3.4 EEPROM
The EEPROM stores data such as the total page count, BJ cartridge
installation/removal count, total waste ink amount, and customsettings. The page
count and waste ink amount indicate the frequency with which the printer is used.
The EEPROM must be reset when the logic board, EEPROM, or waste ink absorbers are
replaced. See
"Part 5: 4.3 Waste Ink Absorbers" (page 5-6)
for details of replacing the waste
ink absorbers.
3.5 Cleaning the BJ Cartridge
If the printed page shows faults such as white lines or fragmentation, print a nozzle
check pattern to see if the print head nozzles are clogged. If they are, operate cleaning
function for the BJ cartridge to clear the nozzles, as described below.
In addition to cleaning the print heads using online operations via the printer driver,
the BJC-7100 also allows you to manually clean the heads using the
RESUME
button.
Note, however, that if you perform manual cleaning, the heads of both BJ cartridges
installed in the printer are cleaned. (You can clean just one of the heads if you use the
printer driver.)
Manual Print Head Cleaning
1) With the printer power ON, press the
RESUME
button until the beeper sounds
once.
2) The
POWER
indicator blinks. (Any paper in the printer is ejected.)
3) Both BJ cartridges installed in the printer are cleaned.
4) On completion of cleaning, the beeper sounds and the
POWER
indicator lights
continuously.
Deep Cleaning
If after performing normal cleaning, the print quality is still not satisfactory, perform
deep cleaning.
Deep cleaning uses more ink than normal cleaning.
1) With the printer power ON, press the
RESUME
button until the beeper sounds
twice.
2) The
POWER
indicator blinks. (Any paper in the printer is ejected.)
3) Both BJ cartridges installed in the printer are deep cleaned.
4) On completion of deep cleaning, the beeper sounds and the
POWER
indicator lights
continuously.
The printer also automatically performs cleaning operations at the following times:
1) The first time the power is turned on with the
POWER
button after the AC power is
connected when the heads are not capped;
2) When a BJ cartridge or ink tank is replaced;
3) When an ink-out error is detected (ink-out detection → cleaning → ink-out
detection → display)
4) The first time the power is turned on with the
POWER
button after 72 hours or
more has elapsed since the last cleaning or deep cleaning operation;
5) When the dot count exceeds the prescribed value during printing.
