Checking for Nozzle Clogging

If printing is faint or affected by banding in different colors, make sure the print head nozzles are clear by printing a test pattern to check the nozzles.

Note

• By default, nozzles are checked at fixed intervals.

Paper to Prepare

When using rolls

An unused roll at least 10.00 in. (254.0 mm) wide

One sheet of unused paper of at least A4/Letter size

   • Loading Rolls on the Roll Holder
   • Loading the Upper Roll on the Printer

   • Loading Sheets in the Printer

2. Tap Maintenance on HOME screen.

   • Touch Screen

   The Maintenance screen appears.

3. Tap Nozzle Check.

   A confirmation message appears.

4. Tap Yes.

   The printer now prints a test pattern for checking the nozzles.

5. Check the printing results.

   If the horizontal lines are not faint or incomplete, the nozzles are clear.

   

   If some sections of the horizontal lines are faint or incomplete, the nozzles for those colors are clogged.

   

   Note

   • Because CO has no color, printing is performed on top of the black pattern. Check if the dark gray areas have lines (A) in the CO pattern.

     

   If horizontal lines are faint or incomplete, execute print head cleaning.
