Cleaning the Timing Strip on Your Canon Printer
The timing strip is a clear, plastic strip approximately ¼” in height positioned horizontally across the
center of the unit, just in front of the carriage drive belt. The timing strip contains many thin black
vertical lines that help determine the carriage position during operation.
During certain uncommon tasks such as the removal of a paper jam, it is possible to inadvertently touch
a lubricated area on the printer’s chassis causing a small amount of grease to be deposited onto the
timing strip.
Grease on the timing strip may result in poor print quality including; mis-aligned or distorted characters,
vertical lines or, in some cases, an inoperable error condition or knocking / grinding noise.
In most cases, it is easy to remove the grease from the timing strip using common household items. If
you wish, you may follow the steps below to remove the grease from the timing strip.
Items needed:
•
Clean, unused cotton swab
•
Small amount of Isopropyl Alcohol or window cleaner
•
Flashlight or other light source
Note: The illustrations will display a PIXMA MX700; however, the parts and cleaning procedure will be
the same for your model.
1)
Power on the printer and open the main access cover (scanning unit cover).
The Print Head Holder (carriage) will move to ink changing (center) position.
