External table height adjustment for printer systems
View Patent ↗An external table height adjustment technique for a printer system is disclosed. An operator can align an image gap between a printer table of the printer system and a printhead carriage via a height adjustment mechanism. The operator can perform the table height adjustment while a belt is installed on the printer table and media is loaded on top of the printer table. A height adjustment assembly is secured onto a supporting frame of the printer table such that an adjustment component exposed beyond an edge of the belt can raise or lower a portion of the printer table where the height adjustment assembly is secured.
1. A method of adjusting the table height of a printer system, the method comprising:
installing a belt onto a printer table of the printer system;
determining an amount to adjust an image gap between the printer table and a printhead carriage based at least partly on running a measured original image gap through a response surface model of an alignment system by (1) attaching one or more dial indicators to the printhead carriage and measuring distances and angles using the one or more dial indicators and (2) electronically outputting, by the one or more dial indicators, the measured distances and angles to the alignment system; and
adjusting, by the alignment system, an image gap between the printer table and a printhead carriage while the belt is still installed on the printer table by tuning an adjustment control that raises or lowers a height adjustment assembly within a support structure of the printer table, wherein the adjustment control is exposed beyond an edge of the belt.
2. The method of claim 1 , wherein tuning the adjustment control includes rotating an adjustment nut mechanically coupled to the height adjustment assembly.
3. The method of claim 1 , further comprising loading media onto the belt with vacuum pull before adjusting the image gap; and wherein said adjusting occurs while the media is loaded on the belt.
4. The method of claim 1 , wherein said adjusting includes pushing or pulling a rod attached to the height adjustment assembly.
5. The method of claim 1 , wherein said adjusting includes adjusting and aligning image gaps at more than one locations over the printer table by tuning more than one adjustment controls that are exposed beyond the edge of the belt.
6. The method of claim 1 , further comprising:
measuring an original image gap between the printer table and the printhead carriage at an adjustment location over the printer table; and
determining how much to tune the adjustment control corresponding to the height adjustment assembly at the adjustment location based at least partly on the original image gap.
7. The method of claim 6 , wherein each of the one or more dial indicators is positioned at one of printhead nozzles of the printhead carriage.
