Question about Canon PIXMA MP780 All-In-One InkJet Printer

Some colours not printing

Hi there, My printer is not printing all colours. I've done numerous nozzle checks with the result that all colours print apart from yellow and the top black cartridge. I've done the clean, and deep clean process as recommended in the user manual many times but it hasn't cleared. The cartridges are full and my last successful full colour print was just last week. Any ideas gratefully received. Many thanks Judy

I bet you are using non genuine ink, the MP780 will not put up with that ink, you will need a new printhead and maybe a purge unit. Take the machine to your ink supplier and get him to fix it as he supplied the ink

Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

Hi,


The nozzle may be blocked. So take out the colour cartridge and place its nozzle in a bit of water for about 10 mins. Bring it out and dab the nozzle with folded paper. If the tissue is blotted with the three colour it means you have unblocked the nozzle. Try now to print after returning the colour cartridge. You may need to repeat to get good results.

Thank you!!

All colours and black print faded. Black is a

ANSER #1

Assuming that you are using original Canon cartridges or a brand of Compatibles that you have used before.

If print results are blurred, colors are faded or not printed correctly, the pint head nozzles are probably clogged.

Follow the procedure below to print the nozzle check pattern, check the print head nozzle condition, then clean the Print Head. You may have to do this 2 or 3 times.

If printed ruled lines are misaligned or print results are otherwise unsatisfactory, aligning the Print Head may improve print quality.

Caution Do not rinse or wipe the Print Head and ink tanks. This can cause trouble with the Print Head and ink
tanks.

Note Before performing maintenance
Open the Top Cover and make sure that all lamps on the ink tanks are lit red.
If not, see Checking the Ink Status and take an appropriate action.
Increasing the print quality in the printer driver settings may improve the print result.
