Keeping Print Quality High - Canon Pixma TR7800 Series Online Manual

Keeping Print Quality High

The key to printing with the optimal printing quality is to prevent the print head from drying or clogging.
Always observe the following rules for optimal printing quality.
Note
• • Depending on the type of paper, ink may blur if you trace the printed area with a highlight pen or
paint-stick, or bleed if water or sweat comes in contact with the printed area.
Never unplug the power cord until the power is turned off!
If you press the ON button to turn off the power, the printer caps the print head (nozzles) automatically
to prevent from drying. If you unplug the power cord from the outlet before the status light is off and the
touch screen is off, the print head will not be capped properly, which will cause drying or clogging.
When unplugging the power cord, check that the status light is off and the touch screen is off.
Print periodically!
Just as the tip of a felt pen becomes dry and unusable if it has not been used for a long time, even if it is
capped, the print head too, may become dried or clogged if the printer has not been used for a long time.
We recommend you to use the printer at least once a month.
