Setting The Model; Adjusting The Head Position - Canon BJC-820 Service Manual

Part 3: OPERATION

2.6 Setting the Model

Since the logic board of this model is also used for the Japanese model BJF850, you
need to check the model name after resetting the EEPROM when replacing the logic
board. The model name is normally set to BJC-8200 after resetting; if it is not, correct
the name by the following method:
From the service selection mode, as shown in
"Model setting" and press the POWER button. Then, press the RESUME button the
number of times shown below. (Each time the RESUME button is pressed, the beeper will
sound once.)
Times

2 or more
After making the selection, press the POWER button, and the EEPROM will be set to the
model selected, followed by a beep sound. (The printer will return to the service
function selection status.)
After setting the model name, verify the setting is correct by checking either the service
test print or EEPROM information print.

2.7 Adjusting the Head Position

You can adjust the head position without connecting the printer to a computer. Among
the head position adjustments that users can perform using the printer driver utilities,
only the bi-directional printing adjustment is carried out.
After adjusting the position, verify the adjustment is made correctly by conducting a
service test print or EEPROM information print.
Use High-Resolution Paper (HR-101) or Glossy Photo Paper (GP-301), which provide
higher quality printing.
Adjust the head position in the following procedure:
1) From the service function selection status in
select "Print head position pattern printing" and press the POWER button.
2) The printer starts to print the head position adjustment pattern. (See
Position Adjustment Pattern (Sample)
After the printing, the printer will return to service function selection status.
3) Press the RESUME button 7 times to enter the print head position setting mode and
press the POWER button.
4) Determine which value is the best for the head by checking the printed pattern, and
then press the RESUME button the number of times listed below to set the head
adjustment value accordingly. (Each time the RESUME button is pressed, the beeper
will sound once.)
