The print yield in the table above is an average value measured in continuous printing, using the ink tank immediately after it is
unsealed, until the ink is out. Ink yield may vary depending on texts and photos printed, application software, print mode, and
type of paper used.
When the machine is turned on and while printing, each ink may be used for protecting the print head and maintaining print
quality.

2. LIST OF ERROR DISPLAY / INDICATION
1-5
Errors and warnings are displayed by the following ways:
1) Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution are displayed on the LCD in text.
2) Warnings during printing from a computer are displayed on the printer driver Status Monitor.
3) Error codes are printed in the "operator call/service call error record" area in EEPROM information print.
Buttons valid when an operator call error occurs:
1) ON/OFF button: To turn the machine off and on again.
2) OK button: To clear and recover from an error. In some operator call errors, the error will automatically be cleared when the
cause of the error is eliminated, and pressing the OK button may not be necessary.
3) Stop/Reset button: To cancel the job at error occurrence, and to clear the error.

2-7. Fax Communication Troubleshooting
(1) Identification of a trouble
A fax machine transmits image data to a receiver through a telephone line. A trouble in any of the transmitter, receiver, and
telephone line can prevent the machine from transmitting image data properly.
1-16
For the best solution to your fax trouble, follow the flowchart below to determine whether it is a communication trouble or not.
(2) Handling of a communication trouble
Follow the procedure below to handle communication troubles.
1) Investigate the condition in which the trouble occurred.
a. User operation at trouble occurrence
- Number of sheets of the document
- Transmission mode
- Timing when the error occurred (e.g. before or after transmission)
- Other settings (e. g. such as automatic dialing)
b. Sample print of a faulty fax reception
c. Message on the LCD at trouble occurrence
d. Activity report at trouble occurrence
e. User name, telephone number, fax number, and model name
f. The other party's user name, telephone number, fax number, model name, and service engineer name
g. Frequency and error type of the trouble
h. The other party's fax condition
- Number of sheets transmitted
1-17
- Communication mode (automatic or manual)
- Whether an error occurred or not
- Reception condition, etc.
Memo: The number of sheets / times of communication and error code can be confirmed in EEPROM information print.
2) Conduct the communication test, by following the flowchart below.
- Perform the operations using the actual line several times each, and record the phenomenon.
- If a communication trouble occurs between a Canon machine and a non-Canon machine, follow the flowchart for the
communication test with a non-Canon machine.
3) Handle the problem based on the investigation and test results.
Memo: If a trouble occurs in communication with a non-Canon machine, and if a Canon machine operates properly without
any problems, it is recommended to let the user understand that the non-Canon machine needs to be examined
accordingly. Since the cause of the trouble may exists in communication ability of the machine, contact a relevant
service contact point of a non-Canon machine. In such a case, the information obtained in step 1) will be a help for
quick solution to the problem.
<Communication test between Canon machines>
Conduct the 3-point communication shown in the diagram.
Test flowchart of communication test between Canon machines:
<Communication test with a non-Canon machine>
Ask a non-Canon machine user to request servicing, and conduct the 4-point communication test shown below.

Notes on replacement
- Before removal of the logic
board ass'y, remove the power
cord, and allow for approx. 1
minute (for discharge of
capacitor's accumulated
charges), to prevent damages
to the logic board ass'y.
- Before replacement, check the
waste ink amount (by service
test print or EEPROM
information print).
[See 3-4. Verification Items,
(1) Service test print, or (2)
EEPROM information print,
for details.]
- The red screws securing the
paper feed motor are allowed
to be loosened. (DO NOT
loosen any other red screws.)

Adjustment / settingsOperation check
After replacement:
1. Initialize the EEPROM.
2. Set the destination in the
EEPROM.
3. Reset the waste ink counter.
4. Correct the CD / DVD and
automatic print head
alignment sensors.
5. Check the ink system
function.
6. Perform the print head
alignment in the user mode.
After replacement:
1. Reset the waste ink counter.
