3.4 Control Buttons
This printer has two control buttons, the RESUME button and POWER button. These
control buttons are used to perform cleaning the BJ cartridges or for setting service
mode items.
3.4.1 Cleaning the BJ cartridges
If the printer image is blurred or a print defect occurs, such as a white streak, print a
test pattern to see whether or not the BJ cartridge is clogged with ink. If nozzles are
clogged with ink, carry out the procedure below to clean the BJ cartridge and clear
the nozzles.
In addition to cleaning by online operation from the printer driver, this printer also
supports manual cleaning by pressing the RESUME button on the control panel.
Note, however, that when manual cleaning on the control panel is performed, both of
the BJ cartridges installed on the printer are cleaned. (Cleaning of only one head or
cleaning of each individual color head is possible only from the printer driver's
maintenance window. For details, see "Part 4: TABLE 4-7 CLEANING EXECUTION
CONDITIONS, CLEANING TIME AND INK SUCTION AMOUNTS" (page 4-25) .
Manual cleaning on the control panel
1) When the printer is turned ON, hold down the RESUME button until the beeper
sounds once.
2) The POWER indicator blinks. (Paper is ejected when the printer contains paper.)
3) The two BJ cartridges installed on the printer are cleaned.
4) When cleaning is finished, the POWER indicator lights.
Manual cleaning is performed cyclically in order F, B, D, F, B, D and so forth.
(However, note that if 10 minutes has elapsed since the previous cleaning operation,
manual cleaning is canceled, and the next manual cleaning operation is started from
F.)
