Canon i860, i865 Service Manual
1. NEW TECHNOLOGIES
(1) Direct digital camera printing
Printing can be performed directly from a digital camera. In addition to Bubble Jet Direct, the Camera
Direct Printing standard, PictBridge, is supported.
The print head alignment, which could not be performed during Camera Direct Printing with conventional
printer models, can now be performed with the i860 / i865. (By pressing the Resume/Cancel button, and
releasing it when the LED blinks 4 times in green, the automatic print head alignment is performed.)

(2) Dye-based black ink adopted
In addition to the pigment-based black ink, dye-based black ink is adopted, enabling printing using black
ink on specialty paper. (In plain paper printing, pigment-based black is used.)
ink on specialty paper. (In plain paper printing, pigment-based black is used.)
(3) Media sense
An optical reflective type media sensor is equipped in the sheet feeder unit, and it can classify
Canon-recommended paper set in the sheet feeder into 4 groups (transparency, glossy photo paper, plain
paper, and coated paper).
The media sensor function is disabled in the following conditions:
<Conditions in which the media sensor does not operate>

<Anticipated troubles and their solutions>
If media sensor detection is incorrect, the following troubles are likely to occur:
i.
In printing on specialty paper, streaks or lines appear, or color hue is improper. (The print quality is
not good.)

Solution: Match the Media Type setting in the printer driver with the paper type actually set.
ii.
In printing on plain paper, printing is smeared, color hue is improper, or black is faint. (The print
quality is not good.)

Solution: In Custom Settings of the Maintenance tab, disable Identify paper type.
(4) Automatic print head alignment
The automatic print head alignment is available via the Resume/Cancel button operation, or via the printer
driver utility.
Through scanning the print pattern as shown below and detecting its reflection density with the automatic
print head alignment sensor (same as the CD-R sensor), the print head is automatically aligned properly.
In the automatic print head alignment, the following items are checked, and, if an error is detected, the
automatic print head alignment failure error is indicated by the LED blinking in orange 11 times:

- Paper width: An error is detected when the paper width is smaller than the specified value.
- Paper length: An error is detected when the paper length is shorter than that of A4 / LTR.
ii.
Faulty printing due to non-ejection of ink
- Ink ejection conditions: An error is detected when non-ejection of ink occurs.
