Performing the Connection Methods
• Never open the center cover or raise the lever during printing. Opening the cover or raising the
lever will abort printing.
This section explains procedures for connection methods to reduce image quality defects such as black
lines and white lines as well as variation in concentration. There are two connection methods, the
connection method for the print heads and the media feed.
When executing print-head alignment, the test pattern for adjustment is printed. Note that the test pattern
cannot be printed on narrow media. When executing print-head alignment, use media having a width of
297 mm (approx. 11.7 inches) or more.
• Printing the test pattern consumes ink. Perform this function only when necessary.
• Perform no other operations while the test pattern is printing.
• An error will occur and test pattern will not print if:
• There is a misfeed.
• One of the machine's covers is open.
• The machine is performing maintenance operations.
• The machine has run out of ink.
• The machine has run out of media.
• Before adjusting, ensure that there is no media floating or skewing. If such issues occur, feed the
media from the [Origin Setting] screen to reset the media or to resolve the skewing.
• Before adjusting, ensure that the heaters reach a temperature appropriate for use.
• If nozzle clogging or bending lines occur, the machine cannot perform the adjustment successfully.
We recommend performing head cleaning before adjusting.
• This machine cannot execute print-head alignment automatically for transparent or colored media.
Perform it manually. For details, see page 109 "Performing the Connection Method for the Print
Heads Manually".
• When using white ink, you cannot perform print-head alignment. Set [Print Head Alignment] to
[Off].
