New Technologies - Canon PIXUS 50i Service Manual

1. NEW TECHNOLOGIES

(1) Direct digital camera printing
Printing can be performed directly from a digital camera. During the direct digital camera printing, the
following functions are not available:
- Print head alignment
- Remaining ink amount detection
*1: If the print head alignment has not been performed via the computer connected to the printer,
uni-directional printing is performed, and the print speed is lower than that of bidirectional printing.
To enable bidirectional printing, connect the printer to the computer, and perform the print head
alignment.
(2) Reduction of waste ink amount
The following technologies prevent unnecessary cleaning of the print head, and reduce the number of times
the print head cleaning is performed and the ink amount purged during the cleaning. As a result, the waste
ink amount is reduced.
- Ink sensor installed:
By the ink sensor, the exact timing to perform the cleaning at ink tank replacement is detected.
(Previous printers determined the cleaning timing by a period of time the print head cover is open.)
- Separate cleaning of black or color:
In addition to the conventional cleaning of both black and color, separate cleaning of black or color is
now available in any of the following conditions:
- Manual cleaning (only via the printer driver utility)
- Deep cleaning
- At ink tank replacement
- Timer cleaning
- If the print head has not been capped for 1 hour or longer until power-on
- Internal structure of the print head and cap:
The structure of the ink flow path inside the print head and the cap has been changed from that of the
previous print heads, to lessen the amount of ink evaporated. As a result, the timer cleaning interval
has been increased.
(3) Plug & Play infrared (IrDA) communication (at default settings)
Plug & Play infrared communication has been supported.
For troubleshooting of infrared communication problem(s) with a computer which does not support Plug &
Play, the Plug & Play infrared communication can be switched between on (enabled) and off (disabled) in
the following procedure:
<How to disable/enable Plug & Play infrared communication>
With the printer power turned on, press and hold the Resume/Cancel button until the LED blinks 8 times,
and release it.
