Part of page prints very faint

[cal68]

Printer is printing part of the message very faint. The first two or three lines at the top are dark black and the remainder of the message is so faint it can not be read. The last few lines are normal also. It seems this started after installing latest Windows update. Anyone else having this problem? Anyone have an idea how to fix? Canon MG3620. Full of ink and has been working fine till now.

Hi cal68,

Based on your description of the issue, it woulda appear that the encoder/timing strip inside your PIXMA MG3620 is smudged.  Cleaning this will resolve the issue.

To clean the encoder/timing strip, please follow the steps in this Knowledgebase Article:
