Printer issue: the output is streaked.

Hello ;

That's what I was going to suggest > Insist, but if that's already done ??
Have you tried removing all the cartridges and print head (without touching the electronic circuits) and cleaning the inside of the printer with a soft cloth, particularly in the area where the print head carriage is > > 1 blow with a hairdryer (for blowing etc.. and a vacuum cleaner to remove all the "waste")
If it still doesn't work after all that > > Solution ??
Best regards

It works !!!!!!!!!!!!!!!!! Yay !
After 15 attempts of all kinds and just as many printing trials, I did as you said. Except I cleaned, blew, and vacuumed in the wrong place, where the cartridges were (after removing them). Then, no better.
After that, I reread what you wrote. Not knowing where the carriage path was, I cleaned, blew, and vacuumed everywhere. The next attempt scared me, the paper got stuck (which had never happened to me before) and the printer started making terrible noises. I removed the paper and saw where the carriage passes. It was full of ink. For those who don’t know, it’s the metal bar at the bottom, above the rollers that move the paper forward.
Finally, I restarted a cleaning through the printer. And for the next attempt, Bingo!

Thank you very much, jmarion3 for your help.

Have a good day.

How can I indicate that the issue is resolved?
