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 five sheets of paper.
2
Wait approximately five seconds.
3
Print five more sheets of paper.
To maintain printer feeding reliability, repeat this cleaning process every time you replace the black cartridge, more
often with some media. Failure to follow maintenance procedures for your printer could cause jamming, poor print
quality, feeding problems, and fuser problems.
