Recently it has been spraying dots on any and all media. I am thinking it is time for a wiper replace, but correct me I am wrong, and also if anyone could please direct me on how to do a wiper replace.
Check your heads with a flashlight, look for hairs, dried ink, or banner strings hanging from the heads. Do a very good head cleaning using the swabs, change the wipers, clean wiper scraper, and do a close look at the caps for hairs, etc... Or, you may have had a bad head crash and scratched your head(s).
Oops! Wiper replacement: turn front power off...then hold the Cleaning button + Power - scroll down to wiper replace - the wipers will come out for easy replacement - simply use tweezers to remove the old wipers and exchange with new.
