3.5.1 Cleaning
With the printer powered on, hold down the RESUME button and after confirming one
beep, release the RESUME button. The cleaning operation will start, cleaning both
(right and left) print heads. If you want to clean only one print head, connect the
printer to the computer, and perform the print-head cleaning from the computer
using the printer driver utility.
3.5.2 Nozzle check pattern printing
With the printer powered on, hold down the RESUME button and after confirming two
beeps, release the RESUME button. The nozzle check pattern printing will start,
feeding a sheet, which must be of B5 size or larger, from either the auto sheet feeder
or the manual feed slot, and print a standard pattern using all nozzles of both
installed BJ cartridges. If print defects are detected in the test print, perform print-
head cleaning. If five or more cleaning operations fail to solve the problem, replace
the BJ cartridge with a new one.
