Question about HP DeskJet 640c InkJet Printer
After printing one project, the printer starts flashing between the green and orange lights . It won't print again until I turn it off and then on again.,
Regards Marea Keppie
Open t cover, behind t catrage u will find a steel rod. Clean t rod with cotton but make sure t cotton or any thing dosn't touch plastic strip which is behind that rod. After cleaning t rod take a cotton bud dipped in machine oil and grease t rod. then close t cover and let t catrage move.
If u have given print command cancle it and restart ur pc. Your printer will work properly. This problem will come again so make sure u keep t rod clean ( clean it once a week or accordind to ur use).
It occurs due to t carbon.
