Canon MG5350 printer wired USB to Dell Inspiron N5110 laptop:
The test printout of lattice and colour strips is perfect but prints recently from the computer have random blank strips across in b&w and colour prints. I've cleaned and deep cleaned, washed through the head, put in new ink pots, checked the USB cable, swapped the USB cable, tried every print mode and still can't cure the problem.
The printer has had a busy 4 years so is something likely to be life-expired?
Any ideas please?
