HP Latex 850 Troubleshoot Image Quality issues - Page 7

The objective is to make sure that there is no pause between the tiles. When using the Queue mode in the HP Internal Printer Server, there is still a small time between the jobs, which could add more variability between the lengths of the tiles. 4. In order to make sure that even the first tile has the less difference of length versus the other ones, add a top margin of 50 cm. In case you have to reprint one tile, in order to ensure the length will be as close as the previous jobs: ● Make sure that the substrate and also the ambient temperature of the printer are the same as when the previous job was printed ● Add a top margin of 50 cm But in any case, when having to reprint a tile later, there is a higher probability that the length will be different compared to the other tile length. The total length repeatability depends on the substrate, and the contents of each job (mainly when the substrate is reacting differently depending of the ink density). How to fine-tune and check the printer configuration (in case of color mis-registration): A series of crosses can be printed on the full width of the substrate for one meter and then the calibration can be done 'on the fly' through the Print Adjustment button. Make sure that the Printheads are aligned. To do this print the Printhead alignment check (printer -> Printhead alignment -> Verifyalignment and click on print,(refer to the maintenance and troubleshooting guide). If required, perform the Printhead alignment and recheck that the Printheads are aligned. 1. Browse to the following directory: C:/users/currentlogin/Documents/HP IPS/Substrate Creation.
