Printhead removal
1. Remove the top cover. See “Top cover removal” on page 4-14 for
more information.
2. Remove the right side cover. See “Right side cover removal” on
page 4-12.
3. Notice the alignment of the printhead at each screw.
4. Unplug the printhead cables at locations J13 and J14.
5. Remove three screws (A) securing the printhead to the cross brace.
6. Remove the printhead.
Install the new printhead in the same position as the old one. Always run the
registration test following replacement, and adjust as needed. See
“Registration” on page 3-21.
Check skew caused by the printhead by printing the Quick Test. For E340
and E342n, see “Quick Test” on page 3-22. For the E238, E240, and
E240n, enter Diagnostic mode (see “Diagnostics mode selections” on
page 3-11), and select Continuous print—simplex Tray 1.
The printed test sheets have horizontal lines and two vertical lines.
Printhead misalignment causes skewed horizontal lines, but not vertical
lines (that is, the vertical lines will be parallel to the vertical edges). If the
ends of the horizontal lines on the right side drop down from the left side to
the right side, adjust the printhead clockwise to the printer. Adjust the
printhead counterclockwise if the horizontal lines rise from left to right.
