What to see in the Auto Printhead Alignment Diagnostics:
1. At the left we have four checks for the printhead to printhead alignment in scan axis direction
(Pen2Pen-Fwd or Pen2Pen-Rev). It is forward and reverse.
●
The top pattern is related to the front printhead (nearest to the user when doing the printhead
replacement).
●
The bottom pattern is related to the rear printhead (more far to the user when doing the printhead
replacement)
The area to check is the junction (marked with a “-”) of the black with the rest of colors.
2. The bidirectional check is at the top, marked as number 2 (Bidir)
●
The top pattern is related to the front printhead (nearest to the user when doing the printhead
replacement).
●
The bottom pattern is related to the rear printhead (more far to the user when doing the printhead
replacement)
Check that the lines are continuous without a gap. The junction is marked with a “-”
3. The printhead to printhead alignment in paper advance direction (PAD) is marked as number 3.
