iP4300 no longer printing properly

[neene]

I am running iOS 10.11.3 El Capitan, my printer was working fine when all of a sudden it started skipping lines when printing text, images seem to print in full but are missing blacks.  I have done a cleaning (not a deep cleaning) which did not effect the test page print out. Please advise, thank you

Hi neene,

In addition to the cleaning, we recommend performing at least two deep cleanings on the printer to try and resolve the issue. We also recommend performing a print head alignment by following the steps located here.

Should you still experience difficulty, the printer may require servicing.  We ask that you please call 1-866-261-9362, Monday - Friday 10:00 a.m. - 10:00 p.m. ET (excluding holidays) to obtain your servicing options.  There is no charge for this call.
