Method and system for avoiding bottom of page printing artifacts
View Patent ↗Method and devices for reducing printing artifacts. In one embodiment, a method includes directing ink onto a medium, the medium having a trailing edge; tracking the position of the medium in relation to a nip roller; adjusting the direction of ink onto the medium a first time when the trailing edge of the medium is in close proximity to the nip roller; and adjusting the direction of ink onto the medium a second time.
1. A method of reducing printing artifacts, the method comprising:
printing on print media using a first set of nozzles;
controlling movement of the print media out of a feedroll nip by a normal index move;
printing on the print media using a second set of nozzles; and
setting an adjusting index move equal to half a height of a printhead plus the normal index move.
2. A method as claimed in claim 1 , further comprising moving the print media by the adjusting index move.
3. A method as claimed in claim 2 , further comprising ensuring the print media comes out of the feedroll nip during the adjusting index move.
4. Computer-readable media containing instructions for:
determining a first set of nozzles;
printing on the print media with the first set of nozzles before the print media exits a feedroll nip;
determining a second set of nozzles;
printing on the print media with the second set of nozzles after the print media exits the feedroll nip;
moving the print media out of the feedroll nip; and
setting an adjusting index move equal to half a height of the printhead plus a normal index move.
5. Computer-readable media as claimed in claim 4 , further comprising instructions for providing directions for moving the print media by the adjusting index move.
