In social media many of the responses when it comes to print quality is to do nozzle checks, head cleanings, and Power Cleanings. However, no one really talks about print head alignment procedures. Since printers are mechanical in nature the print heads can get out of alignment just like your car can get out of alignment from regular use, wear, and tear. A print head alignment procedure is not harmful to the printer and uses a very tiny amount of ink, as opposed to running multiple cleanings and Power Cleanings.
Print head alignments are a best practice that should be run on printers periodically. There’s no magic answer to how often they should be performed, but at the least probably every month or two if the printer sees significant use and certainly after projects that might demand many prints in a short period of time.
