Hi Gemini02,
about our problem and your questions, here below our reply:
What are the toner levels? ALL LEVELS ARE HIGH, WE TRIED TO CHANGE TONERS, WITHOUT SOLVE PROBLEM
Are you using Genuine HP Toners? WE ALWAYS USED ORIGINAL HP TONERS
Is this happening when printing in black or color? IT HAPPENS AS PRINTING IN BLACK AS IN COLOR
Please help me, if it is possible.
