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.)
