Plugged into a UPS in a surge protection outlet.
Test report has the top T registration mark 1/8 inch from the top of the page, and the bottom one is 7/16" from the bottom. The left registration mark is 1/8" from the edge of the page, and the right registtration mark is 3/8"
If it matters, the typed information is:
- Vertical Cartridge-to-Cartridge Alignment Setting: -24 0
- Horizontal Cartridge-to-Cartridge Setting: -96 0
- Black Bidrectional Printing Alignment Setting: 6 0 0 0
- Color Bidirectional Printing alignment Setting: 3 0
I don't remember a major paper jam. It sometimes gives me problems doing the ink cartrdge alignment - where it won't do the scan part of the alignment process.
