Grain direction
Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of the
paper, or grain short, running the width of the paper.

For 60 to 135 g/m paper, we recommend grain long stock. For papers heavier than 135 g/m
preferred.
Maintenance procedures
If the print quality begins to degrade when printing sheets of vinyl labels, we suggest you follow the three cleaning steps
below:
1
Print 5 sheets of paper.
2
Wait approximately 5 seconds.
3
Print 5 more sheets of paper.
To maintain printer feeding reliability, repeat this cleaning process every time you replace the black print cartridge, more
often with some media. Failure to follow maintenance procedures could cause jamming, poor print quality, feeding
problems, and fuser problems.
Troubleshooting
The following table provides solutions for some common card stock and label problems. See your printer documentation for
