Canon MG6620
When printing text some lines are darker than other lines, almost looks bold. Usualy every 3rd or sometimes 4th line is darker.
I cleaned, deep cleaned, aligned heads, cleaned nozzles, replaced ink cartridges etc. Up until today no other problems or jams with printer. Other than replacing ink cartridges, Inside of printer has never been touched.
Same text printed on another printer no problems.
Any suggestions? Thanks.
