Question about HP Officejet Pro L7780 All-In-One InkJet Printer
Clogged Inkjets? Could they be white Lines in your prints?
Assuming your inkjet printer worked OK before a period of non use? And you do not have any strange flashing lights, or an obvious electrical fault or malfunction?
Then most about 98% are more likely to be an ink clog which just needs to be unclogged using something like WARMED Magic Inkjet Flush
Basically, if a print head has been left unused for some time... moisture inside the ink begins to evaporate and instead of liquid ink, a thick inky jelly begins to form inside the print head.
When this occurs white lines appear in prints and most people not realising the problem, will replace their inks... But when that does not work. Some assume they have an electrical fault, and replace their print head, others will replace their printer !
But provided there is no obvious print head damage? In 98% of cases it simply needs a little patience and WARMED Magic Inkjet Flush injecting directly into the print head to dissolve the dried ink trapped inside. This will dissolve the clog and allow your expensive ink to flow once again. Most will then print as new.
Hope this helps to explain.
