ImageClass D530 printing issues

Hi

I seem to have 3 issues all of a sudden with my ImageClass D530

1.  It will only print if I request the print job twice (however, if I am printing multiple jobs about a minute or 2 apart, then it will print subsequent print jobs without issue... if it sits for more than 5 minutes I am back to having to request the print job twice)

2.  I am getting 1/2" black horizontal line across some of the pages - sometimes it appears as "stretched out text", other times it's a solid line

3.  Sometimes I will get a page that will be 1/2 of one print job on the top, and the bottom half will be from a different print job. 

Thanks for your help on this!
