About Canon iPF710 Service Manual
The following rules apply throughout this Canon iPF710 Service Manual:
- Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation. In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal. The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.
- In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'. In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Canon iPF710 Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins. All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine."

Canon iPF710 Printhead
The printhead that mounts on the carriage is an integrated six-color disposable printhead. It has 5,120 nozzles for MBK and 2,560 nozzles for each additional color arranged in a zigzag pattern. If print quality remains unimproved even after a specified cleaning operation, replace the printhead. Replacement about one year after the date of initial unpacking is also recommended.
Canon iPF710 Ink Tank
Ink tanks are disposable.
An ink tank should be replaced when an ink tank replacement prompt message appears or when six months expire after the date of initial unpacking, whichever occurs earlier.
To install ink tanks, open the right cover of the printer. Ink tanks are furnished with a notch for preventing incorrect installation, which will allow the tanks to be installed at the position marked in the right color and nowhere else.
Ink tanks are available in the four dye ink colors of black, cyan, magenta and yellow and the pigment ink color of mat black.
