One cleaning sheet is fed and ejected to clean the rollers. 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 printhead cleaning. If five or more cleaning operations fail to solve the problem, replace the BJ cartridge with a new one. Use paper of B5 size or larger for the nozzle check pattern printing. If you CAUTION use smaller paper, the platen may be smeared with ink. NOTE To abort the nozzle check pattern printing, press the POWER button. The printer will switch itself off after ejecting the paper. 3-16
