MG7760 PGBK head alignment

[Wright4321]

I've done several head alignment chacks/adjustments on my printer – both auto and "manual".

The colour heads (including the "GY' and "BK" heads for colour printing) align perfectly, but the large-capacity "PGBK" head used for text still prints wavy vertical lines and produces blurred or doubled images for about 3 out of every 4 lines of text.

Can anyone suggest a solution?

Hi Wright4321,

Based on your description of the issue, it would appear as though the encoder/timing strip in your printer is dirty or smudged and would need to be cleaned.  To clean the encoder/timing strip, please follow the steps outlined in the following Knowledgebase Article available from Canon's web site:
