I am using a Color LaserJet Pro MFP M277dw.  I have multicolored horizontal lines across printed pages.  I have run the cleaning page several times.  I have inspected the cartridges and shook them.  I will get a test page that looks ok, but the next test page will have the lines again.  I replaced the cyan cartridge last month, had no issues,  but now the magenta is very low.  After seeing the lines, I replaced the magenta, but still am having issues.  The colors print fine on the document, but there are additional horizontal colored lines across the page that seem to be the same distance from each other.  I don't know where else I could look to clean any residue.  The lines are straight, so it doesn't appear to be stuck toner transferring onto the page.
