.

As you use your Projet x60 series 3D printer more and more you may encounter a few errors here and there, this is normal and can commonly occur after long printing sessions. The reason for the errors can vary from not following the maintenance procedure and not cleaning the printer after every print job to various parts wearing out and reaching the end of its life. A lot of the errors are usually cleaning related so it is always best to follow the maintenance procedures and try to resolve the error using the troubleshooting guides found in chapter 7 of the user manual.
